Samsung s8 description. Samsung Galaxy S8 and S8 Plus Specifications "from A to Z. Comparison with Competitors
Long, frameless, with great camera and the highest performance
Recently samsung officially presented in Russia its long-awaited flagship smartphones Galaxy S8 and Galaxy S8 +. Despite major setbacks in the recent past, Samsung's flagship devices not only continue to be the main competitor apple iPhonesbut they are also among the most technically advanced Android smartphones. Compared to the previous (seventh) generation, a lot has changed here, from the overall design to the location individual elements in particular, not to mention the improved hardware and updated software stuffing. Not all changes are for the better, but there are so many of them that we can say that Samsung has decided to start from scratch. It should be noted that, to the delight of many, the difference between the Galaxy S8 and Galaxy S8 + models is only in the dimensions, almost everything else is the same. There are no various modifications with a variable amount of built-in memory or RAM, different performance, the presence or absence of certain elements. The user does not need to bother with the choice, it is enough just to decide on the preferred device dimensions. The technical characteristics of both models are almost identical, and we will begin with listing them. this reviewusing the Galaxy S8 + as a reference.

Contents of delivery
Samsung Galaxy The S8 + received a stylishly designed matte black cardboard box with a laconic design. The lid cannot be removed completely, it folds back like a casket. Contents are neatly packaged in separate cells.
The set, in the best traditions of Samsung, turned out to be extensive. The smartphone comes with a USB Type-C connection cable, network adapter with a variable output current and voltage of 5/9 V 1.67 / 2 A, a key of an unusual shape for removing cards, a Micro-USB - USB Type-C adapter, a second USB - USB Type-C adapter.
The company also included high-quality wired double-driver AKG stereo headphones with a set of interchangeable in-ear pads.
Appearance and usability
The design of the Samsung Galaxy S8 / S8 + turned out to be unusual and attractive. The streamlined body is completely made of metal and glass, there is no plastic here. A metal frame rounded on all sides, symmetrically tapering at the sides and expanding at the top and bottom ends, connects two glass panels - the front and rear. The cover is Gorilla Glass 5, the glasses have noticeable curvatures on the sides. The frame in the front plane of the screen is completely hidden behind the bend of the glass, so here we can talk about a truly frameless version.
The case of the Samsung Galaxy S8 + is absolutely symmetrical, the back side is also completely covered with Gorilla Glass 5 with curved edges. The edges of the glasses are rounded so strongly that they almost seamlessly (not counting the frames) merge into one another, creating a finished shape without a single sharp corner and straight edge. For this form, Samsung marketers have dubbed their new brainchild “smartphone without borders”.
Samsung Galaxy S8 + looks very attractive. And although this design may seem too "licked" and "pampered", but such are the modern realities, the absolute majority of users liked it.
Due to the unusual aspect ratio of the display (not 16: 9, but 18.5: 9) the case turned out to be very elongated in height. At the same time, the absence of a frame on the sides of the screen in the front plane made it possible to make the body so narrow that it is quite comfortable to hold it in the hand even with a screen diagonal of 6.2 inches. True, the device is quite slippery due to its glass panels, smooth frame and streamlined shape.

The curved edges of the front glass work in conjunction with the corresponding software in the same way as in previous models series Galaxy Edge... A complete set of elements can be found above the screen, including an LED event indicator and even an iris scanner.
The scanner works tolerably, but the very process of setting the blocking and constant recognition is quite tedious, because this system works only under certain light conditions and at a certain distance from the eyes. It is much easier and faster to use the fingerprint scanner, although its location here causes some bewilderment.
There are no more control buttons under the screen, only on the screen itself. This is not typical for Samsung, its galaxy smartphones there was always a hardware key on the front (in the latest models - with an inscribed fingerprint sensor). Now its place is taken by a virtual button on the screen, but it is also not quite ordinary. In order for the static button, which is constantly illuminated in the Always On Display mode, not to cause pixel burnout, it was made movable. Thus, at first glance, the central button on the screen, which is static at first glance, is in fact constantly shifting imperceptibly in different directions.
The fingerprint scanner has been moved to the back. At the same time, it is strongly shifted from the center to the right, so that it is inconvenient for a left-hander to reach with his finger. In addition, the tactile platform of the fingerprint sensor does not differ from the neighboring elements, it is difficult to feel it blindly, you need to get used to it. In general, this is, perhaps, the most unusual and inconvenient variant of the location of this element from all of us previously encountered, Samsung has again been overly clever with a fingerprint sensor.
Next to the scanner, you can find a camera module with a flash, as well as a heart rate sensor familiar to Samsung smartphones. None of the elements protrude beyond the surface, so the smartphone is stable on the table, does not sway when you touch the screen. The flash is as bright as possible.
There are no complaints about the operation of the fingerprint scanner itself, it works quickly, clearly and accurately. But, as already mentioned, reaching for him, holding the smartphone in his left hand, is very uncomfortable.
The slot for installing cards is located on the upper end. The cover of the removable slide, on which the cards are stacked, has a rubberized gasket, since the Samsung Galaxy S8 +, like the LG G6, meets the IP68 protection category, that is, the case is completely protected from dust and can be immersed in water to a depth of 1.5 m for 30 minutes. However, the developers did not go further: the design here is not designed for harsh operating conditions, like the LG G6, so the hero of the review does not have a certification of the military standard.
It uses a standard hybrid slot that accepts either two Nano-SIM cards or one SIM and one microSD card. The slide is made of flexible plastic, the device itself reports on the need to tightly close the connector cover to protect it from water.
The volume control button has been moved to the left side edge, here it is adjacent to a separate key for calling the Bixby smart assistant, with which you can work with available services and applications through touch screen, voice or text commands. The power key remained on the right side edge. The buttons are not very large, but the handling is quite comfortable, the keys are easily groped blindly.
All other interface elements are located at the bottom end. A USB Type-C connector is installed here, supporting connection external devices in USB OTG mode, the main speaker is brought here, as well as a 3.5 mm headphone jack and a spoken microphone hole. Surprisingly, the developers were unable to install any of the elements exactly, each of them turned out to be offset relative to the longitudinal axis of the end, which spoils the impression a little.
Having studied the structure of the Galaxy S8 + case, let's compare it with the previous one galaxy model S7 Edge. With the naked eye, you can see that the width of these smartphones is almost identical.
However, the Galaxy S8 + is equipped with a more elongated display with a custom aspect ratio, which allowed for more surface area under the screen. As a result, the 6.2-inch Galaxy S8 + sits in the palm of your hand just as comfortably as the 5.5-inch Galaxy S7 Edge.
In addition, the sides of the body of the review hero have become less slippery due to the increased width of the metal frame: the curved edges of the screen on the Galaxy S8 + have been reduced, the frame is now exactly in the middle between the front and rear panels. So, in general, the changes were only beneficial to the new product.
Samsung Galaxy S8 + presented at russian market in three colors: black ("Black Diamond"), gray ("Mystical Amethyst") and gold ("Yellow Topaz").
Screen
Samsung Galaxy S8 + features a Super AMOLED display with protective glass Corning Gorilla Glass 5 with highly rounded edges. The physical dimensions of the screen are approximately 70 × 142 mm with a diagonal of 6.2 inches, that is, the aspect ratio is 18.5: 9. The screen resolution is 2960 × 1440, the dot density is about 529 ppi. The corners of the screen, like the LG G6, are rounded, there are no side frames in the front plane of the screen, the upper and lower segments surrounding the screen are only about 8.5 mm high.

The brightness of the display can be adjusted manually or set automatic settingsbased on the operation of the ambient light sensor. HDR10 mode supported. The AnTuTu test diagnoses support for 10 simultaneous multitouch touches. There is a vision protection mode (preventing eye fatigue). In the Always-on mode, the off screen displays information about the current time and date, as well as about missed events.
In the screen settings section, you can choose the resolution and applications that should be used in full screen proportions. It seems that the developers first made a screen with an unusual aspect ratio, just so that it was “not like everyone else's”, and then they added various “crutches” to the software so that the programs would work normally with such a screen.

Detailed expertise using measuring instruments conducted by the editor of the sections "Monitors" and "Projectors and TV" Alexey Kudryavtsev... Here is his expert opinion on the screen of the test sample.
The front surface of the screen is made in the form of a glass plate with a mirror-smooth surface, resistant to scratches. Judging by the reflection of objects, the anti-glare properties of the screen are better than that of the Google Nexus 7 (2013) (hereinafter simply Nexus 7). For clarity, here is a photo in which a white surface is reflected in the turned off screens (on the left - Nexus 7, on the right - Samsung Galaxy S8 +, then they can be distinguished by their size):
The screen of the Samsung Galaxy S8 + is slightly darker (brightness in the photos is 107 versus 115 for the Nexus 7) and does not have a pronounced shade. The doubling of reflected objects on the Samsung Galaxy S8 + screen is very weak, which indicates that there is no air gap between the layers of the screen. Due to the smaller number of boundaries (such as glass / air) with very different refractive indices, screens without an air gap look better in conditions of intense ambient light, but their repair in case of cracked outer glass is much more expensive, since the entire screen has to be changed. The outer surface of the Samsung Galaxy S8 + screen has a special oleophobic (grease-repellent) coating (effective, better than the Nexus 7), so fingerprints are much easier to remove and appear at a slower rate than in the case of regular glass.
When displaying the white field in full screen and with manual brightness control, its maximum value was 370 cd / m² under normal conditions and rises to 580 cd / m² in very bright light. You also need to take into account the fact that in this case, the smaller the white area on the screen, the lighter it is, that is, the actual maximum brightness of the white areas will almost always be higher than the specified value. For example, when displaying a white field on half of the screen and black on the other half, for the above conditions, we obtained values \u200b\u200bof 460 cd / m² and 725 cd / m². As a result, readability in the daytime in the sun should be at a good level. Minimum value - 1.6 cd / m². The reduced brightness level allows you to use the device without any problems even in complete darkness. Working automatic adjustment brightness based on the light sensor (located to the left of the front speaker slot). The operation of this function depends on the position of the brightness adjustment slider, with which the user can try to set the desired brightness level in the current conditions. If the brightness slider is set to maximum in an office environment, then in complete darkness the auto-brightness function reduces the brightness to 6.4 cd / m² (a bit dark), in an office lit with artificial light (about 550 lx) sets it to 340 cd / m² (excessively bright) , in a very bright environment (equivalent to a bright day outdoors, but no direct sunlight - 20,000 lux or slightly more) increases to 545 cd / m² (sufficient). If, in complete darkness and in an office environment, set the brightness a little higher and lower, then the screen brightness for the three conditions mentioned above is as follows: 13, 180, 545 cd / m² (ideal combination). It turns out that the automatic brightness control function works adequately and to some extent allows the user to customize his work for individual requirements. At any brightness level, there is significant modulation with a frequency of about 60 or 240 Hz. The figure below shows the dependence of brightness (vertical axis) on time (horizontal axis) for several values \u200b\u200bof brightness adjustment:
It can be seen that at the maximum brightness and close to it, the modulation amplitude is not very large, as a result, there is no visible flicker. However, when the brightness decreases, modulation appears with a large relative amplitude, its presence can already be seen in the test for the presence of a stroboscopic effect or simply with rapid eye movement. Depending on individual sensitivity, such flickering can cause increased fatigue.
This screen uses a Super AMOLED matrix - an active matrix on organic light-emitting diodes. A full color image is created using subpixels of three colors - red (R), green (G) and blue (B), but there are twice as many green subpixels, which can be referred to as RGBG. This is confirmed by a fragment of a micrograph:
For comparison, you can see the gallery of photomicrographs of screens used in mobile technology.
In the fragment above, you can count 4 green subpixels, 2 red (4 halves) and 2 blue (1 whole and 4 quarters), while repeating these fragments, you can lay out the entire screen without gaps and overlaps. For such matrices, Samsung has introduced the name PenTile RGBG. The manufacturer considers the screen resolution for green subpixels, for the other two it will be two times lower. The location and shape of the subpixels in this version is close to the case of the screen of the Samsung Galaxy S4 and some other newer ones. samsung devices (and not only) with AMOLED screens. This PenTile RGBG version is better than the old one with red squares, blue rectangles and green subpixel stripes. Nevertheless, some uneven contrast borders and other artifacts are still present. However, due to the very high resolution they have only minimal effect on image quality.
The screen has excellent viewing angles. True, when deviated even at small angles, the white color alternately acquires a light blue-green and pinkish tint, but the black color remains simply black at any angle. It is so black that the contrast setting is not applicable in this case. For comparison, here are the photos on which the screens of the Samsung Galaxy S8 + (profile Main) and the second comparison participant displayed the same images, while the brightness of the screens was initially set to about 200 cd / m2, and the color balance on the camera was forcibly switched to 6500 K.
White box:
Note the good uniformity of brightness and color tone of the white field (except for a slight darkening and a change in hue towards the curved edges).
And the test picture (profile Main):
The color rendition is good, the colors are moderately saturated, the color balance of the screens is slightly different. Recall that photography can not serve as a reliable source of information about the quality of color and is provided only for a conditional visual illustration. In particular, the pronounced reddish tint of white and gray fields present in the photographs of the Samsung Galaxy S8 + screen is visually absent when viewed from a perpendicular view, which is confirmed by hardware tests using a spectrophotometer. The reason is that the spectral sensitivity of the camera sensor does not exactly match this characteristic of human vision. Note that in this case the picture occupies in height (with this screen orientation) the entire area available for image display and goes over the curved edges of the screen, which leads to darkening and color distortion. Also, in the light, these areas almost always glare, which further interferes when viewing images displayed in full screen. And even the picture of films with an aspect ratio of 16: 9 goes to the folds, which greatly interferes with watching a movie.
The photo above was taken after selecting a profile Main in the screen settings, there are four of them:
Profile Adaptive display differs in some kind of automatic adjustment of color rendition to the type of displayed image and the surrounding conditions:
Saturation and color contrast are greatly increased, looks awful. What happens when you select the two remaining profiles is shown below.
AMOLED movie:
Saturation and color contrast are also increased, but not as much.
AMOLED Photo:
Saturation is slightly lower, but color contrast is slightly higher than in the case AMOLED movie.
Now at an angle of approximately 45 degrees to the plane and to the side of the screen (profile Main).
White box:
The brightness at an angle on both screens has noticeably decreased (to avoid severe darkening, the shutter speed is increased compared to previous photos), but in the case of Samsung, the drop in brightness is much less pronounced. As a result, with formally the same brightness, the Samsung Galaxy S8 + screen visually looks much brighter (compared to LCD screens), since the screen mobile device often you have to look at at least a slight angle.
And the test picture:
It can be seen that the colors have not changed much on both screens and the brightness in samsung smartphone at an angle noticeably higher. The switching of the state of the matrix elements is performed almost instantly, but at the turn-on front there may be a step with a width of about 17 ms (which corresponds to a screen refresh rate of 60 Hz). For example, this is how the dependence of brightness on time looks like when switching from black to white and vice versa:
In some conditions, the presence of such a step can lead to plumes trailing behind moving objects. However, dynamic scenes in films on OLED screens are distinguished by high definition and even some "jerky" movements.
The gamma curve plotted using 32 points with equal intervals in terms of the numerical value of the shade of gray showed that there is no significant blockage either in the highlights or in the shadows. Indicator approximating power function is equal to 2.09, which is slightly less than the standard value of 2.2, while the real gamma curve deviates little from the power dependence:
Recall that in the case of OLED screens, the brightness of image fragments dynamically changes in accordance with the nature of the displayed image - it decreases for generally light images. As a result, the obtained dependence of brightness on the hue (gamma curve), most likely, does not correspond a little to the gamma curve of a static image, since the measurements were carried out with sequential output of shades of gray on almost the entire screen.
Color gamut in case of profile Adaptive display very wide:
In the profile AMOLED movie coverage is slightly narrower:
When choosing a profile AMOLED Photo the coverage is compressed to the boundaries of Adobe RGB:
When choosing a profile Main coverage is compressed to sRGB borders:
Without correction, the spectra of the components are very well separated:
In case of a profile Main with maximum correction, the color components are already noticeably mixed with each other:
Note that normal sRGB-optimized images appear unnaturally saturated on screens with a wide gamut without proper color correction. Hence the recommendation - in most cases, watching movies, photographs and everything natural is better when choosing a profile Main, and only if the photo was taken on the Adobe RGB setting, it makes sense to switch the profile to AMOLED Photo... Profile AMOLED moviedespite the name, the least suitable for watching movies and anything else.
The gray scale balance is good. The color temperature is close to 6500 K, while this parameter does not change very much in a significant part of the gray scale, which improves the visual perception of color balance. The deviation from the blackbody spectrum (ΔE) remains below 10 units for most of the gray scale, which is considered a good indicator for a consumer device:
(In most cases, the darkest areas of the gray scale can be ignored, since the color balance there is not very important, and the error in measuring color characteristics at low brightness is large.)
For some reason, only when choosing a profile Adaptive display it becomes possible to adjust the color balance by three adjustments of the intensity of the primary colors, but due to the too wide color gamut, it is in this profile that it makes no sense to correct the balance.
Let's summarize. The screen has a very high maximum brightness and has excellent anti-glare properties, so the device can be used outdoors without any problems, even on a sunny summer day. In complete darkness, the brightness can be lowered to a comfortable value. It is permissible to use a mode with automatic brightness adjustment, which works adequately. The advantages of the screen include an effective oleophobic coating, as well as a color gamut close to sRGB and a good color balance. At the same time, let's recall the general advantages of OLED screens: true black color (if nothing is reflected in the screen), noticeably less than that of an LCD, the drop in image brightness when viewed from an angle. The disadvantages include modulation of screen brightness. Users who are particularly sensitive to flicker may experience fatigue as a result. However, the overall screen quality is very high. Separately, we note that from the point of view of image quality, curled edges only harm, since this design find introduces very noticeable color tone distortions and reduces brightness at the edges of the picture, and in ambient light conditions leads to inevitable glare at least along one long side of the screen.
Camera
The front 8-megapixel camera does not receive its own flash, but it has a fast f / 1.7 lens and even supports intelligent autofocus with face detection. As a front flash, you can use the "fill" bright illumination of the screen directly at the moment of shooting. Naturally, there is a mode for retouching selfie photos. Takes off front-camera not bad for its level, there are no special complaints about detail and sharpness, but it's hard to say that this camera is in some way better than analogues from Huawei, for example. Not bad, but nothing more.

The main camera uses a 12-megapixel sensor with a pixel size of 1.4 microns, as well as a fast f / 1.7 aperture lens, optical stabilization system and Dual Pixel technology, which is designed to provide fast enough autofocusing to capture even the sharpest movements in low light conditions. There is a very bright LED flash.
Shoots the camera in automatic or manual mode... In mode manual settings you can adjust the shutter speed (from 1/24000 to 10 s), sensitivity (up to ISO 800), white balance and exposure compensation. There is the possibility of retouching images, support for HDR auto and a selective focus mode for changing the depth of field on the finished image. Also, the camera is connected to an intelligent bixby assistant, which must recognize objects of shooting, find places and translate texts from the screen.
Camera2 API can be used to transfer camera control third-party applications... It is also possible to save images in RAW.

The camera can shoot video in 4K resolution (3840 × 2160), but only at 30 fps, and 60 fps is available only in Full HD (1920 × 1080). There is also a shooting mode at an intermediate resolution of 2560 × 1440, also at 30 fps. There is an optical image stabilization feature that really makes handheld shooting extremely smooth. In any of the resolutions, the camera copes very well with video: sharpness, color rendition and detail are normal, there is enough brightness, artifacts and slowdowns are out of the question. There are no complaints about sound recording either: the microphone sensitivity is high, the sound is clear, loud, the noise reduction system adequately copes with the wind noise.

Samsung continues to improve the quality of its cameras. The megapixel race, fortunately, has been forgotten, and now the manufacturer pays more attention to detail. Even in complex scenes, the camera does not forget about small details, so the images look good even in low light. Soapiness is gradually disappearing, which means that the algorithms of the program have improved. The program has practically ceased to "eat" the details, and sharping is almost invisible. Of course, if you look closely, you can find both, but this is nit-picking.
A laboratory test confirms that the camera has not changed much from the previous generation. However, there are differences, they simply lie in the little things that are difficult to reflect on the stand. For those who like to tinker with photo processing, the manufacturer has made a very good RAW, which in some situations really allows you to get a result better than an intra-camera JPEG.
In general, the camera turned out to be quite flagship and will perfectly cope with many different scenes.
Telephone part and communications
The communication capabilities of the Samsung Galaxy S8 + include support for the advanced LTE Cat.16 technology, all three LTE FDD frequency bands of interest to us (Band 3, 7, 20) are supported, and there is also support for four TDD LTE bands (Band 38-41). It supports two Wi-Fi bands (2.4 and 5 GHz), there is Bluetooth 5.0 LE, you can organize a wireless access point via Wi-Fi or Bluetooth channels. The developers claim that thanks to support for Wi-Fi 1204-QAM and LTE Cat.16 standards, the download speed compared to previous flagships Samsung Galaxy S7 / S7 edge is increased by 20% both over Wi-Fi and over the mobile Internet. The device behaves confidently in the city limits of the Moscow region, the quality of signal reception raises no objections, the device demonstrates high speeds in the usual testing places, and quickly restores communication after a break.
There is an NFC module in the device, but it does not support work with electronic travel cards. The USB Type-C connector supports connecting external devices in USB OTG mode, the corresponding adapter is included in the accessory kit. The data transfer rate between a computer and a smartphone via a cable connected in the case of a PC to the USB 3.1 Type-C ports is about 26 MB / s.
The navigation module works with GPS (with A-GPS), with domestic Glonass and with the Chinese Beidou. The first satellites during a cold start are detected within the first seconds, the positioning clarity is maximum. There is a built-in magnetic compass.

The phone application supports Smart Dial, that is, when dialing a phone number, a search is immediately carried out by the first letters in contacts. In the conversational dynamics, the voice of a familiar interlocutor is well recognizable, there is no extraneous noise, the sound is natural, clear, the volume reserve is sufficient. The power of the vibrating alert is much higher than the average level; its intensity can be changed manually.

Software and multimedia
As a software platform, the Samsung Galaxy S8 + uses Android OS version 7.0 Nougat with its own proprietary shell. There is a convenient opportunity to quickly transfer all data from an old smartphone to a new Samsung Galaxy S8 or S8 + using the OTG adapter that is included in the package.
First of all, it should be noted that the enlarged display with a changed aspect ratio and high resolution provides more space for any information, text or graphics, so a lot of attention has been paid to the dual-window mode. Not every application here can be made to work in a small window; for this, each has a corresponding icon displayed in the menu of the last opened programs. That is, you first need to start and minimize the application in order to understand whether it has the ability to work in two-window mode, and then find the second one. Not a very simple and intuitive option, but you can get used to it. In addition, these windows can be resized. There is also the possibility of reducing the entire working area of \u200b\u200bthe screen for ease of control with one hand. We cannot say that this functionality is convenient in practice, since all elements on the screen become too small, especially the buttons of the virtual keyboard, but there is such a possibility.

Due to the non-standard aspect ratio of the screen, the video in the player is displayed with black bars on the sides, but using scaling, the image can be stretched to the very edges of the screen. Some games have reported possible display issues, but overall we haven't encountered any unsolvable issues.
Another feature of the Samsung Galaxy S8 + screen is the ability to use its curved sides, available for interaction with fingers due to the lack of frames. There is nothing new here: as before, an illuminated virtual strip can be displayed on the side of the screen, when pressed, a menu is opened that is responsible for quick contacts and instant access to the most used applications. Also here it becomes possible to select and save any part of the screen with further text recognition.

But of course, the main feature of the software of the new Korean smartphones was the emergence of Samsung's voice assistant - Bixby, which is a direct competitor to both Siri and Google Assistant, which, by the way, remained in place. As planned by the developers, Bixby will be able not only to answer questions by collecting information on the Web, but also to identify a product using a camera and search for it on Amazon, translate texts in real time, and recognize landmarks. But the functions that will allow you to fully control the smartphone through voice commands are not yet available and will appear later.

 |
 |
 |
As already mentioned, the smartphone's camera is paired with the Bixby smart assistant, which is supposed to recognize subjects, find places and translate texts from the screen. True, in practice, for the Russian realities, all this is still difficult for him. Even if the main language of the device is Russian, the program will persistently offer to translate from any other language, but not from Russian. The assistant also does not know everything yet. At the same time, there were no problems with the translation from English into Russian.

There are very few additional programs, and those that exist are represented mainly by a set of Microsoft applications. Of particular note is Game Launcher, a handy game aggregator that automatically collects all installed game applications in one place, and also provides additional functions related to this. For example, it is possible to start recording the gameplay from the screen right during the game, with its further broadcast on the network. You can also use Game Launcher to improve system performance when launching selected games to enhance your gaming experience.

For listening to music, only a regular Google Play Music player is provided, supplemented by a powerful set of manual settings and equalizer presets, as well as Adapt sound technology for headphones. The smartphone comes with AKG dual-driver headphones with a very good sound quality for their level. But if everything is fine with the sound in the headphones, then the main speaker of the smartphone is not so impressive. It produces a rather monotonous and flat sound, without noticeable depth and saturation, although there are no complaints about purity and volume reserve.

Performance
The hardware platform of the Samsung Galaxy S8 + is built on the Samsung Exynos 8895 Octa SoC with 8 cores in two clusters: 4 Exynos M1 cores up to 2.3 GHz and 4 ARM Cortex-A53 cores up to 1.7 GHz. This SoC is made using the latest 10nm process technology. Responsible for graphics processing is the Mali-G71 video accelerator with support for the Vulkan graphics API. The amount of RAM is 4 GB, and the internal memory is 64 GB, of which about 1.6 GB of RAM and 52.5 GB of ROM are initially free.
It is worth noting that traditionally for Samsung Galaxy devices can be based on different SoCs: in this case it is Qualcomm Snapdragon 835 or Exynos 8895. As always, the question of supply of this or that modification will depend on the region. The smartphone we received for tests ran on the Samsung Exynos 8895 platform.

According to the results of all SoC tests, without exception, Samsung Exynos 8895 showed the maximum results, this is the most powerful mobile platform at the moment of all we tested. Accordingly, the Samsung Galaxy S8 + is one of the most powerful smartphones available today, with a significant headroom for future updates. The smartphone can confidently cope with any tasks in real scenarios, and thanks to the powerful video accelerator, it behaves perfectly in the most demanding games. These videos of the gameplay in Modern Combat 5 and in Mortal Kombat X were recorded by the built-in means of the smartphone itself using the Game Launcher application.
Benchmarking AnTuTu and GeekBench:
All the results obtained by us when testing the smartphone in the latest versions of popular benchmarks, we have summarized for convenience in tables. Several other devices from various segments are usually added to the table, also tested on similar latest versions of benchmarks (this is done only for a visual assessment of the obtained dry numbers). Unfortunately, within the framework of one comparison, it is impossible to present the results from different versions of benchmarks, therefore, many worthy and relevant models remain "behind the scenes" - due to the fact that they once passed the "obstacle course" on previous versions of test programs.

Testing the graphics subsystem in gaming tests 3DMark, GFXBenchmark and Bonsai Benchmark:
When testing in 3DMark for the highest performing smartphones, it is now possible to run the application in Unlimited mode, where the rendering resolution is fixed at 720p and VSync is disabled (which can cause the speed to rise above 60 fps).

Browser cross-platform tests:
As for benchmarks for evaluating the speed of the javascript engine, you should always make allowances for the fact that the results in them significantly depend on the browser in which they are launched, so that the comparison can be truly correct only on the same OS and browsers, and this possibility is available when testing not always. In the case of Android OS, we always try to use Google Chrome.

Testing has traditionally been conducted at typical power consumption levels without using power saving features. In the settings of the Samsung Galaxy S8 +, you can find operating modes from high-performance to economy, the choice of which will affect a lot, right down to the brightness and even the screen resolution.
Continuous reading in the Moon + Reader program (with a standard, light theme) at the minimum comfortable brightness level (the brightness was set to 100 cd / m2) with auto scrolling lasted 21.5 hours until the battery was fully discharged, and with continuous high quality video viewing (720p ) with the same brightness level via a home Wi-Fi network, the device operates up to 14.5 hours. In 3D games mode, the smartphone can work for more than 5 hours.
The smartphone should support fast charging, but we were not able to test this, since at the time of writing this review, the test device did not come with an AC adapter. However, from a conventional charger (5 V 2 A), the device charges quite quickly, for about an hour and a half with a current of 1.75 A at a voltage of 5 V. Wireless charging is also supported (WPC and PMA).
Outcome
The prices for the Russian market are as follows: On April 28, the Galaxy S8 and S8 + smartphones went on sale in Russia at a suggested retail price of 54,990 and 59,990, respectively. It is not entirely clear why the difference in the cost of devices of the same functionality with a slight difference only in the size of the display and the battery is as much as 5 thousand. Be that as it may, in the case of the Samsung Galaxy S8 + for 60 thousand, the manufacturer offers one of the best smartphones in many respects, including camera quality, hardware platform performance and very advanced communication capabilities, in an attractive and very unusual body, as well as with a lot of additional functions, many of which, however, were available in the previous models of the series.
At the same time, it cannot be said that the smartphone has become some kind of breakthrough, a new word in the creation of mobile devices and is completely devoid of disadvantages. A single main camera, although it is one of the best on the market, still looks rather strange against the background of the general movement towards increasing the number of modules. Also, we cannot praise the sound of the main speaker: in terms of sound, the device is clearly inferior to the flagship smartphones Apple and Huawei. The decision to move the fingerprint scanner to the back, and even to such an unfortunate location, was also highly questionable. Well, one cannot but recall the recent problems with the ignition of the batteries of Samsung mobile devices, against the background of which users may now be wary of paying a very high price, which the manufacturer asked for its mobile novelties, right away. And nevertheless, interest in the flagship devices of the Korean company has not weakened, it can be seen. Even those who were not going to shell out 60 thousand rubles for a smartphone are now eagerly discussing its capabilities on the Internet. However, something in the testing process remained undisclosed for us as well, since we did not have the final commercial sample in our hands. Most likely, we are still waiting for, at least, a meeting with the brought to mind Bixby assistant, as well as with camera firmware updates, which may well expand its already remarkable capabilities.

Samsung is one of the leading manufacturers of mobile phones and tablets today. The lineup of Samsung phones contains devices of various classes - from budget devices with a minimum of functions to top-end expensive models incorporating the latest achievements in engineering. In this article, you will learn all about these phones.
Flagship
For many years, the flagship of this company has been the Galaxy S series, which is currently being produced in the seventh generation. It is also possible to purchase the previous Galaxy models in the mobile shops, but they are no longer produced.
To date, the lineup of Samsung phones is headed by Galaxy S7. In the device, the company used all the developments and added support for all the functions that are at their disposal. The device is still controlled by Android. The heart of the smartphone is an 8-core processor, a 4GB RAM module and a 32GB or 64GB hard drive, depending on the version. If this is not enough, you can always install a memory card with a capacity of up to 200 GB.
The smartphone display is worthy of special praise. The large 5.1-inch screen with 2K resolution will surprise even the most sophisticated user. The display has the best viewing angles and color reproduction of any competitor. The only worthy rival today is the Apple iPhone 6 and all its modifications.
The Galaxy S7 has a Note version. The gadget has an enlarged screen - 5.7 inches. The rest of the characteristics remained the same. The device was created for those who found the display of the main model small.
Middle price segment
Next, the lineup of Samsung phones is continued by the Galaxy J line. In terms of technical equipment, this series is slightly weaker than the flagship, but at a cost much more profitable. The J7 is equipped with a 5.5-inch Full-HD display. Here is the same processor with 8 cores, but it has cut frequencies. The device is controlled by the operating system "Android" version 5.1. The amount of RAM is 3GB. For storage, there is a 16 GB hard drive and an additional slot for memory cards up to 128 GB.
Budget smartphones
The lineup of Samsung phones continues with a more budget device - Galaxy J1. For a modest price, you get a pretty productive device. It has a processor with 4 cores, 1 GB of RAM and 8 GB of storage with support for memory cards up to 128 GB. The screen resolution is a bit upsetting - only 800 by 480 pixels. However, with a small diagonal of 4 inches, the image looks good. The picture is distorted only at strong inclinations, practically does not fade in the sun.
Samsung phone (metal case): lineup
The company presented a separate line of devices in a completely metal case. The smartphone has become a pioneer in this area. The creators emphasize that the main thing in it is the appearance and stylish design, and not technical equipment. Therefore, it is worth purchasing A7 only for the metal case. If you are looking for performance, then the S range is the best choice.
This is the model range of Samsung mobile phones for 2016. In addition, you can purchase all previous models if you find them in online stores or telecom stores. This article describes only the actual devices that the company produces at the moment.
The Samsung Galaxy S8 phone was released relatively long ago by industry standards - March 29, 2017. But thanks to the power reserve laid down by the manufacturer, it remains a relevant smartphone to this day. The model differs from its predecessors by the enlarged screen, as well as the absence of the "home" button. It was replaced by a tactile element - it is located under the glass. A similar technology is used on the iPhone 7. Reviews of the Samsung Galaxy S8 are positive, and users liked it.
The design of the Samsung Galaxy S8 is somewhat different from its counterparts. The first thing to notice is that there is no Samsung inscription above the screen. The company's engineers simply could not find a place for it. At the same time, the shape of the smartphone is unique, there are no analogues in terms of design on the market today. What makes the owner of the phone stand out from other smartphone users.
The flagship itself is made of glass and metal. You should be careful when using it. The device is not only slippery but also instantly covered in fingerprints. It is worth using wipes more often - this will keep your smartphone attractive throughout the day. The glass covers the entire front and back sides of the case. The frame is made of metal.
The model is presented simultaneously in several colors:
- ⦁ golden;
⦁ blue;
⦁ gray;
⦁ black
The speakers have disappeared from the back. The case itself is assembled as reliably as possible. But there is a small gap between the glass of the front panel and the metal frame. The nail does not go there. But dust easily gets in. This is especially unpleasant if the phone is in black. Contamination is immediately visible against a dark background.
There is a fingerprint sensor on the back cover - right next to the lens. Moreover, the latter is now made on the same level with the plane of the body. There is a heart rate monitor, as well as an analyzer of oxygen saturation of the user's body.
Smartphone is a good solution for sports people. It is possible to keep a training diary, to take measurements of your body in automatic mode. Stylish and expensive body will distinguish the owner of the S8 from other smartphone users.
Design and ergonomics
The curvature of the Samsung Galaxy S8 is very similar to the geometry of Note 7. But the model in question is small, it sits comfortably in the hand. Comparing the Samsung Galaxy S8 to its closest competitor, the iPhone 8, easily holds up in specs and looks. The dimensions of the model are relatively small:
- length - 148.9 mm;
- width - 68.1 mm;
- thickness - 8 mm.
Moreover, the weight is only 152 g. The model will look great both in a strong man's palm and in thin women's fingers. The device is universal. The geometry of the case and the location of the home button make it comfortable for everyone, regardless of finger length and palm width. The S8 doesn't feel big. The main reason for this is that it is slightly elongated compared to its counterparts with the same screen diagonal.
Thanks to good balancing, it is convenient to work with the phone, despite the sloping body, it does not slip. On the left side there is a "swing" that allows you to easily adjust the volume. There is also a dedicated key to launch the assistant for Bixby. It does not work in our country. But you can find a special application on Google Play that allows you to easily reassign a button to another action.
Display
The Samsung Galaxy S8's screen is the first thing that grabs attention. Moreover, developers and marketers have even come up with a special name for it - Infinity Display. The display occupies 97% of the front area of \u200b\u200bthe case, has a QHD + resolution (2,960 × 1,440 pixels). The installed screen is very high quality, there are no dots.
SuperAmoled matrices were used in the assembly. This is the latest generation, improved in comparison with those used in the Note 7 model. Significant changes have undergone an algorithm for automatic brightness control - depending on ambient lighting conditions. Experts have improved the AlwaysOn Display mode. Buttons placed on the screen are hidden when applications are running. The diagonal of the display is exactly 5.8 inches.
The Samsung Galaxy S8 uses technologies that were previously only used in the development of TVs. In addition, the phone itself constantly analyzes the image on the screen. There is not only an indicator of the amount of light, but also an RGB color analyzer. It independently, without user intervention, adjusts the screen tones in accordance with external conditions.
The use of Mobile HDR Premium technology should also be attributed to serious advantages over competitors. It was developed literally in 2017 specifically for devices that support 4K resolution. According to experts, the screen in the Galaxy S8 is the most technologically advanced in the world. Its main differences:
- automatic brightness adjustment sets 1000 candelas at maximum illumination - you can easily read even small text in sunlight;
- uses DCI-P3 Color - also used on 4K TVs;
- there are simultaneously 2 sensors analyzing the amount of light - on both front panels;
- night mode excludes the presence of blue in the glow spectrum - this allows you to avoid unnecessary excitement of the psyche;
- a separate circuit for working with Always On technology is built-in - which allows you to significantly save battery power.
Equipment
The delivery set contains a standard list of items:
- the smartphone itself;
- device for connecting to a 220 V electrical network for recharging the battery;
- paper clip - allows you to remove the tray for placing a SIM card in it;
- headset type AKG - wired type;
- special adapter - for connecting additional equipment - OTG;
- instruction.
The OTG cable deserves special attention. With its help, it is possible to connect various external devices to the smartphone. Including all kinds of information carriers. These are USB sticks, as well as other equipment. The AKG headset allows you to listen to music. It cannot boast of impressive sound. But for watching movies, video from the Internet is perfect. The device is delivered in a cardboard box.
Samsung Galaxy S8 specifications
Even a year after its release, the device is still relevant. Perhaps this is due to the characteristics of the Samsung Galaxy S8:
- CPU - Exynos 8895, 8 cores, 2.3 GHz frequency of each;
- built-in video accelerator - Mali-G71 MP20;
- rAM (RAM) - 4 GB;
- the amount of ROM (read-only memory) - 64 GB (several GB are deducted for installing the operating system).
It should be remembered that the model is produced for different markets with different technical characteristics. For example, the Chinese version comes with 6 GB of RAM instead of 4. In the US, the exclusive Samsung Galaxy S8 is being sold on the Snapdragon 835 processor. That is why some devices show better results in various synthetic tests.
Performance
Various software tests don't always show how fast the Samsung Galaxy S8 is. But it's worth noting that there is no gap between clicking on an application icon and launching it at all. Even in comparison with the S7 and Note 7, for which there have never been any complaints in terms of speed, the S8 seriously wins.
We should also highlight changes in terms of memory. The improvement can be seen already in the transition from UFS 2.0 to UFS 2.1. This can significantly reduce the time it takes to boot your smartphone. In addition, switching times between different applications are reduced to a minimum. The S8 was the first device from Samsung to be equipped with UFS 2.1 memory.
Among users of alternative devices, there is still a rumor about the slowness of the smartphones from Samsung. But such stereotypes are usually the result of installing a huge amount of third-party software on the device. Samsung Galaxy S8 review will give an idea of \u200b\u200bthe real performance of the device.
Cameras
Using the device to take pictures and record videos is appropriate - the Samsung Galaxy S8 camera is worthy of all praise. The frontal resolution is as much as 8 megapixels, while it is fast. The widest aperture is f / 1.7. Due to this, pictures can be taken bright and sharp even with a significant lack of light. There are many built-in effects.
It seems to many that the main camera with a resolution of 12 megapixels has remained the same. DualPixel technology is used. As with earlier models, the supplier is Sony. Separately, it is necessary to dwell on the increased system performance. Samsung Galaxy S8 photos are more saturated. The camera model has its own memory.
Due to this, the speed of work increases by an order of magnitude. There is also a comfortable mode called Burst Mode. Thanks to him, you can take several dozen pictures in a row. The high performance of the system allows the camera to focus faster, better work out complex scenes. This is especially noticeable in comparison with the Galaxy S7.
A photo
A feature of Samsung Galaxy S8 photography is the ability to form a panorama with an impressive 50.6 megapixels. Which makes the quality of the images fantastic.
High power LED flash will illuminate shadows and also make the subject more detailed in shadows.
Video
Shooting video on the Samsung Galaxy S8 is as good as the photo. There is the ability to shoot video up to Ultra HD resolution. Recording is carried out at 60 frames per second. There is electronic image stabilization. But only in Full HD mode. In night mode, the video will also delight the smartphone user. Dynamic range, vibrant colors, and a good high ISO range make shooting easy and fun.
Front-camera
The characteristics of the front camera in comparison with the external one cannot be called outstanding. But she offers quite an acceptable result. Perfect for filming yourself while traveling.
It is necessary to work carefully in rooms with insufficient lighting. It all depends on the amount of light and other factors.
Sound and quality of music playback
The Samsung Galaxy S8 sound deserves special attention. Since Samsung applies a completely new development to its smartphone. It continuously analyzes the actions performed by the user. For example, if the owner of the smartphone is talking on Skype, then the sound in the headphones is automatically increased. All frequencies, extraneous noise - which can interfere with communication are also cut off.
In addition, the smartphone constantly evaluates the sound level around the device itself. An automatic adjustment to the situation is carried out. Moreover, the sound processor does not carry out all these actions; only the amplifier is used to solve the assigned tasks.
Another "feature" of the model is the automatic recognition of repetitive sounds. For example, if the headphones constantly rub against clothes, skin, then the device tries to clean such noises from the music when listening to it. The sound quality depends on the headphones used, as well as the sound profiles that apply in a particular case.
Samsung has designed and assembled the included headset to match the specifications for the S8. All the delights of musical compositions are perfectly revealed thanks to the DSP Cirrus Logic SC43130. The main feature of the module is its versatility, it fits well with most headphones - without any exceptions.
Communication capabilities
As competitors, the Samsung Galaxy S8 supports USB Type C version 3.0. This is the first smartphone of its year of release where the latest generation Bluetooth protocol is present - 5.0. There is also aptX as well as other built-in audio codecs for audio playback. There is an LTE module, the frequencies used will depend on the specific operator, as well as the country of use of the device. Moreover, in the network of the LTE category, the device shows the maximum data download speed.
In the network on the territory of Moscow with the mobile operator MTS, the download speed reached 430 Mbit / s. Moreover, the theoretical limit of this indicator is only 450 Mbit / s. There is a dual-band Wi-Fi 802.11. There are no major improvements from Samsung in this direction.
operating system
At the time of the release of the device, the latest operating system was installed on it - Android 7.0. The proprietary Experiense 8.1 shell is installed on top. It functions quickly enough, there is a proprietary animation. It is somewhat similar to similar effects in Windows.
GPU fulfills all actions in the operating system as quickly as possible, without delays and "brakes", artifacts on the screen.
Autonomy
A standard Samsung Galaxy S8 battery has a capacity of 3,500 mAh. Charging can be done in two ways:
- via a standard USB Type C connector;
- using a wireless charger.
Moreover, in the second case, recharging is carried out automatically - you just need to place the device on a special wireless station. Several energy saving profiles should be noted separately. They became more aggressive. This saves battery power and extends the life of the device. For example, video playback time is 18-19 hours with maximum brightness.
Pros and cons of a smartphone
The Samsung Galaxy S8 has its own pros and cons. The main advantages include:
- elongated display - this makes it convenient to use;
- well-fitting details, bright screen;
- high-quality cameras, the ability to shoot video in Ultra HD resolution;
- comfortable interface and performance;
- notification indicator, dust and moisture protection;
- external speaker volume.
There are also obvious disadvantages. The Samsung Galaxy S8 smartphone is reviewed in detail in the review, the main disadvantages include:
- easily soiled case - fingerprints remain permanently;
- the back glass is highly prone to scratches;
- if you use a smartphone for games, the edge of the USB connector is constantly rubbing your finger;
- fragile design requires a case;
- lack of a convenient way to quickly unlock the device.
In general, all the disadvantages are easily offset by a large number of advantages. The device does an excellent job with all the functions assigned to it.
Comparison with competitors
The main competitor in this price category for the Samsung Galaxy S8 is the iPhone 8. Comparison of the device by the main parameters:
- the S8's display is 5.8 inches versus 4.7 for the iPhone 8. Samsung's product benefits not only in size, but in more advanced technology and resolution;
- in terms of performance, the Snapdragon 835 processor is one step lower than the A11 Bionic. Apple's developments in this industry are products of a completely different category (this is easily confirmed by the Geekbench test);
- the cameras of these devices give almost identical results. The Apple product has some advantage in brighter lighting;
- the wireless charging dock comes standard with Samsung products. For a product from Apple, you will need to purchase it separately;
- in terms of standalone mode, both devices will not let their users down. Samsung Galaxy S8 has 1 hour of active talk time longer.
In general, both devices will be a great solution. But it's worth remembering that there are differences in performance as well as functionality. It is important to consider the dramatic differences in operating systems.
Final review
Despite the fact that the Samsung Galaxy S8 was released relatively long ago (more than 1 year ago), it is still in high demand in stores. The reason for this is good performance, high-quality images and long battery life. It is worth remembering that the use of this device without a cover threatens the back glass with scratches. There are other nuances of operation.
The Samsung Galaxy S8 performs well regardless of the processor installed. The communication quality is at the highest level. The ability to work with Wi-Fi in two bands at the same time deserves special attention. Another advantage is that the cost of the model dropped significantly during the year after its release.
