Nokia x2 description. Nokia X2 - Specifications. Specifications NOKIA X2 DUAL SIM

A year ago, it was believed that it was impossible to combine Microsoft services and the Android operating system, but at the moment we can see the second generation of smartphones based on the Nokia X Platform. A distinctive characteristic of such mobile devices the lack of functionality of Google and Play services. The manufacturer's graphical shell has been added to the Android operating system. Unlike Windows Phone, the presented smartphone retains the ability to download a huge number of Android applications, their range compares favorably with other similar models. The Dual Sim communicator, the review of which we offer you, has a more powerful hardware base and an updated operating system compared to the first smartphones in this line.

Delivery overview

When talking about Dual Sim, user reviews will be invaluable to us in helping us achieve objectivity. The packing box is made of high-quality and dense cardboard, you can be sure of the safety of its contents. It contains an image of the smartphone, its name, the manufacturer's logo and information about the mobile device and the location of the company. The box is quite presentable and bright, capable of immediately attracting attention. The information sheet contains the name of the smartphone, its equipment, main technical characteristics and possible color options (for example, Nokia x2 Dual Sim Green). The packing box slides out to the side, after which we have access to the communicator and all related accessories. The smartphone comes with network adapter, stereo headset, and user manual. By the way, an important point about Dual Sim: reviews of many users call it a little strange the lack of a USB cable and memory card, which will have to be purchased separately.

Structure

As with all Nokia mobile devices, the side walls are soldered to the back cover and form a kind of rectangular box into which the device is placed and snaps into place for greater strength, durability, and guaranteed absence of gaps and squeaks. The Nokia X2 Dual Sim smartphone can be easily removed from the box if you need to change the SIM, battery or memory card. The design of the mobile device is very similar to the advertised Lumia, it is very recognizable and familiar to almost all users of communicators from this manufacturer. Distinctive features of the smartphone are bright colors and minimalistic rectangular shape. The manufacturer offers the model in several versions - light green, black or bright orange. It can be noted that the smartphone has become even more angular along the side edges, and the roundness on the back cover has completely disappeared. Compared to other glossy mobile devices, the Nokia X2 looks better thanks to its two-layer, vibrant color coating. Regular plastic on top is supplemented with a layer of transparent polycarbonate. This solution reliably protects the smartphone from scratches typical for a glossy case, and also gives the device a beautiful effect of depth. Instructions for dismantling the back cover are included in the user manual. You shouldn't have any difficulties with this process, you can even do without improvised means. Under the back cover there is a removable battery, slots for a memory card and two SIM.

Nokia X2 Dual Sim: display reviews

The screen has a protective and oleophobic layer to minimize fingerprints during use. Also, the device has an anti-reflective coating so that light sources do not distract from the work on the smartphone. and the glass is separated by a special plastic thin insert, now it does not protrude beyond the edges of the case and when placed on a hard surface of the smartphone with the screen down, you must be very careful not to damage the display. The top panel contains a speaker, a connector for a USB cable and a stereo headset. On the right side there is a volume rocker and a power button and a lock for a mobile device. The assembly of the smartphone was made very high quality, when you press on the screen, color stains do not appear, and when you rotate, nothing bends, and the geometry of the device remains unchanged.

Volume

Nokia X2 Dual Sim is an Android smartphone with only one multimedia speaker built in, and when the mobile device is placed on the front side, the sound can be muffled. The device is loud enough, but the negative side is the complete absence of low frequencies. The speaker is mainly intended for listening to music, playing games and watching movies.

Shooting

The mobile device has a resolution of 0.3 megapixels, and the main one has 5 megapixels. In the presence of optics with aperture, sensor, digital 4x zoom, auto focus and LED flash. You can get good pictures both during the day and at night. When shooting in a dark room or at night, be sure to turn on the flash. not impressive, poor results persist even when the settings are set to maximum and when the screen resolution is increased or decreased.

Conclusion

To create its new product, Nokia completely worked out past mistakes, improved the operating system, increased the performance of the smartphone and slightly changed the controls, while maintaining the bright youth design of the mobile device. For its price, the model turned out to be quite successful, there were no complaints about the rigidity of the structure, the quality of its assembly, color rendering, the work of the navigator, wireless interfaces, the speed of launching applications for the whole time. It should be said that reviews of the Nokia X2 Dual Sim are currently mostly positive.

What if you combine the Android operating system with Microsoft services? A year ago, such a combination seemed impossible, but now we see the second generation of phones based on Nokia X Platform. It is actually an Android operating system, but with Nokia's proprietary graphical shell, devoid of Google services, including Google Play. But the ability to install a huge number of Android applications remains, and their range compares favorably with that of Windows Phone. In addition new smartphone compares favorably with the device of the "first wave" as an updated OS and a more powerful hardware base. Whether these innovations are worth attention, we will find out in this review.

Delivery and equipment

The box in which the smartphone is delivered is small, which has already become familiar to nokia... It is made of thick cardboard, so you don't have to worry about the safety of the contents. Bright and high-quality printing is eye-catching. On one side, there is only an artistic photo of the device, while the opposite part is more informative.

Here you can find the name of the new item, the package bundle (in pictograms), four possible body colors and the main technical characteristics.

Sliding box: the inside slides out to the side, after which we get access to the contents. We found in the delivery set charger AC-20, Nokia Stereo Headset WH-108, User Guide and Warranty Card. The presence of a modest headset upset us less than the lack of a USB ↔ micro-USB cable, which will have to be purchased separately.

Appearance, design and arrangement of elements

The design of Nokia X2 Dual SIM is familiar and recognizable to all customers who have seen the Nokia Lumia series smartphones at least once. Minimalistic rectangular shapes and vibrant body colors are the hallmarks of these devices, and the novelty is no exception. Evil tongues can call the chosen color scheme "childish", but it certainly cannot be called dull. In this case, three color options are possible: black, bright orange and light green.

Taking Nokia X2 Dual SIM in hand, you can feel its angularity: the side edges have become much less rounded, and the roundness on the back cover has completely disappeared.

The novelty looks advantageous in comparison with other glossy devices due to its two-layer coating. The bottom layer of ordinary colored plastic is covered with an outer layer of transparent polycarbonate. This "sandwich" gives the body a depth effect and protects the colored part from scratches, which usually appear very quickly on a glossy painted surface.

The back panel is made as a single piece with sidewalls. Removal instructions are provided on the label. To remove the rear cover, press on the protruding corners from the front side. There were no difficulties with removal, while in the assembled state we did not find any backlashes or gaps: the lid sits like a glove. At the first meeting, it may even seem that it is not removable.

Under the removable panel, we found two Micro-SIM slots, a removable battery (Nokia BV-5S, 1800 mAh) and a slot for microSD memory cards.

The Nokia X2 Dual SIM screen has an oleophobic (grease-repellent) and protective layer, as well as a ClearBlack anti-glare coating. Thanks to them, fingerprints are easily erased (alas, they appear easily), and extraneous light sources distract less when working with the screen.

The speaker hole above the display tends to collect dust. Under the screen there are touch keys "Back" and "Home". The appearance of the latter was envisaged in latest version Nokia X Platform. It allows you to immediately return to the home screen without pressing "Back" several times. The manager of running applications is launched by long pressing the "Back" button. It allows you to close or switch to the application of interest by scrolling sideways.

As for the location of other key elements, the top panel houses a micro-USB port and a 3.5mm audio jack for connecting headphones. And on the right side, a volume rocker and a lock / off button are conveniently located.

Summing up our impressions of the construction, let's say that the Nokia X2 Dual SIM has a very rigid body with well-fitting parts. When twisted, the geometry of the smartphone does not change and nothing bends. When pressure is applied to the glass, colored streaks do not appear on the screen.

The screen does not break records in pixel density: with a diagonal of 4.3 inches, the resolution is "classic" 800 x 480 pixels, which gives us a density of 217 ppi. Here you can poke your finger at the Nokia XL Dual SIM smartphone, which at the same resolution had a diagonal even higher - 5 inches, and the density was only 187 ppi. In both cases, the indicators are not record-breaking and individual pixels can be seen without much visual strain. In the OS interface, low resolution is not as noticeable as when viewing user-generated content.

But the Nokia X2 Dual SIM screen has and strengths... These include a high-quality IPS matrix, correct color rendering (there is a shift in the color field to yellow and violet shades, but weak) and the absence of an air gap between the protective glass and the matrix (OGS technology), which improves image perception. The brightness is sufficient (there is auto adjustment), the contrast is good and the viewing angles are quite wide.

The touch layer handles up to five simultaneous clicks. It has good sensitivity, but in the cold season, gloves will still have to be removed. You can unlock your smartphone by double tapping the screen.

Sound

The Nokia X2 Dual SIM uses only one multimedia speaker, which is located at the bottom of the rear side, so the sound can be muffled if the novelty lies on soft surfaces with the screen facing up. The sound itself is quite loud. However, it almost completely lacks low frequencies, and the lower midrange is poorly represented. I was only pleased with the quality and detail high frequencies... In general, the multimedia speaker will be enough for undemanding users to watch videos and play games.

The speaker made a good impression: it provides high quality speech transmission with good detail. Yes, and there is a volume margin.

Nokia X2 Dual SIM installed front-camera with a resolution of 0.3 megapixels and a rear 5 megapixel. The main camera uses a ¼ inch sensor and f / 2.7 aperture optics. There is also autofocus, digital 4x zoom and LED flash.

Main camera provides snapshots good quality in favorable conditions. It is difficult to get an acceptable result in low light, but you can use the flash and still have reasonably accurate white balance. However, in daylight, using the flash adds a warm color to the frame. The detail is generally high, corresponding to a resolution of 5 megapixels, but the dynamic range is small, so some frames are overexposed. The video quality for the 2014 smartphone is not impressive at all. Setting the maximum settings and resolution (1280 x 720 pixels) does not improve the situation. The sound quality is consistent with the resulting video.

The front camera with a resolution of 640 x 480 pixels is not suitable for artistic shooting, but it copes with its basic functions. The very fact of its presence pleases me.

The camera application itself has rather modest functionality. It has useful shooting modes (Auto, Night, Sports), but no sensitivity or HDR settings.

Software

The Nokia X Platform 2.0 OS is the highlight of the Nokia X2 Dual SIM smartphone. In fact, it is Google Android 4.3 Jelly Bean OS, but Microsoft services have replaced Google services, and the graphical shell copies the usual tiled interface and methods as much as possible windows management Phone 8. The official Nokia Store still has a small number of available applications... But they can be installed manually: according to Nokia experts, about 75% of all android applications will work properly on these smartphones without any modifications. In addition, there are alternative app stores, for example, Yandex.Store.

The downside is the complete lack of services and google applications... It's not just about the Google Play store or navigation: even transferring contacts from account Gmail is not provided (contacts are entered manually).

I was pleased with the navigation of Nokia HERE Maps: it is convenient both to download maps to the device and to use them. The maps are detailed, so grieve the absence Google maps don't have to.

If there are controversial points in the functionality of the shell, then the speed of its operation does not cause any questions: there are no jerks or freezes, the animation is smooth and the response to user actions is fast.

Performance

The computational capabilities of the novelty are entrusted to dual core processor Qualcomm Snapdragon 200 (MSM8210) with integrated graphics core Adreno 302. It is based on a 28nm process technology (ARM Cortex-A7 design) and operates at a frequency of 1.2 GHz. The good news was the increase in volume random access memorywhich is now 1 GB. This value corresponds to a mid-range device, and it is quite enough for Nokia X2 Dual SIM.

The ROM is 4 GB. It can be expanded with a microSD card up to 32GB and store files on a free remote cloud storage volume of 7 GB.

Unfortunately, the new product has retained the disadvantage inherent in Nokia XL Dual SIM: the inability to install applications on removable media. They are installed only in the internal memory of the phone, which is reserved for the user's needs only 1.95 GB. This is more than that of its predecessor, but does not fundamentally change the situation. These restrictions prevent us from calling the Nokia X2 Dual SIM a great low-cost gaming smartphone.

The performance of the novelty has increased due to the use of a more productive processor and an increase in the amount of RAM, but the novelty is not very suitable for serious gaming applications. Note that the speed of reaction to user actions in the OS and ordinary applications is quite high and does not cause any irritation.

Communication and communications

As we mentioned above, Nokia X2 Dual SIM has two slots for installing SIM-cards of the Micro-SIM format, which can be accessed only after removing the back cover. At the same time, SIM1 installation is possible only after removing the battery, but the card in the SIM2 slot is much easier to change.

The novelty uses only one radio module, that is, the smartphone operates in the " Dual Standby SIM ". This means that both cards are available in standby mode, but making a call from one of them automatically disables access to the other. After the call ends, both cards will be available again.

For high-speed data transfer, the tested model has 802.11 b / g / n Wi-Fi and Bluetooth 4.0 modules. Working with wireless networks goes smoothly: the connection is established quickly and keeps up well.

The navigation module supports GPS, GLONASS and Beidou positioning systems. Going out into the open, we were able to catch more than 20 satellites and connect to at least half of them. The connection process took place quickly: according to our measurements, no more than 10 seconds.

Autonomous work

The Nokia X2 Dual SIM smartphone is not burdened with an excessive number of cores and many gigabytes of RAM, coupled with a gluttonous large screen, so the Nokia BV-5S battery does its job well. Under everyday (by our standards) load, the 1800 mAh battery provides up to two days of operation.

Test results: viewing HD video at half the brightness of the display and the wi-Fi modules and GPS - a little over 6.5 hours (6:45); simulate gaming load using Epic Citadel app (Guided Tour mode) with maximum display brightness and enabled Wi-Fi and GPS - 3.5 hours. The estimated runtime according to the GFXBench benchmark was 260 minutes.

Charging time of the battery from the included 3.75 W AC-20 adapter (5 V @ 0.75 A) is approximately 2.5 hours.

Outcome

Summing up, I would like to abandon the clichés, but still let's say that the epithets "fashionable" and "youthful" are quite applicable to. The company has worked on bugs, increasing the performance of the smartphone, finalizing the OS and controls, while maintaining a striking design.

However, some important, in our opinion, shortcomings are still preserved. For example, the impossibility of installing applications on a memory card, which can alienate fans to play "weighty" toys from the novelty: two modern blockbusters will easily eat up all the free space on internal storage... There is also a problem with a relatively small number of additional applications in the official store, but this is more a question for software developers.

In general, the Nokia X2 Dual SIM phone turned out to be successful for its money. We had no complaints about the build quality of the case and the rigidity of the structure, the color rendering of the IPS-screen, the quality of voice transmission, the operation of wireless interfaces and navigation, the speed of drawing the interface and launching applications. There are questions for the camera, especially in terms of video shooting, but this quality is enough for everyday use.

As a result, Nokia X2 Dual SIM has become a strong middling, almost getting rid of the "childhood diseases" of the first version of Nokia X Platform. It can be advised to buy unassuming buyers who just need a pretty and moderately productive smartphone for every day, or those who like to “work with a file”, who will have a lot of room for creativity and personalization.

Advantages:

• nice and stylish appearance;
• high build quality;
• two slots for SIM-cards;
• the ability to install Android applications;
• high-quality color reproduction, brightness and contrast of the IPS-screen;
• the presence of an oleophobic coating of the screen, anti-reflective filter and protective glass;
• good quality of the images obtained from the main camera in good lighting;
• high speed of the OS interface and undemanding applications;
• high-quality conversational speaker;

Nokia of the Android "X" line is evolving - the X2 model has become even more similar to Windows Phone than its predecessor - the X model. But at the same time, it has become closer to Android - now there are two buttons under the screen - "back" and "home", and not strange lonely "back" as before. Let's see how the Finnish manufacturer is trying to attract those who dream of "Android with an interface like WindowsFon"!

Nokia X2 Dual SIM :: Review :: Design and features

X2 is another "phone in a box", its back cover is combined with the side walls, forming a "box" into which the phone itself is put and snapped on. This system has been used by a Finnish manufacturer for more than one year, and has been polished to perfection - a smartphone in this design is durable, monolithic, does not emit squeaks, and at the same time it can be easily removed to replace a SIM card, memory or battery - without broken nails and various kinds of application auxiliary gizmos, as it once was. "Box" X-Second is made of two layers - colored plastic is covered with a transparent layer. The result is a stylish "floating" effect, a la amber, looks interesting together with bright colors - acidic green, orange and yellow. Classic black and white are also available in colors, but they do not look so extravagant.

The X2 is an inexpensive model, so no special efforts were made to make the case thinner, and the bezels around the display - narrower ... The bezels are obviously too big - especially at the bottom, where the buttons are located under the screen. By the way, there are now two buttons, and not one, as on the previous Nokia X (there was only a back button in the form of a checkmark lying on its side). In the X2, it has been supplemented by the home button familiar on any smartphone, which leads to the main screen. The buttons are touch-sensitive, but, unfortunately, no backlight.

The rest of the device is quite traditional - the volume and power buttons are located on the right side, the headphone and microUSB jacks are on the top, the left and bottom are empty.

The back panel has a large opening for a camera (like a solid camera phone!), An LED flash and a speaker cutout. Interestingly, the speaker slot does not have pimples-"legs", which create a gap when the phone is lying on a smooth surface (so that the sound does not shut up), but there is no need for them - even on the table with the display upward, the bell sounds loudly!

Removing the filling from the case - a training sticker is pasted on the back cover:

Cover - "box"

The insides of the apparatus:

The glossy plastic is beautiful, and in vibrant colors, it doesn't tend to accumulate prints (cool!), But slippery. Taking a smartphone off the table with dry fingers is sometimes difficult - it strives to slip out!

Nokia X2 Dual SIM :: Review :: Display

The screen of Nokia X2 is not bad, but miracles should not be expected - it corresponds to the moderate price of a budget gadget. If someone in 2014 forgot what a single pixel looks like - great, you can take a look! :) In X2, the points that make up the image are clearly visible to the naked eye, because they are large and their number is small. 480x800 pixels on a large 4.3-inch screen is only 217 pixels per inch (PPI), which is really not enough in today's times.

At the same time, low-pixelity is harmoniously compensated for by the excellent brightness and richness of the IPS-matrix with wide viewing angles, which works in conjunction with the proprietary Nokia ClearBlack technology - the polarizing layer gives a high-quality (although not Amoledov, of course!) Black color, and removes glare, and the ClearBlack software controls the contrast based on the light sensor signal. The X2 display is unlocked not only by pressing power buttons, but also by proprietary Nokiev double tapping on the screen.

Nokia X2 Dual SIM :: Review :: operating system

The “X” line of “hybrid” smartphones is not yet well known, and most of the technically savvy acquaintances I interviewed were unable to explain the essence of the Nokia X operating system, its interface and the application ecosystem ...

Therefore, we will explain what will have to be explained, I think, in more than one review - Nokia X is a clever "nodding" towards the supporters of Android smartphones, the compromise to which the consortium Nokia and Microsoft decided to "move" without changing the fundamental positions of the line Lumia and windows systems Phone. Actually, "xOS" is a proprietary Nokia trick that allows you to bite off a piece of the "world android pie", while ... distancing itself from it and "saving face." It seems to be Android, but it seems not ... This move is a double-edged sword, because until now most people believe that today "there is no Android on Noki - there is Windows Phone and some other operating system of its own." Who is right and to what extent?

First you need to understand the main thing - the look and interface of any operating system is not a dogma. On top of the operating system, you can install so-called "shells" that can radically change the appearance and even the algorithms for use. There are and are written many shells - with their help it is easy to make an "iPhone" from an android smartphone (only visually, of course!), Or from Linux - Windows (again, only in the sense of an interface, not an entity!). The same is done in the Nokia X-series smartphones. The system properties say "Platform version - Nokia X software platform 2.0", but in fact it is a shell based on Android 4.3. But visually, it very closely copies the "Metro" interface, which is characteristic of Windows Phone.

The main internal difference is the absence of all proprietary Google services, Microsoft's ideological rival. Maps, mail, Google social networking projects, built-in google search everywhere, etc. - this is not. At the same time, there are no significant inconveniences - the Google page quietly opens in the browser, clients of any social networks are downloaded from the App Store, instead of online Google maps, a hundred times cooler Nokia maps that work without the Internet are built in, etc.

Nokia X2 Dual SIM :: Review :: App Store

There is no Google Play store in X2, but it is, in essence, a game of formalities. PlayMarket has not been the only source of programs for android smartphones for a long time, applications have long since spread among many "second-hand dealers", in terms of trade. Nokia X has just a Store (Nokia's own bank of applications, with programs selected by the manufacturer), Yandex.Store, where there are hundreds of thousands of them, and you can also install other alternative stores! Almost any application available on PlayMarket can be obtained on Nokia X (with rare exceptions). And what is traditionally free will remain free, regardless of the download source. The only inconvenience is that to search for this or that not very common program, you will have to rummage in two or three or four stores, and not in one, as in the case of PlayMarket in ordinary android smartphones. However, when it comes to the most popular programs - social network clients, games, browsers, players, file managers etc. then they are on the first pages in ANY markets - in the regular, and in "Yandex", and in others.

Both the regular Store and Yandex.Store have dozens of different Twitter clients. But only Yandex.Store has an original Twitter client not from third-party developers, but from the microblogging network itself - it is not in the Nokiev store:

However, it must be admitted that with quite successfully filled app stores, there are still less programs in the Nokia and Yandex stores than in Google Play! And the situation in which your friend / colleague with an ordinary android smartphone will launch some application or game, and you simply will not find it in any of the markets with Nokia X2 is quite real.

Nokia X2 Dual SIM :: Review :: Interface and menu

The first Nokia model from the X-line was only vaguely similar to Windows Phone, and it was not particularly convenient to call it. All applications are on the main screen, a single "back" button, etc. X2 really practically copies windows interface Phone - it consists of three working screens that change horizontally.

In the center is the main home screen, on which icons-tiles of frequently used applications are placed. There you can arrange them in a convenient order, group them into folders, change the size and color of the icons.

To the left of the main screen, there is a secondary screen "Recent", which displays everything that happens to the phone - messages about missed calls and received SMS and letters, about installing new applications and updates, etc. appear on it.

To the right of the main screen is the screen where ALL installed applications, endless sausage, no grouping - only in alphabetical order. From this screen, applications can be launched, removed from the phone, or added to the home screen.

Three home screens together:

In "X", like any "android", swiping your finger across the screen from top to bottom brings up the quick adjustments panel - wireless networks, brightness, etc. The latest notifications are also displayed there, as on the "Recent" screen.

Pressing and holding the Back button brings up a list of recently launched applications, from where they can be called up again or forced to close.

Apps installed by default out of the box. There are not so many of them, and there are no unusual or cool paid ones among them. But due to the "Windows Phone" location in the endless sausage, to view them, you need to scroll the screen a dozen times, which creates the illusion of a huge number of them ...

Nokia X2 Dual SIM :: Review :: Main functions

Call service. Dual-SIM functionality is implemented traditionally for most modern smartphones. You can see contacts from both SIM cards, you can bind certain contacts to a specific number, when you call the device prompts you to select the required SIM card.

Mail. Universal mail client - There is no Gmail client in Nokia X2, like other Google services.

File manager. There is no full-time manager - the well-known Astro is preinstalled as it - in the free version with advertising. You can install any other.

Music and radio. The three apps are Music Player, FM Radio and MixRadio. With the first two, everything is clear, and with the third ... everything is also clear, but only to those who know about this proprietary Nokia application. MixRadio is a music store, which is interesting because, in addition to buying albums and songs for cash, it allows you to download collections of thematic mixes via Wi-Fi or 3G for free and listen to them offline at any time.

Gallery. The Gallery application is responsible for photos and videos. Everything is in order with the photo, but the video is so-so ... Support for a mass of popular container formats is declared - AVI, Matroska, MP4, etc., but there is no real omnivorousness. MKV starts up, but it slows down terribly, other videos play sound, but no video, or vice versa ... Like many androids, you will need to install a bunch of different players from the Markets, and experiment with them ...

Browser. Not too comfortable. Displaying the page is possible in both portrait and landscape orientations, but at the same time, if you bring up all open pages from landscape orientation, the screen is forced to turn to portrait ... The installation of Opera suggests itself.

HERE navigation. The famous Nokiev navigation. Classics and perfection! There are no complaints here - maps of all countries of the world, car and pedestrian voice navigation, a lot of different services and goodies.

Nokia X2 Dual SIM :: Review :: Camera

Nokia X2 is not a camera phone. His camera is designed only for light shooting conditions, it works slowly, it makes a terrible noise at dusk. There is no separate button to release the shutter. In general, for decent photography you need something more solid ...

But the camera interface is nowhere easier! In the basic version, it does not bother the user with unnecessary settings - there are only TWO icons on the screen - a shutter button and a button that changes the flash mode.

If you touch the arrow that hides everything else, then the mode switch ("auto", "night" and "sports"), the change of cameras and the gear icon leading to the settings, which, in general, are also few, open.

Nokia X2 Dual SIM :: Review :: Performance and nutrition

The Nokia X2 processor is a typical budget "stone" - a 2-core Qualcomm Snapdragon 200 (MSM8210) 1200 MHz, Adreno 302 video core. (True, AnTuTu Benchmark defines it as MSM8610 and Adreno 305)

The same AnTuTu characterizes the smartphone's hardware as weak:

However, what did you want for this money ?! The device is positioned as affordable - it is naive to demand records from it. At the same time, the interface really flies, no complaints. Most application applications run quickly and smoothly.

The gadget is powered by a modest 1800 mAh battery. This is not enough - the younger model Nokia X had a 1500 mAh battery and worked on it for one day - in this case, there are fears that history will repeat itself, and the positive difference between the battery capacity will be absorbed by the positive difference in the diagonal of the screens ...

Let's conduct a simple and visual test, which I traditionally use to assess the efficiency of battery use - we charge the battery 100%, reboot the device to clear the memory of clogging programs, turn off everything wireless interfaces, except for cellular communication, set the screen brightness and volume to maximum. We launch a movie in AVI format, which lasts 1 hour 23 minutes and weighs 1.45 GB. After completing the film, we look at the remaining battery charge.

The prediction almost came true. Nokia X in a similar experiment saved 60% of the battery charge, which is very little, X2 - 64%, which is slightly more. Today, even budget devices after such a test remain with 70-75% of the energy, and the flagships with their powerful batteries and with a bunch of energy-saving technologies they save 80-85% at all! Alas, in terms of longevity, the device is a one-diary.

Nokia X2 Dual SIM :: Review :: Impressions and conclusions

At a cost of 6,000 rubles, Nokia X2 dual sim looks quite competitive in comparison with budget “androids” of other leading brands. Of the physical advantages - a strong construct, a catchy unusual appearance in "acid" versions, a bright and juicy display, loud sound, two SIM cards. The X2 is based on an inexpensive dual-core chip, but with a gigabyte of RAM, the gadget is vigorous and nimble, although not intended for flagship games. Of the software, the free navigation HERE traditionally pleases, the interface is original, but very easy to learn. Among the shortcomings - the practically absent built-in memory (with the aforementioned 4 GB, in reality it is less than two), a rather weak camera, a large body for a 4.3-inch display (it would be nice to make it either smaller, or, with the same dimensions, fit 4 into it, 7-inch screen).

Slightly grown up and improved version of the "smartphone for Android applications"

A big change swept through Microsoft's mobile division this summer. Nokia has done away with the budget Asha line. The software giant has ditched the ambitious McLaren project. And the Nokia X line was decided to be transferred to the Windows Phone OS, ending all relations with the Android platform. But a little earlier, the manufacturer managed to present the second generation of these smartphones, which we will discuss in today's review.

Nokia X2 offers

* - at the time of this writing

The second model Nokia X no longer looks "gnawed" from all sides. The amount of RAM increased to a comfortable gigabyte, a front camera and flash appeared, and a more powerful SoC was installed. But the price has also increased, and by a noticeable amount for the budget segment.

Equipment

The Nokia X2 comes with the same set of accessories as its predecessor. Only the headphones have been repainted in regular black. "Bright Nokia X2" did not benefit from this.

By the way, the headset does not have a button for receiving a call, so you will have to take your smartphone out of your pocket when you call. The cable for connecting to the PC is still missing.

Design

Externally, Nokia X2 is not much different from its predecessor. At first glance, only the additional Home button under the display catches the eye, moving the Back button to the left.

The main design feature of Nokia X2 is a two-layer body, made using the same technology as in Nokia Asha 500/502/503. The bottom layer is made of colored polycarbonate. The upper one is made of an almost transparent polymer material, slightly tinted in the color of the lower layer.

The original Nokia X looked like a toy, largely due to the ingenious plastic body. The second generation turned out to be much more interesting in this regard.

Phones with a two-layer case are not common on the market, which allows Nokia X2 to win next to discreet neighbors in the store window due to its originality.

The rear speaker is now centered. The flash is positioned above the camera.

A closer examination of the lens and flash shows that the back cover does not fit well with the main body of the smartphone.

The mechanical buttons have hardly changed, only the volume rocker is now split by a slot.

The Micro-USB connector has been moved from the bottom to the top, towards the headphone output. The 3.5mm jack is moved down, but its hole is covered by the outer shell. The rest of the smartphone functional elements deprived.

To open the smartphone, you need to press on the lower corners of the case and at the same time on the back panel, just like in Nokia X. After a few such manipulations, the colored cover starts to fit loosely and play around the lower left corner - previous model in this regard it was more reliable.

Access to SIM1 and microSD is possible only with the battery removed. Please note that the sticker of the first model read "Nokia", and here - "Microsoft Mobile".

The slot of the second SIM-card is located so that it can be accessible while the smartphone is working. The hot swap function works perfectly here, the card is quickly detected by the phone on the go without rebooting. Another nice improvement in the series.

The build quality of the Nokia X2 is inferior to the original. It is worth removing the back cover five or six times, and it already begins to fit loosely to the body, which can sometimes be heard even by ear. In general, the second version of the smartphone became more interesting both from an aesthetic and functional point of view, but there were no fundamental changes. Perhaps we will see more daring design moves with the transition of the series to Windows.

Screen

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 anti-glare properties of the screen are not worse than those of the screenGoogle 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 of both devices (Nokia X2 is on the right, then they can be distinguished by their size):

The screen of the Nokia X2 is even slightly darker (brightness in the photos is 99 versus 101 for the Nexus 7). The tripling of reflected objects in the Nokia X2 screen is very weak, which indicates that there is no air gap between the outer glass (aka touch sensor) and the matrix surface ( screen type OGS - One Glass Solution). Due to the smaller number of boundaries (such as glass-air) with greatly different refractive indices, such screens look better in conditions of strong ambient light, but their repair in the case of cracked outer glass is much more expensive, since the entire screen has to be changed. On the outside of the screen, there seems to be a special oleophobic (grease-repellent) coating, but its effectiveness is low, so fingerprints appear quickly and require relatively much effort to remove.

With manual brightness control, its maximum value was about 455 cd / m², and the minimum is 9 cd / m²... The maximum brightness is high, and given the good anti-glare properties, the screen should be clearly visible in bright daylight. In complete darkness, the brightness can be lowered to a comfortable level. Automatic adjustment there is no brightness on the light sensor. The sensor between the front speaker and the camera can be mistaken for light-sensitive, but CPU-Z shows that it is a proximity sensor.

At any brightness level, the backlight is modulated by rectangular pulses with an amplitude of 100% and a frequency of 300 Hz. At high brightness, the fill factor is high, almost 100%, so there is no screen flickering, when the brightness is lowered, the fill factor decreases, and you can already notice the flicker, for example, when the eyes (or the phone relative to the eyes) move quickly. Depending on the individual, this modulation can lead to increased fatigue. Or it may not.

This screen uses matrix type IPS... The micrographs show the typical IPS sub-pixel structure:

For comparison, you can see the gallery of photomicrographs of screens used in mobile technology.

The screen has good viewing angles without a significant color shift even with large gaze deviations from the perpendicular to the screen and without inverting (except for the darkest shades when gaze deviates along one diagonal). For comparison, here is a photo in which the screens of Nexus 7 and Nokia X2 display the same images, while the brightness of the screens was initially set to about 200 cd / m² (across the white field across the entire screen), and the color balance on the camera was forcibly switched to 6500 K. White field perpendicular to the plane of the screens:

Note the acceptable uniformity of brightness and color tone of the white field. And the test picture:

Color reproduction is good and colors are saturated on both screens, but the color balance is slightly different. Now at an angle of approximately 45 ° to the plane and to the side of the screen:

It can be seen that the colors have not changed much on both screens, but in Nokia X2 the contrast has decreased to a greater extent due to a greater decrease in brightness and strong highlighting of black, and there is clearly added blue. And a white box:

The brightness at an angle of both screens has noticeably decreased (at least 5 times, based on the difference in exposure), but in the case of Nokia X2 the drop in brightness is much greater. The color tone of the white field on the Nokia X2 screen has changed somewhat. When deviated diagonally, the black field is lightened strongly (especially taking into account the general drop in image brightness) and acquires a violet or red-violet tint. The photos below demonstrate this (the brightness of the white areas in the direction perpendicular to the plane of the screens is the same for the screens):

And from a different angle:

With a perpendicular view, the uniformity of the black field is mediocre, since in several places along the edge the black is noticeably lightened, and the entire screen is in some spots in area:

Contrast (approximately in the center of the screen) is normal - about 700: 1. The response time for the transition black-white-black is 21 ms (10 ms on + 11 ms off). The transition between gray tones of 25% and 75% (based on the numerical value of the color) and back takes 32 ms in total. The gamma curve, plotted using 32 points with equal intervals by the numerical value of the shade of gray, did not reveal a blockage either in highlights or in shadows, and the indicator of the approximating power function it turned out to be 2.15, which is insignificantly lower than the standard value of 2.2, while the real gamma curve deviates little from the power dependence:

The color gamut differs slightly from sRGB:

The spectra show that the matrix filters moderately mix the components together:

At the same time, the coordinates of red and green colors are not very far from the corresponding vertices of sRGB, as a result, the colors of images - drawings, photographs and films - oriented to the sRGB space (and there are an overwhelming majority of them) have natural saturation and hue. The balance of shades on the gray scale is not ideal, since the color temperature is not much higher than the standard 6500 K, however, the deviation from the spectrum of a black body (ΔE) is greater than 10 (due to the excess of green), which is considered not a very good indicator even for a consumer device. However, the variation in color temperature and ΔE is small, which has a positive effect on the visual perception of color balance. The dark areas of the gray scale can be ignored, since the color balance there does not really matter, and the error in measuring the color characteristics at low brightness is large.

Let's summarize. The screen has sufficiently high maximum brightness and has good anti-reflective 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 level. However, the brightness will have to be adjusted manually, since there is no automatic brightness adjustment mode. The advantages of the screen include the absence of an air gap in the layers of the screen, a color gamut close to sRGB and a good - in visual assessment - color balance. The disadvantages - weak oleophobic coating, poor black stability to gaze deviation from the perpendicular to the plane of the screen, rapid drop in image brightness when viewed from an angle, not very good uniformity of the black field... We also note the PWM brightness control with a frequency of 300 Hz, which can also be a disadvantage in case of individual intolerance. In general, the quality of the screen is a compromise, although not to say that it is bad.

Sound

The rear speaker in Nokia X2 seems to have been only slightly shifted, and this is where the innovations ended. The listening experience remained about the same as in the first model. Sound quality meets expectations from budget smartphones. No distortion appears at maximum volume.

As for the conversational dynamics, here some progress is noticeable. Nokia X2 no longer suffers from timbre distortions. But you shouldn't dream of crystal clear communication, which is characteristic of flagships.

You cannot record a conversation using a smartphone. There is an FM radio, which requires headphones to work.

Telephone part and communications

Nokia X2 is equipped with two Micro-SIM slots, one of which supports the hot-swap function, which does not require rebooting the smartphone. Any of the cards can be assigned for data transmission, in this regard they are equivalent. Collaboration organized in Dual Standby mode - both SIM-cards are available in standby mode.

Wi-Fi 802.11 b / g / n is supported and the creation of an access point via Wi-Fi, USB and Bluetooth. Navigation in Nokia X2 works perfectly, in less than a minute it detects many satellites, not only GPS and Glonass, but also chinese system Beidou. And immediately contacts them.

USB OTG is not supported by the smartphone, but a small amount of memory can be expanded using microSD. Out of 4 GB internal memory 2.25 GB available. Turning on the smartphone takes 50 seconds, which is much more than the average.

Camera

Nokia X2 has stepped far forward in the possibilities of capturing photos and videos. The original model had a single 3MP camera. In the second version of the smartphone, it has grown to 5 megapixels and acquired a flash. In addition, a 0.3 MP front camera appeared.

The main camera was commented on by Anton Soloviev:

	Sharpness according to plans is not bad.
	Shumodav processes noise only in weak shadows. In the strong, they are noticeable, but not striking.
	Despite some noise, the color of the sky is fairly even.
	On the right, you can see the area of \u200b\u200bblur.
	The number of the nearest car is distinguishable, but more distant numbers are already impossible to make out.
	Sharping on wires is practically absent.
	The camera copes well with macro photography.
	The camera does a good job of writing, but not all characters are clearly legible.

For its 5 megapixel camera, the camera is not so bad, although it has a lot of problems. Shumodav tries to work as accurately as possible, and as a result, practically does not produce visible improvements. On the other hand, the sensor makes a rather "soft" noise, and the noise is not striking. The optics in the camera are quite good. In some places, for some reason, there are areas of confusion, but in general the pictures are quite sharp across the field and according to plans. In this case, the optics can work out more than the sensor can perceive. Nevertheless, the camera is quite good, but it does not work at all smoothly and will not cope with all the scenes. But shooting large text or general plans is within her power.

The maximum video resolution that the Nokia X2 camera is capable of is 1280 × 720.

The video is not very clear due to the low bit rate. However, if you remember that Nokia X shot a maximum of 352 × 288, progress is evident.

Software

Nokia X2 runs on Nokia X2 2.0 operating system (apparently based on Android 4.3). It differs from the original OS installed in Nokia X only in appearance. The structure of the system has remained unchanged. The main screen contains application shortcuts in the form of tiles, just like in Windows. Swiping to the left opens the list of all applications, and swiping to the right opens the Fastlane alert feed. The operating system works, in general, is stable, but sometimes the interface lags, especially when switching between applications and when setting up the desktop

Nokia and Yandex branded stores are available to install applications. There is no Play Store. Moreover, you won't even be able to add a Google account to import contacts and other information. It is not difficult to fix this.

It is easy to pre-install the driver and obtain Root rights through the utility. During installation, a request or two from the application will pop up on the phone - confirm them. Through Nokia X2 Tools you can install and Play Market... But in our case, it had a serious drawback: the program did not link purchases to the account. Therefore, we used an alternative method.

Play Market is installed in much the same way as google services in Ramos i10 Pro. You just need to copy all three files, including Vending.apk. And take them out of it. After copying and changing permissions, restart your smartphone. Play Market is installed.

AT new version Nokia's X OS is even closer to the original Android. Now, by shifting from above, you can call up two separate menus, with notifications and switches. This slightly expands the functionality, more icons are placed than before

The Achilles' heel of the Nokia X was surfing the internet, which is the very slow rendering of web pages. The second version of the smartphone is installed as standard opera browser... We've browsed a lot of web pages through it and Chrome. The impressions turned out to be much more pleasant, only in rare cases the drawing lagged behind by a split second, and even then on very loaded sites.

Performance

For the second generation Nokia X, Qualcomm's SoC was also chosen. From the base series of the next generation - Qualcomm Snapdragon S200, model MSM8210.

The central processing unit consists of two Cortex-A7 cores (ARMv7-A architecture) with a frequency of 1.2 GHz. For graphics, the Adreno 302 chip is used. The configuration is quite budgetary, you shouldn't have expected more from Nokia X2. Fortunately, the manufacturer has expanded the amount of RAM to one gigabyte, which cannot but affect the performance in a favorable way.

The increase in performance allows the Snapdragon 200 to easily outperform the Antutu 4 Mediatek MT6572, which is very common in budget smartphones. The previous Nokia X was not capable of this. And for Geekbench 3, there is not much difference: both SoCs have processor cores with the same characteristics. It's strange that twice the amount of RAM was not taken into account.

	Nokia X2 (Qualcomm Snapdragon 200)	Nokia X (Qualcomm Snapdragon S4 Play)	Explay Atom (Mediatek MT6572)	Oppo Muse R821 (Mediatek MT6572)
3DMark Ice Storm (more is better)	4094	2338	1882	1905
3DMark Ice Storm Extreme (bigger is better)	2252	1296	812	939
3DMark Ice Storm Unlimited (more is better)	3710	2245	—	—
Nenamark 2	53.0 fps	32.3 fps	41.9 fps	—
Basemark X Middle Quality (more is better)	3682	—	—	—
Bonsai benchmark	1634 (23.3 fps)	823 (11.7 fps)	—	—
Epic Citadel High Quality	42.9 fps	23.4 fps	—	—
Epic Citadel Ultra High Quality	32.3 fps	—	—	—

In synthetic 3DMark, the superiority over MT6572 becomes more than twofold. Even in the most demanding Epic Citadel mode, the Snapdragon 200 SoC demonstrates a decent result

Through the efforts of Google Chrome, the Snapdragon 200 SoC beats the same Mediatek. Based on the hardware capabilities, Nokia X2 could swing at average games, but the very small amount of internal memory does not allow it. It is worth installing several third party applications to fill in the gaps of the firmware, and, for example, far from the heaviest Asphalt 8 will complain about lack of memory. Fans of the X series continue to get only casual entertainment.

Video playback

We did not find the MHL interface, like Mobility DisplayPort, in this smartphone, so we had to limit ourselves to testing the output of video files on the screen of the device itself. For this, we used a set of test files with an arrow and a rectangle moving one division per frame (see "Testing methods for video playback and display devices. Version 1 (for mobile devices)"). Screenshots with an exposure of 1 s helped to determine the nature of the frame output of video files with different parameters: the resolution varied (1280 × 720 (720p) and 1920 × 1080 (1080p) pixels) and the frame rate (24, 25, 30, 50 and 60 frames / from). In our tests, we used a stock video player. The test results are summarized in the table:

Note: If both columns Uniformity and Skips green marks are set, this means that, most likely, when watching movies, artifacts caused by uneven alternation and skipping of frames will either not be visible at all, or their number and visibility will not affect the viewing comfort. Red marks indicate possible problemsrelated to playback of the respective files.

If we restrict ourselves to the typical 24-25 fps for cinema, then according to the criterion of frame output, the quality of video playback on the screen of the smartphone itself is good, since frames (or groups of frames) can be displayed with a more or less uniform alternation of intervals and without frame drops. The displayed brightness range is equal to the standard range of 16-235, that is, in the shadows and in the highlights, all gradations of hue are displayed in the case of normal video files.

Let's try to play five files of common formats.

Format	Container, video, sound	MX Video Player	Native video player
DVDRip	AVI, XviD 720 × 400 2200 Kbps, MP3 + AC3	reproduced normally	reproduced normally, no subtitles
Web-DL SD	AVI, XviD 720 × 400 1400 Kbps, MP3 + AC3	reproduced normally	reproduced normally, no subtitles
Web-DL HD	MKV, H.264 1280 × 720 3000Kbps, AC3	reproduced normally	played without sound
BDRip 720p	MKV, H.264 1280 × 720 4000 Kbps, AC3	reproduced normally	played without sound
BDRip 1080p	MKV, H.264 1920 × 1080 8000Kbps, AC3	reproduced normally	played without sound

The new budget platform Nokia X2 works well with all five common formats, whereas its predecessor could not even cope with 720p. Hardware decoding of AC3 tracks is not supported.

Battery life

The Nokia X2 has a 1800 mAh battery. The developers did not reach the round value, but this is already better than the modest 1500 mAh in the first modification.

The battery consumption is not uniform throughout the entire discharge period; when calculating, it is worth adding about 6% of the time that the smartphone keeps on the last percent.

	Battery capacity	Reading mode	Video mode	3D Game Mode
Nokia X2	1800 mAh	12 h 40 min	7 h 45 min	4 h 25 min
Nokia X	1500 mAh	14 h 15 min	6 h. 50 min.	3 h 50 min
Explay Atom	2000 mAh	9 h 50 min	5 h 40 min	—
Oppo Muse R821	1700 mAh	20 h 30 min	10 h 30 min	—
Oppo Mirror R819	2000 mAh	10 h 20 min	8 h 20 min	5 h 00 min
Fly Luminor IQ453	2000 mAh	10 h 00 mins	7 h 00 mins	4 h 10 min
Alcatel OT Idol X	2000 mAh	10 h 00 mins	6 h 40 min	4 h 00 mins

The autonomy of Nokia X2 has become more balanced compared to its predecessor. The smartphone lasts less in reading mode, but it still does not yield to most competitors. On the other hand, a more powerful SoC consumes more efficiently in more loaded modes, allowing you to increase battery life in games and video playback. Charging a smartphone from the included adapter (5 V, 0.75 A) takes about four hours.

Conclusion

The Nokia X line continues to evolve. In the second version of the device, the functionality was expanded, the stability improved, and some annoying problems were fixed. Nokia X2 could easily compete on all fronts with more unsightly budget smartphones, but this is difficult due to the increased price. The list of competitive advantages of the device still includes the original design, although the deterioration in build quality spoiled the impression. Hopefully, the third version of the Nokia X will increase the flash storage to a viable 8GB, leaving Windows Mobile with something for the modest needs of the user.
