Calibrating the screen android w3bsit3-dns.com. Calibrate the screen on android using phone settings or third-party applications. Calibration Quality Assessment Using Web Services

Very often, users of devices running Android OS are faced with problems associated with unstable operation of the sensors of a smartphone / tablet. For example, when you receive a call and you bring the device to your ear, the display does not lock and you accidentally press the call reset button. Or the opposite situation, when after a conversation the screen does not want to light up. This particular issue is caused by a malfunctioning proximity sensor.

In this article, we will show users how to calibrate any sensor on the device and get it to work normally.

In order not to deviate from the above, first of all, we will consider setting up the proximity sensor. All manipulations will be performed on a device running Android 5.0.2, so there may be slight differences in instructions for different versions.

Proximity and Light Sensor Calibration

Method one

The first step is to get into the engineering menu of your device. For this we use a special program, for example, "Launching the MTK Engineering Menu", which you can download at the specified

1. Download, install and launch the application.

2. After starting, switch to the tab called "Hardware Testing"
3. Scroll to the bottom of the list and find the "Sensor" item here.
4. In the next window, select the item called "Light / Proximity Sensor".
5. Click on PS Calibration and select Calibration.
By moving your hand over the sensor, you can see how the PS value changes from small to large values. When the hand approaches, it should increase and vice versa. In addition, this value should change depending on the incidence of light on the sensor. If this happens, the sensor does not need to be calibrated.

If it does not react in any way, then we put the smartphone on a horizontal surface and press the Do calibration button. After that, the message Calibration success will appear. The sensor should now work stably. If this did not happen, go to the next method.

Method two

We will be using the third party Proximity Sensor: Reset, which you can download

Download, install and run "Proximity Sensor: Reset".

Click on the huge "Calibrate Sensor" button.

We close our sensor with our hand and press the Next button.

Then we remove our hand from the sensor and press Next again.

After that, press the red "Calibrate" button and confirm the action by pressing the "Confirm" button.

Then a request will appear to grant root rights to this program. We allow and after a few seconds the device will reboot.

That's all. If, after all these manipulations, the proximity sensor continues to "dull", then there is only one option: take the smartphone to a service center, because we cannot do anything else ourselves.

Calibration of the touchscreen

Many users often face the following problem: when you tap the screen, it either does not respond, or perceives the touch "in the wrong place". To deal with this problem, you need to calibrate the screen.

Method one

We will use a third party Touchscreen Calibration software that you can download

1. Download, install and run the above application.

2. Press the blue "Calibrate" button.

3. The program will ask you to make one "tap" on the screen.

4. After a single press, you will need to make a double tap.

5. Then we are required to make a long press.

6. The next step is to slide your finger to the right across the display.

7. Then we put two fingers on the screen and move them to each other, as if we want to reduce the image or text.

8. Then we do the opposite, as if we want to enlarge the image.

9. The message Calibrate Successful will appear on the screen, which means everything went well.

Method two

We use another popular Display Calibration program, which can be found at the specified

Download, install and run Display Calibration.

Click the big blue "Calibrate" button.

Upon completion of the process, a "Calibrate Successful" message will appear confirming successful completion of the calibration.

On the Internet, you can find many similar programs that work on the same principle, so you should not have any problems related to their development.

Calibrating the accelerometer (Gsensor)

We need an accelerometer to perform a number of important functions: it is responsible for the orientation of the device in space, is used by many applications, etc. This allows us (gamers) to enjoy those games that use this feature. Most often it is, of course, racing. And if Gsensor is "dumb", then it will certainly upset us. However, let's leave this lyrical digression aside and get down to business.

Method one

In this case, we will use the engineering menu of the android device.

1. We go to the engineering menu of the smartphone / tablet using the above program.

2. Go to the "Hardware Testing" tab.
3. At the very bottom we find the "Sensor" item and click on it.
4. Select "Sensor calibration".
5. Next, click the "Calibrate Gsensor" button.

6. The device must lie on a level, horizontal surface. The current data should be equal to zero (I have irregularities on the back cover, so the readings in the screenshot are a little inaccurate). Press the "Calibrate (40% accuracy)" button and after a couple of seconds we will see the "Operation Succeed" message.

That's all, we exit the engineering menu. The accelerometer is now calibrated.

Method two

We will now calibrate using a third-party software called Accelerometer Calibration Free, the free full version of which you will find

Download, install and run this application.

On the screen we will see a large crosshair with a green center, as well as a red ball. We turn our smartphone / tablet so that the ball rolls into the green zone, and then press the "Calibrate" button (the whole minigame turned out).

We are waiting for the completion of the process.

Voila, you're done. Note that the advantage of this program is the automatic calibration of the accelerometer. It is very convenient. In the future, you will not have to monitor the work of Gsensora, at the slightest inaccuracies the application will calibrate it itself.

Method three

There is another good application called Spirit Level, which, in addition to calibration, performs a number of additional useful functions. You can download the application

1. Download, install and run Spirit Level.

2. Press the "CAL" button.

3. In the menu that appears, press the same button again in all five items.
4. A message like this will appear.

That's it, the device has been calibrated. Note that this program has three different skins, which visually makes it very interesting.

Calibration of the magnetometer

This sensor is required to determine the earth's magnetic fields. Without it, no built-in or user-installed compass will work. This function will be useful for hunters, travelers, tourists, etc.

Method one

To calibrate the magnetometer, we will use the wonderful Compass application from the developer MacroPinch. Besides calibration, which is just an optional feature, this app is a complete compass. The program can be downloaded

Download, install and launch the Compass application.

Press the "menu" button in the upper right corner of the screen.

In the list that appears, set the "calibration" slider to the active position.

All. The magnetometer will now work perfectly.

Outcome

1. Go to the application.

2. Press the "Quick TuneUp" button.

That's all. In a few minutes the program will "polish" almost all the sensors of the device and even calibrate the battery.

If you have any problems or questions during the sensor calibration process, describe them in the comments to the article, and we will definitely help you!

To some people, "calibration" seems like a very scary and incomprehensible word. They don't even know that professional photographers are necessarily calibrating a new monitor. As well as sometimes it is required to calibrate the screen of a smartphone. But not in the same sense - no one will give you detailed adjustments to the color scheme. In this case, the sensor is calibrated. It allows you to ensure that the device will perfectly recognize different types of clicks. In short, today we will talk about how to calibrate the sensor on Android.

Perhaps we have intimidated you a little. If you thought that calibration is required for absolutely any smartphone and tablet, then this is not the case. Modern technologies have allowed the creators of such devices to achieve the ideal behavior of the touchscreen and accelerometer. In this regard, calibration is often not needed on new devices - they already function perfectly.

But on older gadgets, the Android operating system may behave incorrectly. Especially if the device has a resistive shield. Fortunately, even in the olden days there were not many smartphones with this type of touchscreen display. And now even ultra-budget devices receive a capacitive screen, which does not require special adjustment.

It should be noted that some devices require sensitivity adjustment. If you calibrate the screen on Android, you can reduce or increase the sensitivity. This way you can fine-tune the behavior of the device to your expectations. This is especially true when buying a new device when you can't get used to its behavior.

Note: both a smartphone and a tablet can be calibrated. The type of device is not at all important, you just need the Android operating system.

Returning to new devices, they may also need calibration, but only in the following cases:

The gadget was repaired after getting into the water;
The device was replaced by a screen;
The smartphone was seriously hit when dropped, although it did not receive any visible damage.

Why can't you calibrate the color reproduction?

In the introduction, we talked about professional photographers who calibrate the monitor to display colors as close to reality as possible. Why can't this be done on a smartphone or tablet?

Everything is very simple. To calibrate monitors, special devices are used that are not designed for use in tandem with a portable gadget. And smartphones and tablets do not support color calibration at the hardware level - you will not find the corresponding settings either in the Recovery menu or anywhere else. Easy color adjustment is available only to owners of Samsung smartphones equipped with a display created using technology Super AMOLED... And it consists only in choosing one of three or four picture display modes. If you want to see the available options, then perform the following manipulations:

Step 1. Go to " Settings».

Step 2. Go to the section titled " Display».

Step 3. Click on the item " Screen mode».

Step 4. Choose the mode that suits you. The brilliance of the picture displayed on the screen will depend on it.

Sensor calibration

As for the sensor, it is easiest to calibrate it on devices with a resistive screen. A special utility is installed on them, launched from " Settings". It allows you to quickly calibrate the sensor so that exactly the icon or button to which you put your finger is pressed. Find a similar item " Settings»It is possible even on old MP3-players equipped with a rather large display (it is pointless to calibrate the sensor of a small screen).

But what about modern smartphones that have a capacitive touchscreen? Is it really impossible to calibrate them? Fortunately, in some cases this is still possible. Moreover, sometimes you can even slightly adjust the color reproduction, and not just the sensor. But in fact, it all depends on the specific model of the device. It is possible that the manufacturer of your device has closed access to certain parts of the operating system, in connection with which you can download the program for calibration, but it will not work properly.

To calibrate the touchscreen, we recommend downloading the application, which is called: Touchscreen Calibration ... It is free and has a simplified interface. To calibrate, follow these steps:

Step 1. Run Touchscreen Calibration.

Step 2. Click on the blue button that prompts you to start calibration.

Step 4. At the end of the procedure, you need to click on the " OK»In the pop-up window.

Step 5. Reboot your device.

If you need to check the operation of multitouch, then we suggest you download the following applications:

Tooch Multitest - has a simplified appearance, but easily diagnoses multitouch operation. If the sensor does not work in some area of \u200b\u200bthe screen, then you will certainly notice it.
MultiTouch Visualizer 2 - This program shows how many touches the screen has detected. It makes this application with the help of large multi-colored rings, each of which is signed with a corresponding number. Additionally, the utility tests the pinch function.
MultiTouch Tester is another simple application that fixes the points of contact of the screen with your fingers. Problems with touch detection on one axis are possible!

Using Display Calibration

If the display seems too dim for you, or you notice uneven distribution of pixels, then use Display Calibration ... If earlier we considered a program for calibrating the Android touchscreen, then Display Calibration adjusts the color rendering. And in some cases, it manages to slightly improve the display of the picture.

Step 1. Run the application.

Step 2. Click on the big button " Calibrate».

Step 3. Wait for the end of the calibration process.

Step 4. After the pop-up window appears, click on the " Close»And restart the device.

Summarizing

In today's article, we tried to talk about all the known methods of calibrating the smartphone screen. Unfortunately, most often they are either inaccessible to the average user, or make subtle changes. But it just so happens that you cannot get a display created using Super AMOLED technology from a TFT screen - any LCD panel displays a strictly defined color range. As well as the sensor, most often it is not able to offer greater sensitivity than the one for which it is sharpened.

Notice a drop in screen sensitivity and responsiveness? Are there non-working areas or areas requiring increased effort? Do not rush to get upset, run to a repair shop or for a new Android smartphone. Maybe the touchscreen needs calibration.

What is calibration

Calibration refers to a set of measures aimed at setting up the display in order to restore performance and troubleshoot.

When and why calibration is needed

The registration of commands by the user is monitored by built-in sensors. A malfunction or faulty settings lead to unpredictable consequences, up to a complete failure of the touchscreen. Falls, shocks, moisture ingress, electrostatic discharge, or improper factory settings can contribute to this. Often, loss of sensitivity or inactive areas appear after gluing glass, film or changing the screen module. Therefore, calibration, in most cases, helps to fully or partially correct the incorrect operation of the sensors.

Calibration Preparation and Troubleshooting

Use a dry cloth to clean dust, moisture and greasy fingerprints from the screen.
It is required to remove the protective film / glass, since the dust caught under the edges, the screen perceives for pressing by the user. Glass or film often degrades sensitivity.
Remove covers, jewelry, and accessories. The metals, alloys and magnets used often have a negative effect on the sensors.

After each step, check if the problem is gone. If not, proceed with calibration.

Calibration methods

The procedure is free of charge and does not require additional equipment. It is performed using the engineering menu and / or applications.

Calibration through the engineering menu

A hidden section with settings is used to edit the operation of sensors. To enter, you need to enter a combination of numbers and symbols in the window with the dialing of the phone number, in the format: * # * # хххххх # * # * or * # хххххх # * or * # * # хххххх * # *, where хххххх is a set of numbers. The combination and numerical code is different for each manufacturer. Therefore, you need to set a search query on the Internet. For owners of devices with SoC MediaTek, MTK Engineering Mode Start application is available, which launches the engineering menu without the need to enter a code.

Important! The changes made in the engineering menu are saved even after a reboot. Therefore, you should not change other settings without proper knowledge and preparation.

After going to the engineering menu, you need to perform several simple steps:

At the top of the screen, select the "Hardware Testing" section.
Scroll down the list and select the "Sensor" item.
Among the suggested options, click "Sensor Calibration" and then "Gsensor Calibration".
Next, you need to clear the calibration values \u200b\u200bby pressing the "Clear Calibration" button.
Then carry out the calibration by pressing "Do calibration 20% tolerance" or "Do calibration 40% tolerance". After that, the sensor calibration is considered complete. It is recommended to start with a lower value, otherwise try the second option.

Calibration by application

This method is suitable in case you failed to enter the engineering menu or the calibration did not give the desired result. Then you need to download one or more calibration applications.

Touchscreen Repair

The program divides the working area into 4 sections, determines the response time and builds one value. It also reduces response time.

TouchScreenTune

The utility adjusts the screen sensitivity, and also allows you to ignore the touch of the palm. This is useful when drawing or entering information with a stylus. Requires superuser rights to work.

SGS Touchscreen Booster

The app changes the sensitivity values, registration time and minimum touch. The maximum multitouch value is also configured. There is a shortcut to enable / disable settings.

Touchscreen Calibration

Calibration requires six simple steps: single and double tap, long press, etc. At the end of the test, the program will assess the accuracy of the work and make the appropriate changes.

Output

Self-calibration saves time and money, saves you the trouble of going to the repair shop and postpones the purchase of a new device. And the simplicity of both methods does not require significant knowledge or experience. If the calibration did not give the desired effect, and the problem persists, then you will have to carry out additional diagnostics or contact specialists.

Although touch-sensitive devices are very convenient, over time, sensor performance can lose accuracy, and this, in many cases, does not depend on the type of screen or the make and model of the device.

In this regard, any such sensor (and screen) sooner or later needs debugging or calibration. This article describes how to calibrate and configure the screen on Android.

The essence of the problem

It is known that while the phone or tablet is new, the quality of the sensor is very high.

It reacts quickly enough to touches, quite accurately determines the point on which the user pressed, etc.

But over time, as the actual life of the device increases, it decreases significantly, and errors and inaccuracies begin to occur.

So how do you know when you need to calibrate the display on your mobile device?

Usually, you have to do this when they start errors of the following type appear, which significantly interfere with work:

The sensor does not always work - some actions are not recognized and the device does not react in any way;
Some types of actions are not recognized or work poorly, but not all (for example, tap can work fine, while swiping does not work every time, or vice versa);
The actual place where the action was performed is not accurately determined (for example, not the button you actually touched is pressed);
The waiting time for a response after performing an action has significantly increased on the touch screen;
The display became worse only when using the stylus, or, on the contrary, only;
In graphic applications, this problem can manifest itself as line break etc.

The occurrence of such a problem, in fact, is a normal and natural process, the consequences of which can be easily eliminated by basic means, that is, without involving a service.

When does it arise?

Long-term use of the device - the first reason that the quality of the sensor on a phone or tablet will gradually decrease.

This is a normal process that all modern phones are subject to, the more the lower quality screen is installed on the device.

Also, such a phenomenon also occurs, on the contrary, with too long inactivity of a device that was previously actively used.

In some cases, such screen debugging is required immediately after purchase, since it happens that initially the sensor is configured incorrectly.

After changing the display, it is also almost always necessary.

Changes in software settings also affect the quality and speed of the sensor. It can be any, and there can be settings, deliberately or accidentally, changed by the user. For example, the sensitivity of the sensor can be changed for convenience in the phone settings.

But, a decrease in the quality of the device can occur for other reasons.

For example, this happens when scratches and scuffs appear on the screen, a poor-quality protective film is applied, or when bubbles remain under it, etc.

In this case, the calibration will not be effective enough and the problem will not be eliminated.

Definition

What is calibration, and how does it solve the problem of an unresponsive or inaccurate sensor?

Calibration is the adjustment of the touch screen performed by the device based on the user's actions on the sensor.

The standard calibration procedure is as follows: Dots, circles or crosses appear on the screen in random order and the user must click on them.

Based on this process, the system builds a certain scheme of points and areas on the screen, thus determining which of them are more responsive, which are less, which are more accurate, and which are lower.

Based on the data of such diagnostics, the system makes adjustments and troubleshooting.

Calibrate exactly with the device you use it most often. If you use the stylus more often, then calibrate the screen with it, but if you usually use the phone manually, then use your finger to calibrate. This is due to the fact that different objects have different thermal conductivity and the display may react to them slightly differently from a technical point of view.

Calibration methods

Debugging can be done in several ways. The simplest and most effective ones are described below.

If, after applying one or another method, there have been no significant changes for the better, then it is advisable to try another method.

Device settings

Since device calibration is a necessary process, the creators of the majority have incorporated such a function into the device settings. How do you use it?

1 Go to Device settings;

2 Go to the section Screen or Display (may be called differently, depending on the device model, version of Android or the nature of Russification;

3 Go to the section Screen Calibration/ calibrate the screen or the like (note that there is no such section at all on some devices, this means that debugging will have to be performed in a different way);

4 If there is such a function, then after clicking on it, a special test will be launched, in which you need to click on certain points as they appear or in a specific order (on different devices, the order of the test may change slightly, but the essence remains the same);

5 After completing all the necessary steps, the system will show you a notification that the test is over, now section Settings can be closed.

Sometimes, significant improvements in sensor performance are seen right after that. But in most cases, the tablet or smartphone needs to be rebooted.

Engineering menu

Engineering menu - this is a special section of settings, where you can carry out more complex and more accurate debugging and tuning. In any case, there is a calibration function in it, for example, on those devices for which this test is not included in the simple device settings menu.

Download and Install Touchscreen Calibration

In order for this application to appear on your phone, do the following:

Open the Play Market app on your device;

In the search engine, enter Touchscreen Calibration and open the application with a phone icon and a wrench;
Click the Install button;

After that, it will automatically download and install, a shortcut will be created on your device's desktop.

After clicking on the Install button, the application will automatically download and install on your device. You can find a shortcut to launch it on the main Desktop.

The application is distributed, focused on the English-speaking user, therefore it does not have Russification, just like the previous one.

It has a fairly wide functionality and helps to carry out high-quality settings. In order to debug the sensor using it, do the following:

1 Start the application from the shortcut to Desktop;

2 Find the item in the main menu of the program Display Calibration and click on it;

3 Now you have to wait a bit, since this process is presented not in the form of a point-by-point test, but in the form of automatic troubleshooting, and then - automatic screen debugging;

4 When starting the process, a notification will appear on the app home screen showing the progress of debugging;
