Where is the screen calibration in the settings? Display calibration in Android: when is it needed and how to do it? Via the Quick TuneUp app

Owners of mobile devices running on the Android operating system often encounter the problem of the touchscreen not responding correctly to touch. Calibrating the Android screen usually helps resolve such problems. Without periodic implementation of this procedure, the smartphone begins to respond to entered commands with a significant delay and confuses the touch buttons.

Problems with display operation in most cases do not arise as an independent phenomenon, but are associated with some extraneous influence on the smartphone. There are several reasons that can cause a failure in the screen settings:

If the device begins to “glitch” after such situations, touching certain points on the touchscreen triggers incorrect commands, and the screen becomes insufficiently sensitive, it is worth conducting a test to check its reaction. This procedure is performed in the following order:

The protective film is removed from the display, which is necessary to ensure maximum contact with its surface.
Any group of characters is entered on the keyboard.
Check the correspondence of the pressed buttons with the entered data.

Identification of any discrepancies serves as a signal that it is time to calibrate the gadget. This can be done both in service centers and independently.

There are few calibration methods, but there are enough of them to carry out this procedure quickly and without much difficulty. To normalize the operation of a damaged touch sensor, you can:

It is worth noting that in most Android devices from manufacturers Lenovo, Nokia, Samsung and others, this process will be practically no different. The only thing is that most often owners of gadgets with resistive screens have to face problems, for example, Lenovo A319 (Android version 442 Kit-Kat), Samsung SM - J 200 Galaxy J2 (android v 5.1 lollipop), HTC Desire 601 Dual Sim (v 422 Jelly Bean), etc.

TFT display technology is practically not used today, and is found only in budget and outdated models. Devices with capacitive screens are considered to be of higher quality and more reliable.

Using Settings

To calibrate the screen on Android without using third-party programs, you will need to follow a certain algorithm of actions. This method is considered the fastest, but often it turns out to be ineffective. To improve sensor performance you need to:

Turn on the gadget and wait for the OS to fully load.
Quit all games and other active applications.
Open “Settings”, where click on the “Display” sub-item.
From the proposed list of operations, select “G-sensor calibration”.
Place the device on a flat surface, which is necessary for its correct setup, and press the “Calibrate” button.
Follow the instructions on the display.
After a short break, reboot the device and check its functions.

This setup can be done on any smartphone with a touch screen. But it is important to remember that this method does not always achieve the desired result. For example, if it is not possible to place the phone on a flat surface, the sensor may occasionally malfunction.

Engineering menu

To calibrate the Android touchscreen after replacing the display or simply if the need arises, you can also use a special menu. It allows you to produce many tinctures that are not available in normal mode. To use the engineering menu on the keyboard intended for dialing numbers, enter the code *#15963#*, *#*#6484#*#* or *#*#4636#*#*. In the window that appears, you must perform the following actions:

Open the Hardware Testing item.
Press the Sensor button.
Go to the Calibration section.
Select Clear Calibration.
Click Do Calibration.
Exit the menu by pressing the back button several times.

Existing Applications

Users with access to Google Play Services can calibrate the touch screen using special applications. The Play Market contains a wide range of free programs that are very easy to install and convenient to use. Moreover, almost each of them allows you to get good results. The most popular applications are Power Bubble, TouchScreen Calibration, Clinometr and many others.

Power Bubble

Power Bubble has a user-friendly interface and several special features. The main advantages include:

To work with the application, it is enough to select the desired screen orientation or set the automatic mode upon initial launch. After this, they begin setting up the wheelbarrow, for which they place the gadget on a flat surface and press the calibration button. The word Calibration and Wait should appear on the screen. Next, a zero degree value will be formed, which will indicate that the program is ready to function.

Clinometr and others

A very high-quality screen customization application is tscalibration. It is equipped with a large number of options that allow for the most accurate calibration. To use a pre-installed program, you need to launch it from the smartphone menu and press the Calibrate button. Then you will need to perform a series of simple steps, after which a message indicating that the setup was successful will appear on the display.

Clinometr is another good tool that is designed to improve the sensitivity of touchscreen feedback. The application is used not only to solve simple problems, but also in more complex areas to accurately measure the angle of inclination of the gadget. It has a number of advantages.

What is calibration

Calibration includes a set of measures aimed at adjusting the display in order to restore functionality and troubleshoot problems.

When and why is calibration necessary?

The registration of commands by the user is monitored by built-in sensors. A malfunction or incorrect settings lead to unpredictable consequences, including complete failure of the touchscreen. This can be caused by falls, impacts, moisture, electrostatic discharge, or incorrect factory settings. Often, loss of sensitivity or inactive areas appear after sticking glass, film or changing the screen module. Therefore, calibration, in most cases, helps to completely or partially correct the incorrect operation of the sensors.

Preparing for calibration and troubleshooting

Use a dry cloth to remove any dust, moisture, or greasy fingerprints from the screen.
It is necessary to remove the protective film/glass, since dust trapped under the edges is perceived by the screen as being pressed by the user. Often glass or film impairs sensitivity.
Remove covers, decorations and accessories. The metals, alloys and magnets used often have a negative effect on the sensors.

After each item, check if the problem has gone away. If not, proceed with calibration.

Calibration Methods

The procedure is free and does not require additional equipment. Performed using the engineering menu and/or applications.

Calibration via the engineering menu

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

Important! 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 “Sensor”.
Among the suggested options, click “Sensor Calibration” and then “Gsensor Calibration”.
Next, you need to clear the calibration values by pressing the “Clear Calibration” button.
Then perform calibration by pressing the “Do calibration 20% tolerance” or “Do calibration 40% tolerance” button. After this, sensor calibration is considered complete. It is recommended to start with a lower value, otherwise try the second option.

App calibration

This method is suitable if you were unable to enter the engineering menu or if the calibration did not give the desired result. Then you will need to download one or more calibration applications.

Touchscreen Repair

The program divides the work 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 your palm. This is useful when drawing or entering information with a stylus. Superuser rights are required to operate.

SGS Touchscreen Booster

The application changes the sensitivity values, registration time and minimum touch. The maximum multi-touch value is also adjusted. There is a shortcut to enable/disable settings.

Touchscreen Calibration

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

Conclusion

Self-calibration will save time and money, save you from going to a repair shop and postpone 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 a specialist.

Sometimes strange things can happen to the screen of a phone or tablet - it seems to stop obeying the user’s fingers, that is, clicks do not occur or occur, but, for example, when you click on the letters Y, the letter E appears on the screen. Is the screen really over? It is unlikely, most likely this is due to the incorrect operation of the touchscreen. In most cases, the problem can be easily resolved by calibrating the screen.

What is screen calibration on a smartphone or tablet?

Screen calibration, often called sensor calibration, is a type of display adjustment that optimizes the operation of the touchscreen and improves the response of the sensor when pressing the screen with your fingers (in some cases, if any).

As a rule, the device does not require screen calibration after purchase, although there are also cases where the sensor “does not listen” to the user. Over time, changes may occur and then you will have to use screen calibration.

How can you tell if the sensor is working correctly? If it works properly, you will not experience any problems while using the device. For example, if you are typing a message and all the letters you clicked are displayed on the screen, you do not need to do anything. It’s another matter when you click on one letter several times and only after that it appears on the screen or does not appear at all, or a completely different letter appears instead - all this may indicate that the sensor clearly has problems. However, we should not forget that the problem may be hidden not in the touchscreen, but, for example, in the film glued to the screen. In some cases, these may be traces left by something sticky. Wipe the screen with a napkin and see how the sensor works. If so, then it needs to be calibrated.

How to calibrate a sensor without third-party software?

There are two ways to calibrate the sensor - using internal Android software and using third-party software (applications). In the first case, the built-in software in your operating system is used. But be careful, not all firmwares have a third-party calibration tool!

And now - simple instructions.

Go to your device settings.

Find the Phone Settings or Tablet Settings section.

Here find the “Calibration” item. It may be located in another section, for example, in the “Screen” section.

Click on the "Calibration" item.

Perform the necessary manipulations. This could be, for example, pressing certain buttons on the screen or simply tapping the screen.

In our case, there is no built-in software for calibrating the screen, so we are forced to use an application from the Google Play Market. If this is your case, then read the instructions below.

How to calibrate a sensor using third-party software?

We go to Google Play Market and write display calibration in the search.

Select the application and click “Install”.

The application is installed. Let's launch it. The good thing about this particular application is that you practically don’t have to do anything - just click on the big blue Calibrate button in the center of the screen.

The calibration process has begun. Do not touch anything or turn off the device!

After about 30 seconds (numbers may vary), you will see that the calibration is complete, as indicated by the date of the last calibration.

Check the functionality of the touchscreen.

What to do if calibration did not help?

Try other apps from the Market. If they don’t help, you can try to restore the device to its original form. You can also try to reflash the device. If this does not help, most likely the touchscreen has died and requires replacement. Contact the service center.

After touchscreen smartphones replaced push-button phones from the gadget market, users were faced with a new problem. The sensor can " be dumb”, do not respond to requests, or even during a touch, open something that is not what the user needed, as if displacing him. In order to avoid such problems, the sensor must be calibrated.

Before you calibrate the sensor on Android, you must be sure of the accuracy of your actions. First, you have to check your smartphone for touch errors. Turn on, for example, a message and press certain letters. If what you clicked appears on the screen, then no calibration is required. Well, if the symbols are different, then you need to configure your smartphone.

It is necessary to calibrate the sensor:

Every month or two of using the smartphone (if you notice obvious changes in the behavior of the display)
Gluing the glass to the display
Having bought a smartphone second-hand or a new one
After the fall, flooded with water
After changing the touchscreen and screen
After changing the protective film

How to manually calibrate the sensor on Android

It’s worth saying right away that a large number of gadgets can be configured completely differently, and perhaps you are the owner of such a smartphone. The manufacturer may change or even eliminate this setting in the smartphone. Below we will consider the option of setting up calibration in the usual way.

Go to settings, and there go to the “Phone Settings” tab.
Go to the “Phone calibration” tab.
After this, a cross with a target will appear on a white background in the middle of the screen. Click on it three times.
After this, the calibration will be completed. After this, check the sensor in the same way as described above.

Using apps

If your smartphone does not have the ability to configure screen calibration, you can use a special application. In this case, it will be identical as in the standard version, and you will need to do the same as in a smartphone with this built-in feature. Some similar applications give possibility of setting more precisely than "relatives".

To search for such applications, go to Google Play through the application, and enter “Screen calibration” in the search, and then select the one you need. Unfortunately, we cannot advise you on specific programs, since they will display differently on different devices. BUT, I personally recommend the applications I used!

An Android device can be configured in a variety of ways, and in particular, many utilities have been created to help with such a simple task. “MachScreen Calibration” is probably the most popular program in this case. Also, “Touchscreen Calibration” is an equally popular and simple option for sensor calibration.

Android screen calibration through the engineering menu

The most reliable and sure way to configure the correct operation of your screen!

Go to "Challenges"
Enter a special code (it may differ on different models, try it)
*#*#3646633#*#* , *#*#4636#*#* ,*#15963#* or *#*#6484#*#*
Next we find an item with screen calibration (different variations on different versions of Android, something with “Sensor”
After going to the calibration submenu, press start
If everything was done correctly, you will see the calibration result

Now in pictures. An example of entering the engineering menu is given at Xiaomi Mi5.

This code worked on my phone. We are looking for a calibration item, in my case it is number 9. Clicks “Calibrate”

If none of the above access codes to the engineering menu are suitable, then watch the video instructions, it will definitely point you in the right direction!

Failures in the operation of the Android smartphone's sensor are a common problem for not the most careful users. It is enough to drop your phone once, spill something on it, or sit down without noticing it, and there is a significant risk of damaging the touchscreen. If it is damaged, you will no longer be able to use the screen normally; typing a message or simply answering a call will no longer be possible. This smartphone is absolutely useless. That is why it is necessary to calibrate the screen to correct all problems. However, it's not that simple.

To begin with, you should make sure as much as possible about the sensitivity of the sensor. To do this, remove the protective film, if any, and try to type a letter.

If touch recognition occurs incorrectly, for example, instead of one letter a completely different one is typed, then screen calibration is simply inevitable. This can be done in different ways, depending on the phone model, brand, and version of the Android operating system.

Today we will look at various calibration methods on different devices; you can try everything, depending on the situation.

How can I do this through the settings of the device itself?

Due to the fact that problems with calibration are a common problem for users, Android OS developers have added the ability to do it without installing unnecessary applications.

In order to go directly to the settings, you need to open general “Settings”, go to the “Display” section, and there we find an item called "Screen calibration". If there is no such item, then find a similar one; the name may differ on different devices and versions of the Android OS.

The calibration process itself is a small test where you need to touch the screen in different places. Once completed, the device will automatically remember the touches, after which the calibration can be considered complete.

Important. Upon completion of all actions, you should make sure that the touchscreen is accurate; depending on the result, calibration can be done again.

We carry out the procedure through the engineering menu

If you don’t know much about smartphones, this is probably the first time you’ve heard about this setup mode.

The engineering menu is a whole storehouse of a wide variety of configurations for your Android. Once in it, you can access all available configurations. This mode is suitable for users who like to fully customize this or that device for themselves.

So, what do you need to get into this very menu? First you need to open the dialing window and enter the following combinations there:

* # * # 3656633 # * # *
* # 15963 # *
* # * # 4636 * # *

Which combination is suitable depends on the smartphone itself.

If suddenly nothing works out, then in order not to suffer with input, you can simply download a special application from, it’s called MTK Engineering Mode Start. You can use it to perform various manipulations with your phone.

Closer to the point. Here we are in the engineering menu. Now you need to do the following:

Using apps

There are many programs that are designed specifically for sensor calibration. There are both paid and free versions. Some of them require Root rights on the device. Below we will tell you about several such applications.

To use this program you need root rights, so before proceeding with the settings, we should take care of this. We have already described how to get root rights on the pages of our website; information about this is freely available.

Primarily created for tablets. The procedure is carried out through the same test, but in addition can significantly improve not only the accuracy of touch recognition, but also improve overall performance and efficiency. This program is indispensable for some Android tablets with handwriting or drawing functions.

The interface is designed in such a way that you can figure it out intuitively, there are no complex settings, and the most ordinary user can figure it out.

It is capable of not only calibrating the touchscreen, but also measuring the tilt angle, tilt height, and the tilt of an object relative to gravity.
