Calibrating the Android screen, or rather the sensor, is a typical task, it can be done through the engineering menu. Actions that relate to the wording - android screen calibration include setting up a touch-type display in order to appropriately execute commands by the device by touching the sensor with a stylus or fingers. Without such a setting, the device will work, but there will be a number of undesirable consequences during the operation of the gadget.
Individual owners of devices on the Android operating system that are equipped with touch screens may sometimes encounter the undesirable problem of screen “disobedience”. In other words, when touching with a stylus or a finger at a certain point on the touchscreen, the gadget perceives it as a completely different command.
Or there are situations when the sensor executes commands only after the third or fourth attempt. As a rule, the cause of these problems is the incorrect operation of the screen itself, for which it is necessary to calibrate the touchscreen of the device.
Urgent and correct calibration of the touchscreen on Android may be required in almost all cases, if the smartphone fell from any height, and after the device accidentally enters the aquatic environment, this procedure is mandatory.
Also, sensor calibration on android will be required after repair work on replacing the screen, the appearance of a water spot under the glass of the screen, and after suffering other, at first glance, minor damage.
To check the need for this procedure, you must perform the following steps:
- Remove the special film protecting the screen (to ensure the most correct operation of the sensor);
- Enter any letter or number;
- If there is a discrepancy between the button pressed on the gadget screen and the information entered, setting the touchscreen is necessary.
Basic Calibration Methods
Two methods are used to bring the sensor-sensor knocked down from its normal position into conformity.
These main methods include:
- Using special programs for the android system;
- Self-correction.
It should be noted that for many brands (Samsung, HTC, Nokia and other Android devices), the calibration steps are practically the same and identical.
Android device manufacturers typically use two types of sensor:
- Resistive (all sorts of problems very often arise with a screen made using this technology, so the setting is more in demand here, but such screens are practically not used today - these systems can only be seen in budget or outdated models);
- Capacitive (used in most gadgets, is more reliable and of high quality).
Touchscreen calibration using android
In the absence of access to the assortment Google Play the display of an android device can be configured in another way without any problems.
The step-by-step instruction in this case may look like this:
- Go to the gadget in the "Settings" menu;
- Select the item “Phone settings;
- Find the inscription “Calibration, press the button;
- A cross-target will appear on the screen, which has a dot inside;
- Click on the center of the appeared target at least three times.
After the actions taken, the device will automatically memorize the touches. Thus, the calibration will be considered completed. After completing the setup procedure, it is necessary to check the operation of the touchscreen by the result of pressing a certain character on the screen, which should appear after its introduction.
Android screen calibration apps
You can adjust the sensor using a special software. In free and free access on the Internet there is the necessary software in order to successfully carry out this process.
The software is fairly easy to install and operate. But the most important thing is that practically from the use of any of them you can get a positive and effective result. In the Google Play Store, you can find free apps like Bubble and many more.
Application
The most popular screen calibration app for Android. Just a few taps on the smartphone screen and the screen is calibrated - you only need to restart your phone and enjoy the precise operation of the device's touchpad.
Application
This program has an excellent interface, also has some additional special features. Application advantages:
- Bubble is free software;
- Works great with tablets and smartphones;
- Advertising is disabled in the settings, or it can be left to encourage developers;
- Excellent graphics;
- The presence in the application of a special display that displays the angle of inclination with the highest accuracy in fractions of a degree;
- Ease of use;
- The ability to fix the angle with a gesture or a click;
- The presence of a sound signal at the zero position of the angle;
- If necessary, the ability to lock the screen orientation (horizontal or vertical);
- Ability to reinstall the application on the SD card;
- Disabling, if necessary, the "sleep" mode during the operation of the program;
- Using full screen mode.
Using the program is completely easy. To do this, after the initial start, in the settings, select the type of device screen orientation (or set the “Auto” mode) and calibrate by level.
For this purpose, the phone is installed horizontally and the calibration button located on the left of the screen is pressed for a short time. On the touchscreen should appear - "Calidbration", and then - "Wait". The application will be ready for operation when the zero degree value is viewed on the screen.
The application is a program that allows you to adjust the screen settings of a touch device, while increasing its sensitivity and efficiency. Advantages:
- When using a protective film on the touchscreen, this application can significantly improve the sensitivity of the sensor;
- The slowing down effect from the use of a protective film is eliminated;
- When using such a device as a stylus, a kind of gadget tuning becomes simply necessary with the help of this program. Using this application, you can enable complete ignoring even a touch from the palm of your hand (after setting, the hand can rest on the screen when using the stylus);
- If you need to use different settings, you can create separate shortcuts for quick launch of the application;
- The application has a free version.
The program is a professional tool for fine-tuning the level in the iPhone or iPod Touch. The application is used for solving common tasks or in more complex applications where the tilt of the device needs to be measured quite accurately. Advantages:
- The possibility of full-screen mode, which allows you to switch by clicking on the lower and upper arrows located in the middle of the gadget screen;
- Advanced two-way calibration, allowing adjustments to be made on surfaces that are far from flat. Any direction is calibrated separately in order to obtain the required accuracy;
- Possibility of free download;

Possible Calibration Issues
In the event that, nevertheless, the device is not calibrated in the way chosen for this purpose, or the application used does not give the necessary positive changes, then experts recommend trying another program, since there are quite a lot of them, the software in this direction is very diverse. You can also try "Hard reboot" or in other words reboot the device.
The last option for calibration can be considered contacting service center. A similar problem with the screen of the device may be not only in incorrect settings, but also in more serious reasons. In particular, in the hardware failure of the device elements or the presence of a factory defect. In this case, it is better to contact a specialist to fix the problem.
It should also be noted that, together with screen calibration, the gadget may need to check and adjust the screen sensitivity parameters for its subsequent high-quality work.
Checking and adjusting sensitivity settings
The sensitivity of the sensor is adjusted according to the activity that is supposed to be on the gadget.
To do this, in the device applications, select:
- Options;
- Special abilities;
- Screen sensitivity;
- Choose from the options provided.
Important: You can test the screen setting without gloves or in them, depending on the planned operation of the gadget.
Every year, dozens of new smartphone models are released by manufacturers. Some as a distinguishing feature can boast of their low cost, others high performance, others ergonomic design, the fourth endowed with excellent energy-saving characteristics, a powerful battery and shock resistance. But none of these devices can be 100% protected from breakdowns of a different nature. One of these troubles is the spontaneous operation of the touchscreen, which, as a rule, is inherent in Chinese budget smartphones. In view of what the sensor on the phone is pressed by itself and how to deal with this problem, you will learn from the article.
Incorrect operation of the touchscreen is not the most pleasant phenomenon, but the problem is fixableWhat are the reasons for the spontaneous operation of the touchscreen
Conventionally, the reasons that the sensor itself is pressed can be divided into two categories:
- Software failure - occurs due to errors in the software (software) of the smartphone;
- Hardware failure - errors associated with damage to the component parts of the device.
Depending on the model of your smartphone and the circumstances under which the erroneous operation of the screen occurred, it is more or less likely to say which of the above failures caused this problem. So, in Chinese budget models (according to statistics, most often in Alcatel and Xiaomi), the incorrect functioning of the touchscreen occurs as a result of low-quality assembly of the device and a cheap resistive display, which is known to be vulnerable to the accumulation of static charge on its surface. Dropping a smartphone or pressing hard on its screen can also cause trouble with the touchscreen.
However, you should not despair. Before claiming that screen errors arose due to hardware damage, you should try to fix this problem using software methods. Let's consider them in more detail.
How to eliminate the spontaneous operation of the sensor programmatically
So, let's look at several ways to solve this problem on our own.
Method 1: factory reset your smartphone
Depending on the smartphone model, the restoration of the “default” functioning parameters is performed in a certain settings section. However, the path to them is the same for most devices, only the names of these blocks differ. Therefore, let's consider how to perform a factory reset, using the Philips S326 smartphone as an example.
Method 2: Screen Calibration
Recalibration of the touchscreen may be needed not only in the event of a software failure, after which the sensor on the smartphone clicks by itself. After the fall mobile device from a height, getting it into the water, replacing the display, etc. calibration must be carried out without fail - this can help in most of the cases listed here. Let's consider two methods that allow us to carry out this procedure.
Screen calibration using standard tools built into the smartphone
In those models of devices that have the ability to determine the angle of inclination of the touchscreen in the standard functionality, you can calibrate it without using special utilities. For this:
- Go to the "Settings" section of our device;
- In the block "Display", "Screen" or "Accessibility" we find the item "Calibration" and click on it;
- In the next window, it is suggested, as a rule, to put the phone on a flat surface and start the calibration procedure, then your device will automatically adjust the optimal touch angle and complete it.
Using the dedicated app "Touchsreen Calibration"
This method is suitable for those whose smartphone models do not have built-in screen calibration tools. The application compares favorably with similar ones, primarily due to its ease of use, as well as the very high accuracy of determining the angle of inclination of the sensor.
- So, to calibrate the screen using Touchscreen Calibration, you need:
- Download the app from the Google Play link - https://play.google.com/store/apps/details?id=redpi.apps.touchscreencalibration ;
- After installation, we launch the program, in the start window we see the inscription “Calibrate”, framed in a blue background, you need to click on it;
The calibration procedure begins, during which it will be proposed to adjust the angle of the screen in six different touch modes, we go through each of them;
Do not forget that the smartphone must be on a flat surface all this time so that the calibration is as accurate as possible.
At the end, you will be prompted to reboot the device for the changes to take effect.
Here we click "Ok" and reboot the device in order for the changes to take effectConclusion
If the above methods did not help you fix the sensor pressures, then the problem most likely lies in the hardware of your smartphone. There are several hardware reasons due to which the touchscreen may work spontaneously:
- Resistive display - this type of screen differs from capacitive ones in that it is a layer of glass on which a flexible membrane is applied; as a result, such a touchscreen wears out quickly;
- Poor quality of double-sided tape - Chinese manufacturers, and some service centers that repair displays by replacing it, like to save on double-sided tape, which is used to fix the screen inside the case. As a result, the touchscreen does not work properly.
For the above reasons, it is better to entrust the matter to a specialist than to try to repair the screen yourself. If you still want to do it on your own, I recommend viewing these touchscreen repair guides:
After touchscreen smartphones pushed push-button phones out of the gadget market, users faced a new problem. The sensor can blunt”, do not respond to requests, or even during a touch, open something that the user did not need, as if displacing him. In order to avoid such problems, the sensor needs to be calibrated.
Before you calibrate the sensor on Android, you must be sure of the accuracy of your actions. First you have to check the smartphone for a touch error. Turn on, for example, a message and press certain letters. If what you clicked appears on the screen, then calibration is not required. Well, if the characters are different, then you need to configure the smartphone.
It is necessary to calibrate the sensor:
- Every month or two of using a smartphone (if there are obvious changes in the behavior of the display)
- Sticking glass on the display
- Having bought a smartphone with hands or a new one
- After falling, flooded with water
- After changing the touchscreen and screen
- After changing the protective film
How to manually calibrate the sensor on Android
Here it is worth saying right away that a large number of gadgets can be configured in a completely different way, and perhaps you are the owner of such a smartphone. The manufacturer can change or completely exclude this setting in the smartphone. Below we consider the option of setting the calibration in the usual way.
- Enter the settings, and there go to the "Phone settings" tab.
- Enter the "Phone Calibration" tab.
- After that, a cross with a target will appear on a white background in the middle of the screen. Triple click on it.
- After that, the calibration will be completed. After that, check the sensor in the way indicated earlier.
Applications
If the smartphone does not have the ability to adjust the screen calibration, then you can use a special application. At the same time, it will be identical, as in the standard version, and you will need to do the same as in a smartphone with such a built-in feature. Some similar applications give the ability to adjust 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 recommend specific programs for you, as different devices they will show themselves differently. BUT, I will personally recommend the applications I used!
Android device can be customized by most different ways, and in particular, many utilities have been created to help with such a simple matter. "MachScreen Calibration" is probably the most popular program in this case. Also, “Touchscreen Calibration” is an equally popular and simple sensor calibration option.
Android screen calibration through the engineering menu
The most reliable and surest way to get your screen working properly!
- Go to "Challenges"
- Enter a special code (on different models, it may differ, try it)
- *#*#3646633#*#* , *#*#4636#*#* ,*#15963#* or *#*#6484#*#*
- Next, we find the item with screen calibration (different variations on different versions of Android, something with "Sensor"
- After going to the calibration submenu, press start
- If everything is done correctly, you will see the result of the calibration
Now in pictures. An example of entering the engineering menu is given on Xiaomi Mi5.
This code came up on my phone. We are looking for an item with a calibration, in my case it is number 9. Press "Calibrate"
If none of the above access codes to the engineering menu fit, then watch the video instruction, it will definitely tell you the right direction!
Many owners of Android devices with a touch screen often face a problem when the screen does not “listen” to them. That is, when you touch the touchscreen with your finger or stylus at one point, the phone perceives it as touching absolutely another. Or the sensor completely executes orders only from 3-4 attempts. And most likely the cause of these problems is the incorrect operation of the screen, and in order to fix it, you need to calibrate the touchscreen of the Android device.

What it is?
Screen calibration is the adjustment of the touch display so that commands are correctly executed when touched with fingers or a stylus. Of course, you can work with your device without such a setting, but then get ready for wasting your nerves, time and other troubles.
This procedure is required in most cases after the phone has been dropped, especially in water. Screen replacement, a water stain underneath, even the smallest damage may require urgent adjustment. Checking if you need calibration is as easy as shelling pears. To get started, remove the protective film to make the sensor work as clear as possible, then simply enter any number or letter. If you chose, let's say "B", and "A" appeared on the screen, then be sure - you need to set up the touchscreen.
In the production of Android devices, two main types of screen are used: capacitive and resistive. Capacitive is now used in the vast majority, as it is more reliable and of high quality. But with resistive often there are problems, and it requires tuning more often. But the good thing is that now these are rarely used - only in outdated or budget models.

How to calibrate the screen on Android?
Customization using special programs
In free, and most importantly - in free access, you can find a lot of software for screen calibration. They are easy to set up, operate and, most importantly, deliver results. For example, Clinometer, TOPON, Bubble - just take a look at Google Play. But? even if you do not have access to Google Play, you can adjust the display without it using the second method.
Self-configuration
In order to independently adjust the touchscreen of Android 4 (or another version) without any problems, we will present you with step-by-step instructions:
- The first step, of course, is to go to the Settings menu.
- Next, select "Phone settings".
- We find the item "Calibration" and a cross-target with a dot inside will appear in front of you.
- We make money in the center of the target several times (3 will be enough).
- After that, your device will remember the touches and the calibration can be considered complete.
- After completing the setup, check the operation of the sensor. If exactly the symbol you clicked appears on the screen, then everything is done correctly. Congratulations! ()

Contacting the service center
Now you know two ways to calibrate the screen on your Android device yourself. But there is a third option for setting up your device - this is an official or private service center. It would seem, why turn to the master for such a trifle? But such a problem is not always a trifle. It happens that the cause of the breakdown is not in the downed settings, but in a serious breakdown or in the factory defect of the display. In this case, it is really better to contact the service if the first two did not work.
Like any device, the phone sooner or later starts to break down and fail. There are a large number of problems that can occur on Android. One of them is the inadequate response of the screen to pressing. If the sensor of your Android device does not correctly perform the tasks assigned to it, then most likely the screen calibration settings on the phone have gone wrong.
What does "screen calibration" mean on an Android smartphone or tablet
Screen calibration is the device's touch screen settings. That is, if you swiped your finger or stylus over the display, it should reflect your movements with great accuracy. In the event that your actions and what ultimately happened on the screen differ, you should calibrate the device again. Calibration-related problems may occur when replacing the screen, changing device settings, or due to software and physical damage to the device.
Android screen calibration - step by step
There are several ways to calibrate Android devices. Some lead through programs that were originally installed in the phone, others will require downloading special applications from the Play Market. Let's start with those that require as little action as possible.
Via device settings
Since users often experience problems with calibration, the developers have added the ability to calibrate the device through the device settings:
Android touchscreen calibration through the engineering menu
On Android devices, there is a special menu, thanks to which you can do many things that are not available in normal mode.
Via Touchscreen Calibration App
In the Play Market, you can find many applications responsible for screen calibration, one of them is Touchscreen Calibration.
Through the Quick TuneUp App
This application performs the same tasks as the previous ones, but in a different way.

How to set up an accelerometer or G-sensor
Also on all modern devices there is an accelerometer, which determines the position of the phone relative to a flat horizontal and vertical surface. This feature is used in many games, most often racing, when you control the car by turning the phone, and in some other applications.
Through a special application - GPS Status & Toolbox
You can calibrate the G-sensor using free application from Play Store:
Via Engineering Menu
There is a second way to calibrate the G-sensor - through the Engineering Menu:

What to do if the sensor works spontaneously
Sometimes it happens that the screen at some points starts to be pressed by itself. This can happen if the touch glass has been damaged, causing it to adhere too tightly to the display in certain areas. In this case, you need to carry the device to the service and ask to replace the glass with a new one. Touch screens are divided into two types:
If the screen no longer accurately displays what you want to do, then it's time to re-calibrate the display. If the phone reacts incorrectly to a change in its location in space, then it is worth calibrating the G-sensor. And only if all the previous settings did not help, then you should think about changing the touch glass, which could break or be scratched.
