Actions that involve calibration include adjusting the touch screen so that the device correctly executes certain commands by touching the sensor with your fingers. Of course, the device may well work without this procedure, but the owner should prepare for the fact that he will have to observe all sorts of failures when working with the sensor. Next, we will consider in detail the main points that are associated with calibration and the methods that allow this procedure to be carried out.

Why calibration is necessary and what it can fix

Calibrating the screen of an Android device is most often necessary after a phone has been dropped or other mechanical damage has occurred. It is also necessary if the display had liquid contact- this, as a rule, violates the susceptibility of the electrodes, despite the fact that most gadgets are equipped with capacitive screens. They have replaced resistive ones, and are more reliable and more sensitive.

For what reasons debugging required:

• the sensor does not correctly recognize commands. In this case, for example, a tap works fine, but a pinch or a swipe can work periodically;
• The touchscreen doesn't always work. Actions may not be recognized and devices may ignore them;
• incorrect definition of commands. In this case, you can specify the letter "A", and "B" will be displayed instead;
• the waiting time for a response to an action being performed has increased significantly;
• Some graphics applications may experience interruption in selection of certain areas of the image or lines being drawn.

Consider when such problems occur:

• phone is used in for a long time. This is the main reason why the sensitivity of the sensor decreases, it is associated with physical factors. Also, this in detail directly depends on what quality the touchscreen is installed. However, it is important to note the fact that such failures can occur due to prolonged inactivity;
• sensor initially configured incorrectly. To avoid problems, we strongly recommend debugging immediately after purchasing the phone. Also, after replacing the elements of the touchscreen, calibration is required;
• viral activity and changing system settings. In some cases, incorrect operation is caused by virus activity or the user accidentally set the sensitivity parameters in the phone settings (some gadgets provide this function);
• mechanical damage screen. Scuffs, scratches, improper application of a protective film, drops and a broken display significantly reduce the sensitivity of the sensor. Screen contamination also applies to this item.

Calibration using Android

You can debug using the standard tools of the Android operating system:

A small utility that allows you to optimize and adjust the sensitivity of the sensor. Display calibration has an intuitive interface and a set of settings on display debugging.

Instruction:

Calibration via computer

If the sensor does not respond to commands or failures occur after calibration, then in this case it will be necessary to perform optimization via a computer. To do this, we need to install the program - MSP RemoteAlignment.

Utility features:

• calibration without installing software on the phone;
• saving the procedure log on the computer;
• debugging the touchscreen and saving the log with the results.

After the software has been installed, we proceed to the process itself:

• run the program and a window will appear on the screen, where several tabs will be presented;
• then connect the phone to the computer using USB;
• if you need to perform automatic debugging, press the "Skip" button, and to carry out all actions manually " Alignment»;
• after the process is completed, you can save the log by clicking the " Retrive».

How to check the touchscreen for performance

After the calibration, you need to make sure that the touchscreen is working, you can do this as follows:

• go to the Play Market and download the Screen Touch Test utility;
• install it on your device and run it;
• a field will appear on the main screen where you need to draw a rectangle right around the perimeter of the screen;
• when the sensor works correctly, the line will be smooth and clear, without breaks. If deviations are observed, the line is interrupted, various kinds of dots appear, this indicates that the touchscreen is unstable.

A similar function is available in the standard settings of Android.

Checking and adjusting the sensitivity

Additionally, you can use special features and independently adjust the sensitivity of the sensor:

How to Calibrate the Screen on an iPhone

On iPhone, you cannot perform the usual calibration that is done on Android. There are no special programs for this, and there is no advanced functionality in the settings. Therefore, one can only auto brightness sensor optimization. You can do this in the following way:

• open "Settings";
• we are looking for a room where the light is the dimmest;
• in the list of options, select the tab " Display and brightness»;
• deactivate the option " Automatic brightness»;
• a slider will appear with which you need to adjust the brightness of the screen, reduce the parameter to the very minimum;
• then reactivate the parameter " Automatic brightness” and the display becomes much brighter. The sensor will correct this option and move the slider to the optimal position.

Proximity sensor calibration

Proximity sensor - is a proximity sensor. This is a small device that reacts to the physical proximity of the smartphone to any object. It is thanks to him that the screen turns off during a telephone conversation.

Instruction:

Program for optimizing the sensor "Proximity sensor: Reset":

• downloading the program from the application store;
• press " Calibrate Sensor»;
• close the upper part of the device (the location of the sensor) with your hand and click "Next";
• remove your hand from the sensor and click "Next" again;
• then tap "Calibrate" and confirm the execution of the actions " Confirm". We reboot the device.

Possible Calibration Issues

Touchscreen optimization may not help in the following cases:

• in the first place is hardware failure phone. One of the options is damage to the screen with cracks that have arisen in the process. In this case, calibration will no longer help, you must contact the service center to replace the sensor;
• manufacturing defects. In some cases, we can talk about a factory marriage. The touch panel may not fit snugly against the glass, somewhere it comes close to it, somewhere not. In this case, spontaneous operation or lack of response is observed in some areas of the screen. Here you will also have to contact the service center.
• Incorrect repair. After replacing the touchscreen, the sensor may not work or work poorly. This also includes the mirror work of the touchscreen, when all actions and touches are mirrored on the display. It is not possible to determine the breakdown yourself here. It is better to take the device to the service center that carried out the repair. Usually in such cases the sensor is connected incorrectly.

A fairly large number of users of devices with the Android OS are faced with incorrect display operation. In other words, while pressing a finger on the screen at a given point, the device responds by turning on some function in another place. Or the touch display executes the command only after a few taps on the same position. It is more likely that the main cause of this problem is the incorrect operation of the display itself, and in order to correct the situation, you will need to adjust the touchscreen of your smartphone.

What it is?

Display calibration is a special setting of the smartphone screen, which serves to adjust the accuracy of the execution of commands while pressing. I must say that you can use your smartphone without these adjustments, but in this case you need to be prepared for regular errors and other problems.

Setting up the touch part of an Android device is most often needed after a hard fall of the smartphone. Installing a new display, a wet spot under the screen, or subtle damage may require immediate attention. Finding out if your device requires such a setting is very easy. Before starting, peel off the protective cover, if you have one, so that the device works as accurately as possible, then just tap on any character on the keyboard. If you pressed the number "3", and at that time the display showed "4" or "2", then you can say for sure that you need to adjust the screen urgently. I must say that along with calibrating the accuracy of the screen, you may need to adjust the sensitivity of pressing the display. We will also describe this procedure in detail.

Android smartphones currently use two types of screens: resistive and capacitive displays. The second type is most often used today, as it is more in line with the protective characteristics. But with the first representative, problems occur, and it requires adjustment more often than capacitive. But at the moment, such displays are installed very rarely - only in very cheap devices or obsolete ones.

How to calibrate the screen?

Today, there are two methods for how to fix a malfunctioning sensor - a hand-made method and separate utilities. It must also be said that for devices from Samsung, Sony, Nokia, and other Android devices, the screen calibration process is no different.

Customization using special programs

In the vast Play Market today you can find a bunch of special utilities to carry out this procedure. They are not particularly difficult to work with and are extremely effective in use. For example, programs like TOPON - just go to Google Play and you will find what you need. But in the event that you do not have Internet access, then you can always set up the display without it, using the second method.

Android sensor calibration: programs, setup: Video

Self-configuration

To manually calibrate the display on Android version 4+, we will show a step-by-step guide:

1. We go to the "Settings" of the device.
2. Go to the "Phone settings" section.
3. We select the “Calibration” category, after which a cross with a dot will appear in front of us.
4. Tap directly to the center of the cross 2-3 times.
5. After touching, the smartphone will remember the command and complete the calibration of the device.

After completing the adjustment, check that the screen debugging is correct. If the display shows the symbol that was pressed, then the work has been completed successfully.

Contacting the service center

Now you know the most effective ways to fine-tune the screen on your Android device. But I also want to say about the third type of setup - this is the official one, which consists in going to the nearest service center. You may ask why you need to go to the service to fix such a problem? But this problem is not always corrected by improvised methods. It happens that the cause of the problem is not incorrect settings, but a factory defect or a system failure. With this outcome, it is best to run to the service if the listed methods did not solve the problem.

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:

1. Remove the special film protecting the screen (to ensure the most correct operation of the sensor);
2. Enter any letter or number;
3. 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 Google Play assortment, the display of an android device can be configured in another way without any special problems.

The step-by-step instruction in this case may look like this:

1. Go to the gadget in the "Settings" menu;
2. Select the item “Phone settings;
3. Find the inscription “Calibration, press the button;
4. A cross-target will appear on the screen, which has a dot inside;
5. 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 configure the sensor using 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
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 launch, select the type of device screen orientation in the settings (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 turn on the complete ignoring of 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 an appeal to a 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.

Smartphones and tablets based on Android OS have one similar problem for many users.…

Sensor calibration on Android - adjusting the sensitivity of the screen of a tablet or smartphone Many owners of Android devices consider the sensitivity of the sensor to be a pain point of their gadgets. It happens that the screen of a phone or tablet reacts incorrectly to pressing. For example, if the user taps on the lower left of the screen, the sensor interprets this as tapping on the upper right corner. But the problem that has emerged is not at all a reason for despondency and an urgent trip to the service. It is entirely possible to try to "curb" your sensor at home by applying screen calibration. What is calibration Screen calibration (aka: sensor calibration) is a display setup, the purpose of which is to optimize performance and improve sensor response to pressing and touching with fingers or a stylus. And although sensor calibration on Android is generally not necessary, it is recommended for all users of devices with both resistive and capacitive touch displays. It is advisable to calibrate resistive screens immediately after purchasing the device. With a capacitive sensor, the situation is somewhat different, as it is possible to check if calibration is necessary, or if the display will work clearly without such an operation. To do this, you need to remove the film from the gadget screen, wipe it with a damp cloth (preferably a special one), and then check the sensor response. The best way to check is typing a text message. If frequent typos appear during typing, this is a sign of the need to calibrate the touchscreen. It should also be noted that it is quite possible that this procedure will have to be done more than once. Before proceeding with the screen calibration procedure on Android, you need to find out what caused the sensor to malfunction. It is quite possible that the pie eaten with tea left you a reminder of yourself in the form of traces left on the screen when answering an urgent call. The proximity sensor or Air Gesture function is not working properly. Using custom (not official) firmware. Installing apps from dubious sources. The device has been dropped, hit, or wet. Touchscreen replacement, etc. As we well know, it is necessary to eliminate the cause, not the effect. It is clear that if your smartphone has a “left” firmware that caused the failure, you can calibrate the sensor to the “carrot pen”, but the desired result in this case will not be achieved, alas. Nevertheless, even if the device does not need calibration, it will not hurt its owner to know the intricacies of setting the touchscreen, since this is a fairly simple manipulation that does not require much time, and even more so a huge layer of knowledge. How to calibrate the sensor on Android To calibrate the screen of any device running on the Android operating system, you can use special programs and utilities, of which there are a sufficient number, and absolutely free. You can also access the standard services located in the device menu. Manual setting Here you need to clarify that the setting options, including the screen sensitivity, vary greatly depending on the model of your gadget, and it is quite possible that it will not work in your case. The fact is that manufacturers of mobile devices over the standard settings of the Android OS, as it were, install their own shell, while changing (or completely eliminating) the possibility of a particular setting. The calibration method for devices with standard settings is described below: Go to the settings menu. Select "Phone settings". Go to the "Calibration" menu, which will open a window in the form of a cross-target with a dot inside. Click on the center of the target three times. Calibration is completed. Next, you should check the sensor by the manipulations indicated earlier. If these steps are irrelevant for you, then you need to check on the manufacturer’s website exactly how you can calibrate your device, or use a special application (read about this method below). Using special software At the moment, there are countless utilities and programs that help you set up the touchscreen of your Android device. Of the proven programs that have really helped many users, the following programs can be noted: Touchscreen Calibration - a simple and free tool that can help you quickly and easily calibrate the sensor. Step by step: Download the application, open it, press the "Calibrate" button: Then, start the calibration process by clicking on the gray field on the screen: After that, in the gray field, execute the commands that appear in the green squares. Unfortunately, the utility is not Russified, but what and how to do is shown quite clearly. The principle of operation in all existing applications is the same (enter the application - perform the proposed actions - check the result), so it makes no sense to describe how this is done in one case or another, so we will just mention the most popular utilities. In addition to the already familiar Touchscreen Calibration, these are SGS Touchscreen Booster, Touch Accuracy, and Display Calibration to improve display shades. Choose a tool that is convenient for you and solve your problem quickly and easily. Important: some programs will require ROOT rights. If the calibration did not help If the described methods did not bring results and the screen continues to respond incorrectly to pressing - most likely, the problem lies in a factory defect that occurred during the assembly of the device, and a serious breakdown that cannot be repaired at home cannot be ruled out. In such a situation, you should contact the service center for the help of a qualified technician. Considering that the main element of the vast majority of Android smartphones and tablets are screens on which even the buttons work with the help of a sensor, poor display settings can turn the use of the device into real torture. Of course, you can immediately give the device to a service center, however, having figured out the reason, in some cases, by independently applying the touchscreen calibration, you can try to do it on your own. This simple, fast and absolutely energy-saving procedure will most likely help optimize the performance of the display, and at the same time improve the usability of the entire device.

Over time, the device's touch screen may not respond correctly to finger or stylus touches. This problem is especially relevant for smartphones and tablets equipped with a resistive screen - it twitches and glitches quite often. To troubleshoot, you need to calibrate the screen on Android. This procedure can be performed regularly as a prevention of problems with screen response. It is also carried out after replacing the touchscreen.

There are not so many methods for software calibration of the touch screen, so we will analyze each of them. In the future, you can choose the fastest and most convenient.

Let's analyze the following calibration methods:

• Using the built-in tool.
• Through the Android engineering menu.
• Using multiple third party apps.

On most Android devices, the screen calibration function is built into the standard list of settings.

To use this feature and customize the screen with it, you need to:

1. Go to "Settings" (the icon can be found in the menu or in the right corner of the screen after swiping the curtain).

1. Open the "Screen" or "Display" section (the names will differ depending on the smartphone manufacturer). Here you can immediately adjust the brightness and saturation of the display, the warmth of colors, etc.

1. Open the "Screen Calibration" section. If this tab is missing, then immediately go to the second method.

1. If the function is present, then run it. A test will open, consisting in sequentially clicking on certain areas. However, the test can be anything.

Engineering menu

Screen calibration on Android can be done through the engineering menu. This is a special environment in which you can test all the components of the device and configure settings that are not available in standard mode.

To use the engineering menu, you need to find out the code for opening it. For different devices, the combinations will be different. Here are examples for the most common brands:

• Samsung — *#*#4636#*#*, *#*#197328640#*#* or #*#*8225#*#*;
• Sony - *#*#3424#*#*, *#*#4636#*#* or *#*#8255#*#*;
• Huawei – *#*#2846579#*#* or *#*#2846579159#*#*;
• HTC - *#*#3424#*#*, *#*#4636#*#* or *#*#8255#*#*;
• Most devices running on MTK processors are *#*#54298#*#* or *#*#3646633#*#*;
• LG - *#*#4636#*#*;
• Fly, Alcatel, Prestigio - *#*#3646633#*#*;
• ZTE - *#*#83781#*#*;
• Philips = *#*#333861#*#* or *#*#13411#*#*;
• Xiaomi – *#*#6484#*#*;
• Texet - *#*#3646633#*#*;
• Others - *#15963#* or *#*#364663#*#*.

So, in order to calibrate the screen and its sensitivity (increase or decrease depending on the degree of deviation) through the engineering menu, you need:

1. Open the application through which calls are made.

1. Use the keyboard to type the combination of characters that is suitable for your device (we will use the example of a Xiaomi smartphone on Android 1.2).

1. Go to the "Single Item Test", "Hardware Test" or other similar tab for testing.

1. Select the item responsible for the touchpad, sensor, or the calibration itself. In our case, you need to go to "Touchpal".

1. Start the calibration process and perform the actions required by the system. In our case, it was necessary to swipe several times from a given point to the opposite end of the screen, without touching the borders of the red color.

1. On some devices, you don’t have to do any additional actions - it will be enough to go to the sensor calibration section, click on “Clear calibration”, and then on “Do calibration”. All actions will be performed automatically.

You must restart your device for the changes to take effect.

Third Party Applications

Perhaps the manufacturer has not built into your device the function of calibrating the Android screen, and you are afraid to enter the engineering menu. In such a situation, you can use one of the applications designed specifically for screen calibration.

Such applications work on any device, regardless of screen type, model and brand. Let's consider the best of them.

A fairly convenient tool, the key disadvantage of which is the English-language interface - there is no version in Russian. We will describe in detail the sequence of actions, so that you will not have any problems.

To properly install the Touchscreen Calibration program on a smartphone and fix problems with the touchscreen, we perform the following steps (other applications will be installed in the same way, so the instructions can be considered universal):

1. Open Google Play - the official app store for Android. You won't be able to download programs without registering - you need to create your own account. If this has not been done before, the system will automatically offer to register an account according to the instructions.

1. Tap on the search line and write the query "touchscreen calibration". Let's move on to the first result.

1. Click on the "Install" button. The application can be downloaded absolutely free.

To calibrate the screen if the image jumps and the sensor does not obey, you need to:

1. Enable application from desktop. On pure Android, the icon is in the menu.

1. Click on the "Calibrate" button to start the procedure.

1. Click once in the area on the point indicated on the screen. Wait for the program to display the accuracy of pressing in percent and switch to the next step.

1. Double tap on the dot.

1. Click on the dot and hold for 2 seconds.

1. Put your finger where the dot is, and, without releasing, swipe to the right.

1. Bring two fingers across the area to the selected point in the direction of the arrows (make a “pinch”, which is usually used to reduce the image).

1. Put two fingers in the center and spread them apart (this is how the picture is usually enlarged and its individual elements are approached).

As a result, the program will display a notification that the calibration was successfully completed and the device needs to be rebooted. It remains only to check whether the sensor “slows down” and whether the problem has been fixed.

Please note that after each action, the utility should display the result, which is shown in the screenshot of the phone's desktop below.

Using Touchscreen Calibration, you can perform a fairly high-quality sensor calibration in 6 steps.

Another extremely handy tool that uses a slightly different calibration method. Use this utility if working with the previous one did not give the desired result.

After downloading the application from Google Play to your phone, we perform the following set of actions:

1. Open the application - its icon will be added to the desktop automatically.

1. We find the item "Display Calibration" and tap on it. A check will be made.

1. We are waiting for the application to automatically perform the necessary actions.

1. We receive a message containing information about the result, close it and reboot the device.

With Quick TuneUp, you can calibrate and test almost all device components on your phone - from RAM to all existing sensors. This is relevant when you need to reduce or increase the sensitivity of the sensors.

Service center

Not always inaccurate or accidental clicks occur due to failures in screen calibration - some problems cannot be solved by software settings. Usually, with the help of the methods we have described, only minor deviations from the ideal are corrected.

If the screen of a tablet or smartphone itself clicks on arbitrary areas, then first remove the protective film from it. If this does not help, then you need to try to calibrate the screen using the methods discussed in the article. And, if none of the above methods gave a result, you should carry the device to the SC, since mechanical damage can cause serious disturbances in the sensor response.

Video instruction

We are attaching a detailed video instruction on using all the Android display calibration methods described in the article.

Conclusion

We recommend that you calibrate every two to three months to avoid sensor deviations. In addition, you need to perform such a procedure after installing a protective film and if moisture gets into your smartphone or tablet, as well as after repairing the screen.

Before proceeding with the calibration, make sure that the cause of the problem is not external damage to the screen.
