Calibration of Android touch buttons 4. How to calibrate the sensor on android. Calibration without third-party programs

If your touch screen samsung phone, as well as any other is excessively or not sufficiently sensitive, it works uncontrollable and answers it in a timely manner, you can try several solutions, one of which calibration.

If the device display is protected, make sure that you are correctly installed (no air bubbles under it, dust and moisture).

Wipe the touch screen with a clean, dry cloth, and before use touchscreenMake sure you have clean and dry fingers and hands.

Too high temperature of the device may adversely affect the functionality of your touch. Give it cool, and then try to experience again.

Turn off the tablet, and then turn on again. This will disable all applications and free up the memory that automatically sometimes solves the problem.

Note: If the touchscreen calibration is broken, due to which it has been confused, it can be restored independently according to the scheme described below.

Touchscreen problems in android

You will not be able to reboot or shut down if the display no longer responds or has problems with restarting.

If there is a memory card in the device, delete it and reboot - the SD flash drive may be damaged and adversely affected by performance.

If the device performance in safe mode increases, then one of the applications is likely to adversely affect the operation.

You can get out of safe mode, restart the device applications and uninstall the suspect causing a problem.

If you do not know which applications are the cause of this problem, you must remove the recently downloaded.

Use the Diagnostics application to quickly check the functionality of the touchscreen.

Diagnostics can evaluate potential problems with hardware or software.

Device update provides more high performance and provides the latest improvements.

How to check whether the touch screen calibration on the device Android

If you want to believe that you need to make the screen calibration, you first remove the protective film, and if it is not, then clean it with a soft cloth or a special napkin.

Now check the degree of response touching it: if it appeared on the screen not what you wanted to call, then calibration is needed.

Even when buying a new touch phone Or the tablet sometimes you need to calibrate the touch screen or if it works incorrectly.

Sensor calibration on android

Android phones with touch screens today are available to everyone. They practically crowded old push-button.

The most popular OS is Android and its screen is sometimes required to calibrate, the efficiency of using a smartphone or tablet after that is usually growing.

Calibration of the sensor Android necessarily need if the phone does not respond incorrectly to the touch of fingers.

It may also happen after the fluid fall into the device falls. Then in many cases without a wizard can not do.

Regardless of the manufacturer Samsung, HTC, Lenovo, LG or MEZ, the tuning screen setting is the same.

To make calibration, you need to enter the menu and go to "Settings", make scrolling down and select "phone settings".

There to choose the "Calibration" item and follow the instructions provided. Before calibrating, put the device on a flat surface and only then spend it.

Overall, contrary to visibility, calibrate the touch screen Android is not difficult. This can do any, including the one who is not considered well acquainted with new technologies, can actually succeed without problems.

In some androids, the screen calibration can be in the Language and input section (depending on the smartphone, tablet and android version).

ATTENTION: The calibration option is not present on all devices, so you may not even find such a tool, but for this there are other efficient methods.

There are many ways to check the touchscreen phone or tablet running android.

The easiest way to upload the application for this purpose and use it to check. One of the best free multitouch test that recognizes the user's touch.

If necessary, you can also check the number of strokes that supports the display by clicking on the screen with several fingers simultaneously.

Each time you do the pressure on the display, color circles should appear, indicating that the touch was correctly recognized.

To view information about the number of simultaneous points, the number of taps and frames of frames per second, look at the statistics in the upper left corner of the application.

Programs for calibration touchscreen Android

The described method above is not always suitable and not for all devices, and the accuracy is not always satisfactory.

Programs work more effectively. One of them "Touchscreen Calibration",

There is also an option - tweaker, for fine tuning system, only may be required by the right of the superuser (ROOT rights).

Calibration allows you to increase sensitivity and use an android phone or tablet to the maximum.

Note: You certainly not be able to get something supernatural, but you should notice the difference immediately. Successes.

After the sensory smartphones ousted push-button phones From the gadget market, users faced with new problem. Sensor can " bang", Do not respond to requests, or even during touch, open not what you needed to be the user, as if shifting it. In order to avoid such problems, the sensor needs to calibrate.

Before calibrating the sensor on Android, you must be sure of the accuracy of your actions. First you have to check the smartphone on the touch error. Turn on, for example, the message and press certain letters. If the screen appears that you have pressed, the calibration is not required. Well, if others are symbols, then you need to configure the smartphone.

It is necessary to carry out the sensor calibration:

• Every month, or two, the use of a smartphone (if there were explicit changes in the display behavior)
• Planting the glass on the display
• Having bought a smartphone with hands or new
• After falling, filled with water
• After changing the touchscreen and screen
• After shift protective film

How to calibrate the sensor on android manually

It costs to immediately say that a large number of gadgets can be adjusted completely differently, and perhaps you are the owner of such a smartphone. The manufacturer can change or exclude altogether this setting in a smartphone. Below will consider the calibration setting option in the usual way.

1. Enter the settings, and go to the "Configuration of the Phone" tab.
2. Enter the phone Calibration tab.
3. After that, on a white background, a cross with the target appears in the middle of the screen. Click on it three times.
4. After that, the calibration will end. After that, check the sensor specified by the method previously.

Using applications

If the smartphone is not able to configure the screen calibration, you can use a special application. In this case, it will be identical as in the standard version, and it will be necessary to do the same as in the smartphone with a built-in such possibility. Some similar applications give the ability to customize more accurately than "relatives".

To search for such applications, go to Google Play. Through the application, and enter the "Calibration of the screen" in search, and then select the desired one. Unfortunately we cannot advise you certain programs, since different devicesoh, they will show themselves in different ways. But, I advise my applications used personally!

The Android device can be configured in many ways, and in particular, many utilities have been created that will help in such a simple matter. "Machscreen Calibration" is probably the most popular program in this case. Also "Touchscreen Calibration" is no less popular and simple Sensor calibration option.

Android screen calibration through engineering menu

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

• Go to "Calls"
• Enter a special code (on different models, it can differ, try)
• *#*#3646633#*#* , *#*#4636#*#* ,*#15963#* or *#*#6484#*#*
• Next, we find a point with a screen calibration (different variations on different versions Android, something with "Sensor"
• After switching to the calibration submenu, press the start
• If everything performed correctly, you will see the calibration result.

Now in pictures. An example of login to the engineering menu Xiaomi Mi5..

On my phone came up this code. We are looking for a point with calibration, in my case it is number 9. Press "Calibrate"

If not one of the above access codes of the engineering menu does not come up, then look at the video instruction, it will definitely tell you the right direction!

Many owners of android devices consider the susceptibility of the sensor with a painful point of their gadgets. It happens that the screen of the phone or tablet is incorrectly reacts to pressing. For example, the user clicks on the left side of the screen, the sensor also treats it as pressing the right upper angle.

But the designated problem is not at all reason for despondency and urgent hike to the service. It is possible to try to "curb" your sensor at home, applying the screen calibration.

Screen Calibration (It: Sensor Calibration / Sensor Calibration) Calculate the display setting, the purpose of which is to optimize the operation and improving the response of the sensor to press and touch the touch or stylus .

And although the sensor calibration on Android is generally not a necessity, but it is recommended to all users of devices, both with resistive and capacitive touchscreen display. Resistive screens are desirable to calibrate immediately after the acquisition of the device. With a capacitive sensor, the situation is somewhat different since it is possible to check whether the calibration is needed, or the display will work clearly and without such an operation.

To do this, from the gadget screen you need to remove the film, wipe with a wet cloth (preferably special), after which you check the sensor reaction. The best way Checks - set text message. If there is frequent typos when set - this is a sign of the need to calibrate the touchscreen. It should also be noted, it is possible that this procedure will have to do more than once.

Before entering the procedure for calibrating the screen on android, it is necessary to find out what caused the sensor improper operation.

• It is possible that the cake eaten with tea left you a reminder of yourself in the form of traces remaining on the screen when answering an urgent call.
• The approximation sensor or the Air Gesture function works incorrectly.
• Use custom (not official) firmware.
• Installing applications from dubious sources.
• Fall, blow or moisture hit on the device.
• Replacing the touchscreen, so on.

As we know well - to eliminate the reason, and not a consequence. It is clear if the firmware that was the cause of the failure was installed on your smartphone, you can calibrate the sensor to the "Carrobine Change" only the desired result in this case will be achieved, alas, will not.

However, even if the device does not need to be calibrated, its owner does not prevent the need to know the details of the touchscreen setting, as this is quite simple manipulation that does not require much time, and even more so a huge reservoir of knowledge.

To calibrate the screen of any device operating on the operating room android system, you can use special programs and utilities that exist enough, and absolutely free. You can also refer to standard services in the device menu.

Manual setting

Here you need to clarify that the ability to set up, including the sensitivity of the screen, is very different depending on the model of your gadget, and it is quite possible that it is in your case it will not fit. The fact is that manufacturers of mobile devices on top of the standard OS android settings as if installing their own shell by changing (or completely excluding) the possibility of one or another setting. The following describes the calibration method for devices having standard settings:

1. Go to the settings menu.
2. Select the "phone settings" item.
3. Go to the "Calibration" menu, where the window will open in the form of a target cross with a point inside
4. Press the center of the target three times
5. Calibration completed. Next, check the sensor by the manipulations specified earlier.

If these actions are irrelevant for you, you need to be clarified on the manufacturer's website, how exactly your device can be calibrated, or to use a special application (read about this way below).

Application of special software

On the this moment There are countless utilities and programs to help configure the touchscreen of Android devices. From the proven programs that really assisted a variety of users, such programs can be noted:

Touchscreen Calibration - Simple I. free toolwhich can help quickly and uncomply calibrate the sensor. Step-by-step actions:

Download the application, open, click the "Calibrati" button:

Then, run the calibration process by pressing the gray field on the screen:

After that, in the gray field, we carry out teams that appear in green quadraticles:

Unfortunately, the utility is not Russified, but what and how to do it is pretty clear. Just in case we offer more watch a video

Although sensory devices are very convenient, over time, the work of the sensor may lose accuracy, and this, in many cases, does not depend on the type of screen, no on the brand and model of the device.

In this regard, any such sensor (and screen) is sooner or later debugging or calibration. This article describes how the calibration and the screen setting on android is performed.

The essence of the problem

It is known that while the phone or tablet is new, then the quality of the sensor is very high. It quickly responds to touch, quite accurately determines the point to which the user pressed, etc. But over time, as the actual life of the device increases, the quality of the sensor is significantly reduced, and errors and inaccuracies begin to occur.

How to understand that you need to calibrate the display on your mobile device? Usually, do it comes from when starting the following types of errors appear significantly interfering to work:

• Sensor does not always work - some actions are not recognized and the device does not react in any way;
• Do not recognize or badly work some types of actionbut not all (for example, tap can work fine, while brightness - it works not every time or vice versa);
• Not exactly determines the actual location where the action was made (for example, not the button is pressed to which you actually touched);
• Significantly increased response time after a work of a particular action on the touch screen;
• It became worse to work the display only when using the stylus, or, on the contrary, only when using your finger;
• IN graphic applications Such a problem may manifest as interrupt drawn line etc.

The emergence of such a problem is essentially a normal and natural process, the consequences of which can be easily eliminated by basic means, that is, without attracting the service.

When does it occur?

Long operation of the device - The first reason that the quality of the sensor on the phone or tablet will gradually fall. This is a normal process that all modern phones are subject to the greater extent, the less high-quality screen is installed on the device. Also, such a phenomenon occurs and, on the contrary, with too long inactivity of the device, which was previously actively operated.

In some cases, such debugging screen is required immediately after purchase, as it happens that initially, the sensor is configured incorrect. After changing the display, it is also necessary almost always.

Changes in software settingsAlso affect the quality and speed of the sensor. These can be any viruses or other software problems, and there may be settings, consciously or accidentally modified by the user. For example, sensor sensitivity can be changed for the convenience of working in the phone settings.

But, reducing the quality of the device can occur for other reasons. For example, this happens when scratching and scratching on the screen appears, applying a poor-quality protective film or while maintaining bubbles under it, etc. In this case, the calibration will not be quite effective and the problem will not eliminate.

Definition

What is calibration, and how does it solve the problem of a unusual or inaccurate sensor? Calibration is a touchscreen setting, produced by the device based on the actions with a sensor performed by the user.

The standard calibration procedure is performed as follows.: The screen shows the points, circles or crosses in an arbitrary order and the user must press them.

Based on this process, the system builds a specific scheme of points and sections on the screen, which is thus determined which of them more responsive, which are less, for what accuracy is higher ones below. According to such diagnostics, the system makes adjustment and troubleshooting.

Cut the calibration of the same device to which you work on it most often. If you are more often using the stylus, then calibrate the screen them, if you, usually, use the phone manually, then spend the calibration with your finger. This is due to the fact that different items are different thermal conductivity and the display can react to them a little different from a technical point of view.

<Рис.2 Калибровка мультитач>

Calibration methods

Conduct such debugging in several methods. The most simple and effective of them are described below. If, after applying a method of significant changes, it has not happened for the better, it is advisable to try to apply another method.

Device settings

Since the calibration of the device is a necessary process, the creators of most devices on the Android system laid such a function in the device settings. How does it take advantage of?

1. Go to Device settings;

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

<Рис.3 Настройки>

3. Go to the section Screen calibration/ calibrate the screen or similar (notice that there is no such partition on some devices at all, this suggests that debugging will have to be performed in a different way);

<Рис.4 Экран>

4. If there is such a function, then after pressing it will start a special testin which you need to press for certain points as they appear or in a certain order (on different devices, the procedure for conducting the test may change slightly, but one) remains the essence);

<Рис.5 Тест>

After completing all the necessary actions, the system will show you a notice that the test is over, Now section Settings You can close.

Sometimes significant improvements in the work of the sensor are observed right immediately after that. But in most cases, the tablet or smartphone must be reloaded.

Engineering menu

Engineering menu - This is a special setting section in which you can spend more complex and more accurate debugging and adjustment. In any case, there is a calibration function, for example, on those devices that this test is not submitted to a simple device settings menu.

In order to access the engineering menu, you need to perform a number of actions:

1. Open the application Telephone on your device;

2. Type one of the special numbers (for different devices, they are different, everything works on some, therefore it makes sense to try each code in turn until it gets the one that works) - *#*#3646633#*#*, *#*#4636*#*, *#15963#*;

<Рис.6 Вызов меню>

3. Click the call button is not needed, after the last sign of the appropriate combination, the engineering menu will open in itself - go to the top ribbon in the Hardware Testing section;

<Рис. 7 Инженерное меню>

4. Opened after this menu is scrolling down to the point. Sensor And go to it.

<Рис. 8 Сенсор>

5. Now launch the calibration itself - for this, go to the section Sensor Calibration.

<Рис.9 Настройка>

6. Find the section in the calibration menu Clear Calibration and click on this button to reset the old sensor settings;

<Рис.10 Сброс настроек>

7. Now press the button DO CALIBRATION 20%If you want to set up the maximum sensitivity of the screen and 40% - if a bit smaller;

<Рис. 11 Запуск>

8. Do not do additional preservation - Just leave the engineering menu by pressing the button. Back or Home;

<Рис. 12 Выход>

9. Restart the device.

After re-enabled the phone, the problem must be completely eliminated. The sensor should work clearer. And this method gives.

Often, the best result than calibration using the test in the phone settings, therefore it can be carried out and in the case when after the test in the settings for a significant improvement of the state of the sensor, the user was noted.

Using applications

If the calibration is not submitted in the device settings menu, if the engineering menu has not opened (sometimes sometimes happens), or if the calibration quality has not arranged, you can download special applicationwhich will help perform the debugging of the sensor. It extends free of charge in Play Market..

Download and install Touchscreen Calibration

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

• Open play application Market. on your device;

<Рис. 13 Гугл Плей>

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

<Рис. 14 Скачивание>

After that it automatically jumps and will be established.At the same time, the label will be created on the desktop of your device.

<Рис. 15 Иконка>

Now the application is installed on your device, and you can start using it. It takes not a lot of memory and applies for free.

The load on the hardware resources of the phone is moderate or minimum (depending on technical characteristics devices).

Using Touchscreen Calibration

As mentioned above, the label to start this application is on Desktop Your device. Run it from there. It should open immediatelybecause it does not require large number random access memoryTherefore, it starts without hanging and failures.

• In the main menu of the application find a big blue button Calibrate and click on it;

<Рис. 17 Запуск>

Perform all the actions offered by the program - It will also be, as in the first way, test at points, while different types actions - tap, double tap, long press, etc.;

<Рис. 18 Тест>

After performing all actions a notification appears on the screen that the process is successfully completed.;

<Рис. 19 Завершение>

Now you can close the applications by any familiar way.

Appendix Quick Tuneup.

This application is largely similar to the previous one. In fact, they both perform the same goals, but use different methods for this with hardware and software points.

Because if, after work in the previous program, there was no significant change in the quality of the sensor, it makes sense to download this application and try to correct the situation with it.

You need to download this application as well as the previous one, just enter a different combination in the search engine in Play Market, namely Quick Tuneup. After clicking on the Install button, the application automatically jumps and will be installed on your device. You can find a shortcut for its launch on the main desktop.

<Рис. 21 Ярлык приложения>

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

<Рис. 22 Функционал>

3. Now you need to wait a bitsince this process is not presented as a dough at points, but in the form of automatic search faults, and then - automatic debugging screen;

4. When starting the process, on the main screen of the application will be a notification showing the progress of debugging;

<Рис. 23 Процесс калибровки>

When the process is completed, you will only need to restart the phone..

After re-inclusion, no difficulties with the work of the sensor should be.

Other malfunctions

In some cases, errors in the work of the sensor may also have a different character. For example, this situation is common when at certain points the screen periodically triggers spontaneously.

This happens in cases where the screen of the screen is seriously damaged, it bends and at some points adjacent to the screen too tight, causing the sensor.

Outside, such a problem may be invisible at all.. Nevertheless, it is quite complicated and requires correction under the service center. Usually, in such cases, a complete replacement of the display glass is recommended.

Also in the service center should be treated and then when none of the listed calibration methods did not help. It can also say that the quality of the sensor work has decreased due to the damage to the glass or faults in the hardware of the device.

A huge role for modern phones Plays touchscreen calibration. Android is the operating system that will be discussed. It is with her to work further. Touchscreen setting on "Android" can be carried out in several ways. Each person himself decides how to spend it. But what options are possible? What you need to know about calibration? All this will be told below. In fact, everything is much easier than it may seem at first glance.

Calibration is ...

To begin with, it is necessary to understand what the Android touchscreen calibration is. What is this process? Touchscreen calibration is called the screen configuration for the correct response to the commands sent by the user. Of course, you can do without it. But then, over time, the smartphone will be responsible for a long time to send commands, as well as displaced the press on certain sensory buttons.

Most often calibration is needed:

• after replacing the touchscreen;
• when the smartphone falls;
• after system failures;
• if all the gadget settings have been reset.

It does not matter what caused the sensor setting. The main thing is that the Android touchscreen calibration can be carried out by several methods. What exactly?

Sensor setup methods

They are not very much. But the proposed spectrum of action is enough in order for each owner of the smartphone to choose the most efficient, fast and simple method of setting the sensor.

Most often, the process is carried out in the following ways:

• through third-party specialized programs;
• through. engineering menu;
• in service centers.

Engineering menu

Let's start with independent actions. How is the Android touchscreen calibration via the engineering menu? To do this, you need to stick to some action algorithm. Usually this method It turns out the fastest, but not always it is effective. Touchscreen Calibration Android via the engineering menu requires the following actions:

• Enable mobile device. It is necessary to wait for a full download operating system. If the gadget is already included, it is better to complete work with all previously active applications and games.
• Go to the device settings.
• Select the "Display" menu item in the list appeared.
• Examine the proposed operations. At the bottom of the list will be the inscription "Calibration of the G-sensor". You must click on this line.
• Put the smartphone on a flat surface. This is important for proper setting Devices.
• Click on the "Calibrate" button. Follow the instructions on the screen. A little wait.
• Reload the smartphone.

That's all. This android touchscreen calibration after the sensor is replaced or simply subject to each owner if necessary. mobile phone. As already mentioned, this method is not always effective. For example, if you do not put a device on a flat surface, then failures are possible when tuning the sensor. Then it is recommended to give preference to a different method.

Third-party applications

How is the Android touchscreen calibration? The program for setting the sensor is that it will help to solve the task. As already mentioned, third-party software is also often used to calibrate. This decision is not the safest, but extremely effective.

How can you configure the touchscreen on Android? For this will have to:

• Find and download the program to calibrate the touchscreen. Next, a list of verified and secure software will be given to implement ideas in life.
• Download the appropriate application to your mobile device.
• Install one or another program in which the Android touchscreen calibration will be performed.
• Close on the smartphone all active applications, programs and games. Run the software for calibration.
• Click on the "Start / Calibration" button. The inscriptions may vary depending on the application used. Before this is recommended, as in the last case, put the device on a flat surface.
• Wait for the completion of the process. It is recommended to restart the smartphone after the end of the sensor setting.

Quickly, simple, comfortable! This option is used by the gadget by many users.

Calibration programs

Now it is clear how the Android touchscreen calibration occurs. Many are interested in what programs can be trusted to configure the touch screen. Many suitable software. But best programs it could be considered:

• DISPLAY CALIBRATION;
• Touchscreenune.

Usually, the calibration applications are downloaded via Play Market. Only there you can find 100% secure applications to configure the touch screen. From now on, it is clear how the Android touchscreen calibration is performed after replacement or simply if necessary. To cope with this work will now be able to every person. Contact B. service centres This service is recommended in extreme cases.
