A program to improve the performance of the lumium smartphone sensor. Calibrating the touchscreen on android

(Software for calibrating the touch screen). If your screen on a mobile device sometimes does not work well, then the Touchscreen Repair program can cope with this problem. Over time, with active use, the touch screen of absolutely any mobile gadget deteriorates. You may notice sensory lags, poor response or no response at all. Touchscreen Repair analyzes the response time of the touchscreen and makes it shorter, thus restoring your screen to functionality. The program takes 4 data values from 4 parts of the screen. The use of three parts allows for greater precision. Based on this data, Touchscreen Repair calculates a shorter response time and applies it to the touchscreen from the software side.

Peculiarities:

option to repair the touch screen, eliminate lags, increase sensitivity;
the process of typing on the virtual keyboard becomes simpler and easier;
makes the response time of the touch screen less;
fast and easy work process;
light weight of the application due to the lack of unnecessary graphics.

Over time, the touch screen of the device 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 can be done regularly to prevent screen response problems. 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 one.

Let's analyze the following calibration methods:

With the tool built into the system.
Through the Android engineering menu.
Using several third-party applications.

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

To use this function and configure the screen with it, you need:

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

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

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

If the function is present, then we launch it. A test will open, which consists in sequential clicking on certain areas. However, the test can be anything.

Engineering menu

Screen calibration on Android can be done through the engineering menu. It is a dedicated environment in which you can test all device components 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. The combinations will be different for different devices. 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 - * # * # 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:

Open the application through which calls are made.

Using the keyboard, type in the combination of characters that is suitable for your device (we will consider it using the example of a Xiaomi smartphone on Android 1.2).

Go to the section "Single Item Test", "Hardware Test" or another similar tab designed for testing.

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

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

On some devices, you don't have to do any additional actions - just go to the sensor calibration section, click on "Clear calibration", and then on "Do calibration". All actions will be performed automatically.

You need to reboot the device for the changes to take effect.

Third Party Applications

Perhaps the manufacturer has not built in your device the function to calibrate 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.

These apps work on any device, regardless of screen type, model and brand. Let's take a look at the best ones.

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

To correctly 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):

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

We tap on the search line and write the query "touchscreen calibration". We move on to the first result.

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 listen, you need to:

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

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

Click once in the area on the point indicated on the screen. Wait until the program displays the accuracy of pressing in percent and switches to the next step.

Tap the point twice.

Press the point and hold for 2 seconds.

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

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

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

As a result, the program will display a notification that the calibration has been successfully completed and the device needs to be rebooted. All that remains is to check if the sensor is "slowing down" and whether the problem has been fixed.

We draw your attention to the fact that after each action, the utility should display the result, which is presented in the screenshot of the phone's desktop below.

With Touchscreen Calibration, you can calibrate the sensor in just 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 the phone, we perform the following set of actions:

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

Find the item "Display Calibration" and tap on it. Verification will be carried out.

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

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

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

Service center

By no means always inaccurate or accidental clicks occur due to failures in screen calibration - some problems cannot be solved by the software setting. Usually, using the methods we have described, only minor deviations from the ideal are corrected.

If the screen of a tablet or smartphone itself presses 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, the device should be carried to the SC, since mechanical damage can become the cause of serious violations in the sensor's response.

Video instruction

We attach a detailed video instruction on using all the methods for calibrating the Android display described in the article.

Conclusion

We recommend that you calibrate every two to three months to avoid any abnormal sensor performance. In addition, this procedure must be performed after installing a protective film and when moisture gets into a smartphone or tablet, as well as after repairing the screen.

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

Owners of mobile devices running on the Android operating system often face the problem of incorrect touchscreen response to touch. Calibrating the android screen usually helps to fix such problems. Without periodic implementation of this procedure, the smartphone begins to respond to the commands entered with a significant delay, confuses the touch buttons.

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

If the device starts to "glitch" after such situations, touching certain points of the touchscreen launches 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 to the typed data.

The 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.

Calibration methods are few, but they are sufficient to carry out this procedure quickly and without much difficulty. To normalize the operation of a downed touch sensor, you can:

It should be noted that in most android devices from manufacturers Lenovo, Nokia, Samsung and others, this process will practically not differ in any way. The only problem most often faced by owners of gadgets with resistive screens, 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-technology for manufacturing displays is practically not used today, but is found only in budget and outdated models. Devices with capacitive screens are considered to be of better quality and more reliable.

Using settings

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

Turn on the gadget and wait until the OS is fully loaded.
Quit all games and other active applications.
Open "Settings", where click on the sub-item "Display".
Select "G-sensor calibration" from the offered list of operations.
Place the device on a flat surface, which is necessary for its correct configuration, and press the "Calibrate" button.
Follow the instructions on the display.
After a short break, restart the device and check its functions.

This setting can be done on any touchscreen smartphone. But it is important to remember that this method does not always allow you to achieve the desired result. For example, in the absence of an opportunity to lay the phone on a flat surface, the sensor intermittently malfunctions.

Engineering menu

To calibrate the Android touchscreen after replacing the display or simply when the need arises, you can also use a special menu. It allows you to make many of the tinctures that are not available in the usual 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 touchscreen using dedicated 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 a good result. The most popular applications are Power Bubble, TouchScreen Calibration, Clinometr and many more.

Power bubble

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

To work with the application, it is enough to select the desired screen orientation or set the automatic mode at the initial start-up. After that, they begin to set up the wheelbarrow, for which the gadget is placed on a flat surface and the calibration button is pressed. The screen should display the words Calibration and Wait. Further, a zero degree value will be formed, which will indicate that the program is ready for operation.

Clinometr and others

Very high quality screen setting application - tscalibration. It is equipped with a large number of options to make the most accurate calibration possible. To use the 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 actions, after which a message will appear on the display stating that the setting was successful.

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

Do I need to calibrate the display

First you need to diagnose the smartphone for sensor response errors. To do this, just turn on the keyboard and press different keys. If the screen shows exactly the symbol that you called, then calibration is not required. However, if the response is wrong, you need to solve the problem using any of the methods described below.

Calibration required:

Every 1-2 months using a smartphone;
When applying protective glass;
When buying a new phone or device from your hands;
After falling or getting wet;
After replacing the screen or touchscreen;
After removing or sticking the protective screen film.

Instructions for setting up the sensor on android phones:

We carry out diagnostics in the way described above.
Go to the "Settings" menu and look for the "Phone settings" item, in which you need to click on the "Screen calibration" sub-item. Sometimes the calibration menu can be found in the "Display" section.
You will see a small cross on the screen with a small red dot in the center. It is necessary to press it as accurately as possible several times, and then save the parameters so that the screen responds correctly to touches.
We check the result and, if necessary, repeat the procedure.

Also, if your phone does not provide a function for adjusting the sensor in the system menu (and this, do not be surprised, happens on some smartphones), you can download a special application. This function is performed in them in the same way as described above. Some applications have additional functions that allow you to customize the display in the most accurate way.

Calibration of the touch screen on mobile devices with the Android operating system may be required if the touch screen does not correctly recognize touches. Depending on the manufacturer of the smartphone, the system may have various built-in calibration utilities. You can also use third-party apps to customize your Android sensor.

Calibrating the screen on Android through the built-in utility

The standard methods for calibrating the display on smartphones from different manufacturers differ. As a rule, the setting is performed through the engineering or service menu. To call it, you need to enter a special code in the Dialer application (a standard program for making calls on Android). The code can consist of numbers, symbols "*" and "#". The specific combination for a specific brand of phones can be found in the documentation for the device or on the manufacturer's official website.

Advice! Use the “Touch” or “Calibration” menu item to change the touchscreen parameters. The exact address can be found in the instructions for the Android smartphone.

If basic Android tools are lacking or ineffective, use third-party software. One of the most popular options for such applications: Touchscreen Calibration. The utility is free and available for download through the "Google Play Market". It can help improve the accuracy of touch recognition and gesture recognition.

After installation, you will be prompted to take several steps to calibrate the screen on Android:

Touch;
Double touch;
Long press;
Scrolling;
Approximation;
Withdrawal.

Important! If the Android smartphone does not recognize all gestures, there may be problems with the touchscreen. Restart your device, and then test the screen movements in other applications.

SGS Touchscreen Booster

Unlike the previous utility, setting the sensor parameters via the SGS Touchscreen Booster is performed in manual mode. Using the sliders, you can change the values of the five main touchscreen settings:

Sensitivity;
Duration for registering a press;
Minimal movement;
Motion filter;
The maximum number of simultaneous clicks.

The default value is indicated in brackets after the parameter name. If necessary, you can return to the default display settings by specifying this number. You can also use the "Defaults" button in the lower right corner to set the default Android display settings.

The program has a set of predefined templates. You can choose the optimal variant of sensor operation from the “Presets” drop-down list. To apply the settings every time you boot Android, check the "Start service on boot" item.
