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 in the search "Screen Calibration", 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 engineering menu if it doesn’t fit, then watch the video instruction, it will definitely tell you the right direction!
The richness of options for using such devices leads to their gradual failure, and one of the most common failure options is sensor dysfunction on the phone, when the latter simply stops responding to pressing (or reacts extremely poorly). In this article, I will tell you what are the causes of such dysfunction, and what to do if the sensor on the phone does not work.
Understanding what to do when the touch screen stops working
Causes of phone sensor failure
Consider the most common reasons for the failure of the phone sensor. They may be as follows:
- Random malfunction of the device;
- There is a large amount of dirt and grease on the gadget screen;
- The protective film on the screen of the device does not adhere tightly to the screen (air bubbles between the screen and the film, dirt, etc. are visible);
- The machine has overheated due to various reasons, or has been subjected to a sudden change in temperature;
- Moisture got inside the phone, which led to the oxidation of contacts;
- The sensor is physically damaged due to impact;
- The sensor has moved or peeled off;
- SD card or SIM card is unstable;
- The operation of any applications led to the freezing of the device and the sensor of the mobile device;
- The phone's memory is full and the phone cannot properly handle the touch screen;
- The internal components of the phone (board, cable, etc.) are out of order;
- Installing incorrect phone firmware led to problems with the sensor.
If the sensor is not working...
The sensor on the phone does not respond what to do
To restore the normal functionality of your phone's sensor, do the following:
- Restart your gadget. Often this helps to effectively fix the problem with the phone's sensor;
- Wipe the screen of the gadget with a soft clean cloth (microfiber) moistened with an appropriate liquid for cleaning displays;
Wipe your phone screen with a soft cloth
*#7353# - for most Android phones, especially Samsung;
In the menu that appears, select, for example, "TSP Dot Mode", and by clicking in different areas of the screen, see which parts of the sensor are not interrogated, this can help fix the problem that the touchscreen does not work.
- If the device overheats, move it to a cool place and let it cool down;
- Gently tap a few times on each corner of the screen - this method has proven effective for many users;
- If your protective film is pasted incorrectly (air bubbles, dirt, etc. are visible under it), replace the protective film (contact a specialist for its correct installation on the phone);
If necessary, replace the protective film of the phone
Free legal advice:
In case of significant damage to the screen of the device, only its complete replacement will help.
Restoring the sensor through safe mode
To boot into safe mode, turn off the phone completely (including by removing the battery). Then long press the Power button to turn on the gadget. When the logo of Samsung, Nexus, LG, etc. appears on the screen, release the power button, and then hold down the Volume Down button. Press this button when your device boots up, and you will see the inscription “Safe mode” at the bottom left of the screen.
- Calibrate your device if the sensor has not recovered. To do this, you can use the appropriate applications, for example, "Touchscreen Calibration";
Use the program "Touchscreen Calibration" to calibrate your device
Choose "Wipe data/factory reset" to reset your phone to factory settings
Conclusion
If the sensor on your phone does not work for you, then I recommend using the tips I listed above. If it is impossible to identify the specific cause of the breakdown, I recommend that you contact your gadget in service center- it is quite possible that your device will need a complete replacement of the touch panel.

The touchscreen (sensor) does not work well on an Android phone or tablet. The touchscreen (sensor) works by itself, it works some time after pressing, it tupits, lags, does not work correctly. What to do and how to fix?
Many users are faced with a problem when an Android phone or tablet starts acting up. It seems that it didn’t fall anywhere and didn’t “water” with anything, but it doesn’t work the way it should.
Free legal advice:
For example, the device has problems with the touchscreen, i.e. the touch input (“sensor”) does not work correctly. The reason for this may be:
1st: Software failure - i.e. the problem is crash software
2nd: Hardware failure - i.e. the problem lies in the "hardware" (i.e. - replacement or restoration of spare parts of the gadget is required)
However, do not rush to get upset - in 90% of cases with problems in the operation of the touch input (touchscreen) of a smartphone or tablet based on Android, it is to blame software failure which you can fix on your own.
Fixing a software bug:
Free legal advice:
Method 1. Pretty simple - go to "settings", find there " backup and reset ”, in which you select a complete reset with the deletion of all data. Be careful, using this method often turns out to be effective, but it entails deleting all photos, contacts, passwords, music, games, videos and, in general, all information stored on your smartphone or tablet. Therefore, first save everything you need by connecting the gadget to your computer. If this method does not suit you, or if the problem persists after it, see Method 2.
Based on solving problems with communication and network reception of phones and tablets based on Android method implementation of additional software. Utilities that control all processes inside gadgets. Today, there are quite a few of them, however, the fewer functions an application contains, the more, as a rule, it is effective. Best of all, it controls the system functions, corrects, and fixes all possible settings and synchronization errors, a small, and easy-to-use, free utility for devices based on Android Multi Cleaner. You can download the application from Google Play and see its additional options in the description HERE. After installing the application, it remains only to launch it. Further, from you, in principle, nothing more is required. The application will take full control of the device functions. (By the way, among other things, the gadget will start charging 20% faster, and its performance will also increase significantly, which will affect the loading and operation speed of all applications, games, and the system as a whole. On average, after scanning, the system runs on 50% faster.)
Changing the device software, or, as it is also called "flashing". This method, as a rule, requires certain skills and is solved by contacting the Service Center. For the independent implementation of this task, you need to contact the manufacturer's website of your device, download the utilities necessary for the firmware and the firmware itself, and then reinstall it on your gadget.
If none of the methods brought results, unfortunately, you will have to contact the Service Center to repair your tablet or smartphone.

The sensor on the phone does not work: what to do
A touch screen device is functional and practical. Unfortunately, the reliability of such screens is low and the question of what to do if the sensor on the smartphone stops responding is very often asked on various forums.
Since the phone has no more control buttons, all functions of the device are lost in one second. Troubles usually begin after the mobile is dropped or moisture gets inside, or it may stop working by itself, as happens with Chinese phones.
Reasons for the inoperability of the touchscreen
There are various reasons that can lead to such a malfunction:
Free legal advice:
The phone memory is overloaded and the device does not have enough resources to process the clicks.
The sensor on the phone does not work on the video, what to do:
Display dirty
Over time, the sensor may become covered in fingerprints, or grease. This leads to a deterioration in the sensitivity of the touchscreen. It is necessary to carefully wipe the screen with a special liquid and a dry cloth.
Inappropriate temperature setting
A sudden change in temperature may cause the device to stop working.
Loose or damaged cable
It provides a touch-coated connection. This problem can be solved by yourself with a small screwdriver if the phone is out of warranty. If there is a warranty card, of course, go to a service salon.
Free legal advice:
Due to moisture in the phone
When liquid enters the gadget, oxidation occurs. Try drying your device with a hair dryer.
Contact oxidation
This problem is eliminated by careful cleaning.
Software failure
You need to reflash the device. To do this, you need to have software and a USB cable.
The video sensor does not respond:
How to reanimate the sensor at home
The very first thing to do is to restart the phone, while removing the battery and SIM card. Sometimes you need to reset your phone to factory settings. If a deep reboot did not help, then when performing further actions, you need to understand all the risks and responsibilities.
Free legal advice:
In some phones, to get to the buttons, you will need to disassemble the entire body of the device, and for this you need to study the sequence of disassembling the device. Without knowing this, there is a chance that the device will be damaged, and the repair cost will be much more expensive.
Armed with special tools, carefully remove the touch screen. After that, you need to carefully inspect the cables and connection connectors. The operation of all functions of the device depends on their integrity. If there is no damage, then simply disconnect the display from the board and connect it back.
Since the phone has already been disassembled, we gently wipe the contaminated contacts on the board with a cotton swab with alcohol and assemble the phone back.
In such a cunning way, it is easy to put it in place.
When all the screws are tightened and the assembly is completed, you can put in the battery and turn on the phone.
Free legal advice:
If, after all the manipulations, no changes have occurred, and the touchscreen still does not work, then replacing the touch glass will help you. What is extremely undesirable to do at home, and here you can’t do without a service center.
How to find a person by photo on the Internet using your phone or tablet, you can find out by reading this article.
You need to monitor the touch phone and handle it more carefully than with the push-button.
Do not drop it and prevent moisture from getting inside, and then you will encounter such problems less often.

Phone samsung s 7262, it was accidentally transferred to the screen, the sensor started to fail, when you enter words without touching the screen, it happens that you press the letters, you have to turn off and on the screen
Hello everyone, there were similar problems with the Samsung Gakaxy Tab 3, the tablet phone fell a lot and, in fact, the whole case was like after the bombing. Over time, the sensor began to fail, namely, when the processor overheated, the screen stopped responding, it worked, but did not respond to touch. I disassembled it at home, I myself, completely, checked the processor and didn’t understand shit, but after assembly everything worked fine. Yesterday, after an "accidental" hit on the screen, this problem reappeared. I tried to solve it by blowing the loop, blew it, connected it, worked for several hours, covered myself in the morning. As soon as I didn’t blow into it and didn’t pick this cable, it didn’t matter to him, I had to peel off the screen and get to the screen chip. As it turned out, the blow was straight into this very chip. Another cable was connected there, I removed the film, took out the cable, put it back in - it didn’t work. Well, I think that’s it, I’ll have to fork out, but I remembered that there was a video on YouTube where a dude poured current from a lighter on the screen so that some areas returned to working condition, I decided to try: it broke through the main cable, it didn’t go in, it broke through the chip cable, it didn’t go in, it blew the chip current, the sense returned. I say right away: this can be an ordinary luck, and in your case it will not help, especially for those who have a non-separable panel, but often breaking through some elements saves the life of the equipment. Do not repeat this on new phones, and even more so on those that have a guarantee, but for those who like to experiment and who don’t really need their device, go for it, maybe it can! All the best and cookies, maybe someone helped.

Slows down Android: causes and solutions
Every owner of a smartphone or tablet immediately after purchase is very happy with the speed at which his device works. All operations are performed quickly, responses to touch are timely and without glitches with pictures. But over time, everything changes and performance deteriorates. Why does Android slow down?
Main reasons
Among the reasons that Android slows down or freezes, there are several main ones:
- slowdown can cause a large number of simultaneously running applications, albeit in the background;
- due to a recent update, a smartphone that has not slowed down before may start to do so;
- any device can freeze even when it starts to run out of free space;
- a small amount of RAM can even cause the gadget to spontaneously reboot;
- sometimes the phone can fail due to problems with the touchscreen.
What to do if the phone began to slow down for one of the listed reasons?
Troubleshooting
Application cleanup
When the phone began to slow down a lot due to gluttonous applications and background processes, then to correct the situation you need to:
- hold down the menu button, a list of recently launched applications will open, select "Delete all";
- in the Application Manager, view the list of those running (opposite each, the operating time and the amount of RAM it occupies) and stop forcibly each unnecessary at the moment;
- in addition, you can remove live wallpapers and widgets, which also greatly affect the productivity of the device;
- applications that the owner of the gadget does not use should be deleted altogether in order to avoid running their processes in the background in advance.
Rollback update
Why does the device slow down after the update? The fact is that over time, any smartphone or tablet becomes obsolete, and each a new version Software or Android with its add-ons requires more and more powerful stuffing.
- Through recovery. First you need to download the required firmware version to your phone and save it on a memory card. Then enter Recovery (more often with a combination of the power buttons and the volume rocker down). Next, install the downloaded update and reboot the phone.
- Through a computer. To do this, you need to download the installation file from the official website of the manufacturer and use the software supplied with the phone (usually on a disk) to install it on a gadget connected to a PC.
After that, it is desirable to disable the function in the phone. automatic update system so that you do not have to repeat the procedure. It should also be remembered that after flashing from the phone, all data may be lost, therefore it is better to make a backup first.
Free up internal memory and storage space
When the device runs out RAM, it tries to make up for it at the expense of internal memory. If its volume is too small, the phone may refuse to perform any actions. In this regard, you need to periodically perform the following actions:
- clear the cache of the system and applications;
- resorting to special applications, clean the system itself (this will end background processes);
- synchronize media files on the "cloud" or with another drive and clean up from your device;
- do not forget to carry out the same actions with a flash drive, because. a small amount of free memory on it also affects the performance of the device.
Sometimes at the end of the RAM it is enough and just to reboot the phone.
Screen calibration
What to do if the sensor on the phone is buggy? In this case, you need to configure the problematic display to correctly execute commands after swinging your fingers or stylus. Otherwise it is called screen calibration.
Such a need arises more often after mechanical damage or contact with water. And to be sure that it is the sensor on Android that is the problem, you need to:
- remove the film;
- on the keyboard, try to enter any character.
If another number or letter pops up, the touchscreen will have to be calibrated. You can configure the sensor sensor using special programs(eg Touchscreen Repair), or manually. In the Play Market you can find a large number of necessary applications, and free ones.
Self-calibration is carried out as follows:
- in the phone settings, go to the "Display" tab;
- find the item, the name of which will be "calibration";
- put the phone on a flat surface and press calibrate (in some models, the phone will offer a target, in the center of which you need to hit at least 3 times);
- reboot the gadget and check the response again.
On the LG L90 smartphone, the calibration item was found in the "General" tab, the "Gestures" item.

You can visually see both methods of screen calibration in this video.

In this case, you will have to reflash your gadget with a return to the previous, workable version. You can do this in two ways:
- Through recovery. First you need to download the required firmware version to your phone and save it on a memory card. Then enter Recovery (more often with a combination of the power buttons and the volume rocker down). Next, install the downloaded update and reboot the phone.

When a device runs out of RAM, it tries to replenish it using internal memory. If its volume is too small, the phone may refuse to perform any actions. In this regard, you need to periodically perform the following actions:
- clear the cache of the system and applications;
- resorting to special applications, clean the system itself (this will end background processes);

- in the phone settings, go to the "Display" tab;
- find the item, the name of which will be "calibration";
- put the phone on a flat surface and press calibrate (in some models, the phone will offer a target, in the center of which you need to hit at least 3 times);
- reboot the gadget and check the response again.
When the phone or tablet starts to slow down - applications start more slowly, there are delays when flipping through screens or when switching between items in the menu - this starts to strain and even annoy. And if this happens at a time when you need everything at once, then you want to smash the phone against the wall.
Performance degradation is a problem that we face not only on phones. Personal computers and laptops also start to slow down after prolonged use, this is normal. The good news is that the speed of Android can be restored.
Think back to when you first bought your Android smartphone. He also slowed down and buggy when performing simple actions? If not, then we will try to return the former performance to your phone or tablet.
We clean Android from unnecessary applications
So, the first step you need to take is to review all your applications. Each installed application takes up space in the system and therefore negatively affects its performance. Feel free to delete app if you don't remember the last time you used it! After all, re-installing the application, if necessary, will take only a few minutes, and deleting unnecessary applications will speed up your Android device and possibly save your nervous system 🙂
We clean the smartphone or tablet from debris
The second step to cleaning up an Android smartphone or tablet is to clear the device of junk.
Photo and video
Go to the gallery and view media files, delete unnecessary photo and video files. In the gallery, before deleting, you can review all the files so that you do not accidentally delete what is really necessary.
Downloads
Go to the downloads, usually a whole bunch of unnecessary garbage is also collected there, because of which Android slows down. Look through the files in the downloads and delete what you don't need.
Cache
Go to settings and select the "memory" section. Here we are interested in the item "Cache" or "cached data". A cache is information from various applications preloaded into the device's memory, such as gallery thumbnails, splash screens, and application media files. This data in large volume can also slow down the device. Therefore, boldly click on this line and confirm the clearing of the cache.
In the “Memory” section there is also an “Other” or “Miscellaneous” item, you need to be careful about cleaning it, you can go into it, but if you are not sure whether to delete any of its items, then it’s better to leave everything as it is.
We clean the memory card of the Android device
We go further - a memory card. A lot of unnecessary files are also collected on the memory card during active long-term use. The system takes longer to scan them, which slows down your Android phone or tablet.
Cleaning the memory card is best done with a backup copy of the data. To do this, if the computer or laptop has a card reader, then turn off the Android device, then remove the memory card and insert it into the computer. We create a folder on the computer disk and copy all the contents of the microSD card of our Android device into it. After copying, check if everything was really copied, this can be done by comparing the size of the information on the SD card with the folder that contains the copy.
Next, insert the memory card into the Android device and turn it on. The following steps will to complete removal all data from the memory card. We go into the settings, the memory item, look for the line "Erase memory card" or "Erase SD card" and start cleaning.
What is Hard Reset
None of the above helped? Well, there is still the most radical, but at the same time the most effective remedy. You may have heard its names such as Wipe (wipe) hard reset (Hard Reset) full reset Android, general reset Android, factory reset Android. All these names reflect the essence of this decision - a complete reset and return Android to the state when the phone was turned on for the first time. All data that was on the Android phone or tablet will be irretrievably destroyed!
How to make a Hard Reset (read carefully)
As a result of an Android hard reset, all photos, videos, applications, accounts, contacts will be deleted, so before executing it, make a copy of the necessary data!
So, if, nevertheless, Android got it so that a full reset is the only way out, then we do the following: Go to the settings, go to the restore and reset item, select "general reset" or "factory settings", scroll down the screen, put a tick on the item " Clear internal storage” and click the “Reset phone settings” button.
Should I change my phone?
Even if after full reset Android phone slows down, then maybe it's just outdated and no longer meets your requirements, it's time to change it! 🙂
To evaluate the performance of the phone, there are special applications, for example. Install and run this application and test your Android device, if your faithful friend scores less than 6000-7000 points in the test, then you should seriously think about a new device.
When choosing a new device, it is desirable that it score at least 15,000-20,000 points in Antutu, this is a necessary minimum for comfortable work and running most games. But that's a completely different story.
I hope these tips will help speed up your Android and save readers a nervous system 🙂
P.S. By the way, while writing this post, the Acer Extenza 5235 laptop was almost damaged due to tomoses 👿
Push-button phones have been replaced by touch devices. What has changed after this technology has firmly entered our lives? Almost everything that is in any way related to the functioning of the device. That is why the situation in which the sensor stops working requires immediate resolution. And in many cases, a person has almost every chance to restore his device. We'll talk about this in more detail later.
Why did the sensor stop working?
There are quite a few reasons why the sensor on the phone does not work (what to do is described below). Given the manufacturability of the touchscreen, as a rule, most often this control is rather fragile and finicky. Its performance is most dependent on weather conditions, damage, and liquid ingress.
If there was a software failure or a spontaneous failure of the system to work, then there may be problems with the operation of the sensor. These shortcomings, in principle, are conditional, they can be easily avoided. We can seriously say that a person is the most important factor in the performance of a mobile device. It is the actions of the owner that will determine how long the device will be in operation and why the sensor on the phone does not work.
Common Touch Screen Problems
Often, breakdowns are formed due to mechanical damage. If the phone is dropped or deformed, the device will not work properly as a result. Due to impacts or other mechanical influences, various consequences can occur. As a rule, they can be ordinary lid chips at best, or a cracked display at worst. If the deformation of the case does not affect the operation of the gadget in most cases, then the screen will need to be replaced. If the sensor stops working, then you need to pay attention to the components of the mobile device. If there is a body part slightly moving away from the display and you can notice a gap, then you should immediately carry the phone for repair.
Sometimes a smartphone may stop working if liquid gets into it. It is completely incomprehensible to many how water manages to get on the board, but this is a common problem.
Self-Rehabilitation
If the sensor on the phone does not work, what to do is not clear, then you must first go to the device settings. There you need to calibrate the touchscreen. Often this feature can be found in the main settings. These actions can be carried out if the screen is completely in order, the case is intact, there are no signs of deformation or oxidation. If the sensor has a perfectly smooth surface, then it is likely that the touchscreen has simply turned off.
If the forecasts are not entirely optimistic, the sensor on the phone still does not work, what should I do? It is better to start looking for a solution to your problem right away. In order to perform the following actions, you must have certain skills.
Oxide elimination
In order to eliminate the oxide, it is necessary to use a special tool - this is a Phillips and flat screwdriver. An unnecessary plastic card will also work. You should take alcohol, a toothbrush, an eraser and napkins. Before you disassemble your device, you need to watch the video, which describes how to do it. To do this, simply type in the search engine the model of your phone and look at the reviews on it.
Care must be taken when separating the body parts. There is a risk that a person may fly a cable, break wires or break any parts. In order not to get lost with the screws, you need to draw a diagram of the phone and arrange the screws according to the drawing. All accessible places that liquid can get into should be wiped with alcohol, then with an eraser and then blotted with a napkin.
In order to eliminate corrosion of the board, you need to use a toothbrush. Often this is the reason that the phone sensor has failed. Where there is a connection of loops, especially when it comes to the touch screen connector, it is necessary to treat with alcohol and remove plaque with an eraser. As a result, the surface will be dry and clean.
If there was a peeling or displacement of the screen, then this is probably the problem. Often in such cases, the phone sensor fails. In order to put the screen in place, you must use a hair dryer. You can peel off the touchscreen from the display by simply heating it. The glue will dry, and then it will be easy to move the sensor to the right place.
The device must be assembled carefully and carefully, installation must be sequential. Don't forget to screw in the screws. It is also necessary to put protective cases back on the microcircuits.
Other ways: how to fix the problem
There are many other reasons why a sensor can fail, so human actions will directly depend on the failure. Sometimes you can solve this problem yourself, remembering that repairing touchscreen phones is an expensive service. For example, if the sensor does not work due to surface contamination and does not respond to touch, then it is necessary to wipe the screen with a liquid. You should also use a soft cloth. This is necessary if the question arises of what to do - the sensor on the phone does not work.
If the protective film was installed incorrectly and now the lower part of the sensor on the phone does not work, it is necessary to replace this coating by cleaning the screen from dirt. Often dust and dirt gets under the film. This is what makes it difficult to work with the sensor.
In other cases, a software glitch may be the cause. Solving such a problem is easy by resetting the settings or flashing the device. In the most urgent cases, contact the service center. We'll talk about this below.
If the sensor on the phone does not work for no apparent reason
If the sensor stopped working for unknown reasons, then it is better to contact the service center and carry out a complete diagnosis of the phone. This is the only way to find out the true cause of the breakdown and eliminate it without harm to yourself and the extra money spent. If the phone is still under warranty, then you can easily replace the sensor or solve the problem itself. As a rule, experts answer the question of why the sensor on the phone does not work quite quickly. This method is the most efficient. If a person does not want to harm his phone, it is best to immediately contact the service center as soon as a breakdown occurs. You should not, if there is no self-confidence, try to solve this problem on your own.
Results
Summing up, it must be said that the phone should be treated with the utmost care. Replacing a sensor on a phone is quite a complicated process and also expensive. Therefore, it is best to provide your device with the most ideal working conditions. No need to throw it or treat it carelessly. Be sure to periodically wipe the screen, change the protective film, only then you can really achieve excellent and long-term operation of the touch screen. If the gadget is under warranty, then replacing the sensor on the phone will be a free service.
