e under Android... The touchscreen (sensor) works by itself, works after a while after pressing, dulls, lags, does not work correctly. What to do and how to fix it?

Many users face a problem when phone or tablet on Android base begins to be capricious. It seems that he did not fall anywhere and did not "watered" with anything, but it does not work as it should.

For example, the device has problems with a touchscreen, that is, the touch input ("sensor") does not work correctly... This may be due to:

1st: Software glitch- i.e. the problem is crashing software

2nd: Hardware failure - i.e. the problem lies in the "hardware" (that is, it requires replacement or restoration of spare parts for the gadget)

However, do not rush to get upset - in 90% of cases with problems in the operation of touch input (touchscreen) smartphone or Android tablet is to blame software glitch, which you can easily fix on your own.

Fixing a software glitch:

Method 1. Quite simple - go to "settings" find there « backup and reset " where you choose full reset settings with the deletion of all data. Be careful, the use of this method is often effective, but it entails the removal of all photos, contacts, passwords, music, games, videos and, in general, all information stored on your smartphone e or tablet e. 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.

Method 2.

Based on solving touchscreen problems phone s and tablets based on Android by introducing 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 controls the functions of the system, corrects, and corrects everything possible mistakes settings and synchronization is small and easy to use, free utility for Android devices. Download app from Google play and you can see its additional options in the description. After installing the application, all that remains is to launch it. Further, from you, in principle, nothing else is required. The application will completely take over the control of the device's functions. (By the way, among other things, the gadget will start charging 20% faster, and its performance will also significantly increase, which will affect the loading and operation speed of all applications, games, and the system as a whole. On average, after scanning, the system works on 50% faster.)

In addition, it is worth cleaning the system with NORMAL antivirus. Best of all, it copes with this task Kaspersky antivirus , which you can download. Unlike the "multi-cleaner", the software of "Kaspersky Lab" is paid, therefore, if you do not have the opportunity to install such protection, you can skip this step ...

Method 3.

Change of device software, or, as it is also called "Per firmware ".This method, as a rule, requires certain skills and is solved by contacting the Service Center. To independently carry out this task, you need to contact the manufacturer's website for your device, download the utilities and the firmware itself necessary for the firmware, and then reinstall it on your gadget.

If none of the methods brought results, unfortunately, you will have to contact the Service Center for repair of your tablet a or smartphone a.

The touchscreen (sensor) does not work well in a phone or tablet running Android. The touchscreen (sensor) works by itself, works some time after pressing, dulls, lags, does not work correctly. What to do and how to fix it?

Dozens of new smartphone models are released by manufacturers every year. Some in quality distinctive feature can boast of their low cost, others have high performance, others are ergonomic design, the fourth are endowed with excellent energy-saving characteristics, powerful battery and impact resistance. But none of these devices can be 100% protected from breakdowns of various kinds. One of these troubles is the spontaneous operation of the touchscreen, which is usually inherent in Chinese budget models of smartphones. In view of what the sensor on the phone is pressed by itself and how to deal with this problem, you will learn from the article.

Wrong work the touchscreen is not the most pleasant phenomenon, but the problem is fixable

What are the reasons for the spontaneous operation of the touchscreen

Conventionally, the reasons that the sensor itself is pressed can be divided into two categories:

Software failure - occurs due to errors in the software (software) of the smartphone;
Hardware failure - errors associated with damage to the component parts of the device.

Depending on the model of your smartphone and the circumstances of the erroneous operation of the screen, it is more or less likely to assert due to which of the above failures this problem arose. So, in Chinese budget models(according to statistics, most often in Alcatel and Xiaomi) the malfunctioning of the touchscreen occurs as a result of poor assembly of the device and a cheap resistive display, which, as you know, is vulnerable to the accumulation of static charge on its surface. The fall of the smartphone or strong pressure on its screen can also cause trouble with the touchscreen.

However, you should not despair. Before claiming that errors in the functioning of the screen occurred due to damage to the hardware, you should try to eliminate this problem programmatic methods... Let's consider them in more detail.

How to eliminate spontaneous sensor triggering programmatically

So, let's consider several ways to solve this problem on our own.

Method 1: reset your smartphone to factory settings

Depending on the smartphone model, the restoration of the “default” operating parameters is performed in a certain section of the settings. However, the path to them is the same for most devices, only the names of these blocks differ. Therefore, we will consider how to reset the settings to factory settings, for example Philips smartphone S326.

Method 2: calibrating the screen

Re-calibrating the touchscreen may be necessary not only in the event of a software failure, after which the sensor on the smartphone itself clicks. After the fall mobile device from a height, getting into water, replacing the display, etc. calibration must be performed without fail - this can help in most of the cases listed here. Consider two methods that allow you to carry out this procedure.

Screen calibration by standard means built into the smartphone

In those models of devices that have in the standard functionality the ability to determine the angle of inclination of the touchscreen, you can calibrate it without using special utilities. For this:

Go to the "Settings" section of our device;
In the block "Display", "Screen" or " Special abilities"Find the item" Calibration "and click on it;
In the next window, as a rule, you are asked to put the phone on a flat surface and start the calibration procedure, then your device will automatically adjust the optimal touch angle and complete it.

Using the dedicated application "Touchsreen Calibration"

This method is suitable for those whose smartphone models do not have built-in screen calibration tools. The application compares favorably with similar ones, first of all, due to its ease of use, as well as very high accuracy in determining the angle of inclination of the sensor.

So, to calibrate the screen using Touchscreen Calibration, you need:
Download the application from the link on Google Play - https://play.google.com/store/apps/details?id=redpi.apps.touchscreencalibration;
After installation, run the program, in the start window we see the inscription "Calibrate", framed in a blue background, you need to click on it;

Click on "Calibrate" to start the touchscreen calibration process

The calibration procedure begins, during which it will be proposed to adjust the screen tilt angle in six different touch modes, we go through each of them;

Do not forget that the smartphone must be on a flat surface all this time in order for the calibration to be as accurate as possible.

When finished, you will be prompted to restart the device in order for the changes to take effect.

Here we click "Ok" and reboot the device in order for the changes to take effect

Conclusion

If the above methods did not help you to fix the pressing of the sensor, then the problem most likely lies in the hardware of your smartphone. There are several hardware reasons why the touchscreen can spontaneously work:

Resistive display - given view screens differ from capacitive ones in that they are a layer of glass on which a flexible membrane is applied, as a result, such a touchscreen wears out quickly;
Poor quality double-sided tape - Chinese manufacturers, and some service centers that repair displays by replacing it, like to save on double-sided tape, with which the screen is fixed inside the case. As a result, the touchscreen does not work properly.

For the above reasons, it is better to entrust the case to a specialist than to try to repair the screen yourself. If you still want to cope on your own, I recommend viewing these touchscreen repair guides:

The phone randomly began to press itself at the top of the screen. I removed the film, everything went, pasted another one, it seemed to work again, then again, the same, then the upper part of the screen about 1 cm stopped responding to touch. I disassembled and found out if you do not lean the sensor against the screen, then it does not press itself. Tell me how to solve the problem, can anyone have a similar or similar situation?

Users on iPhone, iPad and iPod are offended by the fact that the touchscreen itself is pressed on the screen and buttons, and after updating to iOS Beta, the touch stopped working. Today we will find out why the iРhone sensor hangs and is pressed by itself, and how to fix this nuisance for iPhone 5/6/7.

How to fix the problem - the sensor is pressed by itself

Using iTunes, the first thing to do is connect your iPhone to it. And should open home page control your iPhone, iPad. You can see on the top plate with information "Restore" by clicking it. And iTunes automatically updates the device to latest version... After rebooting the iPhone, the screen will stop working by itself.

If all does not help, then you need to contact the service center and replace it with a new display. And I would like to receive useful tips, do not hesitate, write to us!

Greetings to everyone and everything! I didn’t want to write the title of the article that way, but it’s very hard to find a word other than “buggy”. Very succinctly (the mighty Russian language is rich and beautiful!) It describes everything possible problems with a screen that lives on its own - keyboard buttons are pressed, desktops are scrolled, applications are launched, and all this without your knowledge. And the display itself does not respond to pressing!

It would seem that the situation is fantastic and somewhere even mystical, but ... in fact, there is nothing strange about it - everything has a logical explanation. Which? We'll find out now! But first, let's decide after what actions the screen of your iPhone or iPad can begin to live its own life, create chaos, limitlessness full program and scare its owner.

There are not so many of these actions:

Updating the firmware.
Physical damage (fall, shock, moisture).
Display replacement or repair (nuances are possible).

That's all. Although no, there is another option - none of the above happened, and the screen suddenly began to "glitch".

Let's start with the general preparation of the device, which will help eliminate some of the standard moments due to which the touchscreen behaves in such an incomprehensible way:

If there is film or glass adhered to the device, remove them.
Wipe the screen thoroughly with a soft cloth. Do not use special cleaning fluids, sometimes they can just ruin the oleophobic coating.
In order to exclude software problem and bugs in iOS, do.

Yes, everything listed above is quite commonplace, but it can help. However, these are far from all the actions that can be performed in order to adjust the operation of the display.

And the first thing worth paying attention to are non-original power supplies and Lighting wires. Although, rather, it will still be about wires (the adapter itself, as a rule, does not greatly affect the operation of the device). Here they are - yes, they can spoil the nerves.

Once I myself ran into this and saw how a person's phone was charged and at the same time periodically lit up, the screen was unlocked, pressed by itself, characters were typed on the keyboard. To be honest, I was very surprised how iPhone yet didn't call somewhere on your own !?

After a short conversation, it turned out that although this annoys a person, he simply does not want to buy an original wire (I rarely use it, and it will do!). The fact that spontaneous pressing of the display is not the worst thing that can happen, and the battery will definitely have to be changed soon, he was not interested.

Conclusion one: if the iPhone display lives its own life and does not respond to pressing only during charging, the charger is most likely to blame. Change and use only certified accessories.

If everything is ok with the charger, then it is worth moving on to the next reason - these are low-quality display modules. It became easy great amount, but there is an explanation for this:

Many models are just wildly popular, for example, the iPhone 5S.
China will help everyone.

So much for you a large number of screens of varying degrees of quality. Moreover, they can be installed both during the repair and on "new" (in fact, restored, it is not clear where) iPhone. And if you are unlucky, and the screen is set completely "left", then accidental clicks and other joys of life are provided.

By the way, a characteristic feature of this defect is that after blocking / unlocking the device, everything returns to normal, but for a while, and then starts to "glitch" again. This can manifest itself both immediately after repair / replacement, and after iOS updates... What to do in this case? There are two options:

Install a normal display.
Try to glue film or glass.

The most interesting thing is that some workshops, knowing the quality of the display they install, when replacing the module, "as a gift" stick a sticker on the screen. Often this is done just so that the iPhone or iPad display behaves correctly and does not live its own life. Brilliant move! The difference between a good screen and a bad screen is big, and the price of film is small. And everyone is happy: the client thinks that the service is good - he even glued the film, and the workshop itself won in money.

Conclusion two: if the iPhone display "glitches", most likely it is just not very good quality... Replacement required. There is also a more budgetary solution that helps many - a film (glass) sticker. With the iPad, the situation is completely similar, only it is harder to glue :)

There is another reason the touchscreen can behave strangely. But here it would be more correct to say that it will not handle pressing at all, and not “just” work in the wrong place.

Perhaps, it comes about the display sensor controller and it's very sad. It can be damaged in the event of a fall, shock, moisture penetration into the gadget and absence. Only a few service centers have the skill of re-soldering it (the procedure is done in order not to change the entire system board entirely). Well, it also costs money, respectively - of course, cheaper than a complete replacement of the board, but still ...

Conclusion three: the most serious malfunction in which the iPhone display is pressed by itself is a breakdown of the screen sensor controller. Compared to previous problems, this is rare and much harder to fix.

Here is such an unpleasant conclusion at the end of the article ...

However, I really hope that all the "glitches" of your iPhone screen will be cured by an elementary replacement. charger, wires, or in extreme cases, a sticker of film or glass. And before a complex repair in service center it won't work. Let it be so!

P.S. And to increase the chances of a successful outcome - put "like" and click on the buttons social networks, + 50% luck guaranteed :)
