Android lives its own life what to do. The touchscreen (sensor) does not work well on an Android phone or tablet

Greetings to everyone and everything! I didn’t want to write the title of the article that way, but it’s very difficult to find another word other than “buggy”. It is very capacious (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, all 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 in this - everything has a logical explanation. Which? Now we will all know! But first, let's decide after what actions the screen of your iPhone or iPad can begin to live its own life, create chaos, full program and scare its owner.

There are not so many of these actions:

Firmware update.
Physical damage (fall, impact, moisture ingress).
Replacement or repair of the display (possible nuances).

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

Let's start with the general preparation of the device, which will help eliminate some of the standard points that cause the touchscreen to behave in such an incomprehensible way:

If there is a film or glass stuck to the device, remove it.
Wipe the screen thoroughly with a soft cloth. Do not use special wiping liquids, sometimes they can simply ruin the oleophobic coating.
In order to exclude software problem and bugs in iOS, do .

Yes, everything that is listed above is rather banal, but it can help. However, this is not all the actions that can be performed in order to get the display working.

And the first thing you should pay attention to is non-original power supplies and Lighting wires. Although, we will rather talk 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 encountered this and saw how a person’s phone was charging and at the same time periodically lit up, the screen unlocked, pressed by itself, characters were printed on the keyboard. Frankly, I was very surprised how iPhone yet did not call somewhere on your own!?

After a short conversation, it turned out that although this is annoying for a person, he simply does not want to buy the original wire (I rarely use it, and it will do!). The fact that the 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 iPhone display lives its own life and does not respond to pressing only during charging, with a high probability the charger is 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. There were just a huge number of them, but there is an explanation for this:

Many models are simply wildly popular, such as the iPhone 5S.
China will help everyone.

Here you have a large number of screens of varying degrees of quality. Moreover, they can be installed both during repairs and on “new” (actually restored it is not clear where) iPhones. And if you are unlucky, and the screen is set to the very “left”, then accidental clicks and other joys of life are provided.

By the way, a characteristic feature of this defect is that after locking / unlocking the device, everything returns to normal, but for a while, and then it starts to “fail” again. This can manifest itself both immediately after repair / replacement, and after iOS updates. How to proceed in this case? Option two:

Set normal display.
Try sticking a 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 to ensure that the iPhone or iPad display behaves correctly and does not live its own life. Genius move! The difference between a good screen and a bad one 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 is "buggy", most likely it's just not very good quality. Replacement required. There is also a more budget solution that helps many - film (glass) stickers. With the iPad, the situation is completely similar, only it's harder to glue :)

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

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

Conclusion three: the most severe malfunction in which the iPhone display is pressed by itself is a breakdown of the screen sensor controller. Compared to previous problems, it 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 the screen of your iPhone will be cured by an elementary replacement charger, wires, well, or in extreme cases, a sticker of a film or glass. And it will not come to a complex repair in the service center. 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 :)

P.S.S. And of course, if you have any questions or practical advice on how to defeat a "buggy" display - be sure to write in the comments!

e under Android control. 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 face the problem when phone either android 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.

For example, the device has problems with a 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 work of touch input (touchscreen) smartphone or android tablet is to blame software failure, which you can fix on your own.

Fixing a software bug:

Method 1. Pretty simple - go to "settings", find there « backup and reset" in which you choose full reset settings to delete 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 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 ov 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 controls system functions, corrects, and corrects everything possible mistakes settings and synchronization is small and easy to handle, free utility for Android devices. Download app from Google Play and watch it additional options in the description is possible . 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.)

In addition, it is worth cleaning the system with a NORMAL antivirus. Best of all, it copes with this task kaspersky antivirus , which you can download. Unlike the “multi-cleaner”, Kaspersky Lab’s software is paid, so if you don’t have the opportunity to install such protection, you can skip this step ...

Method 3.

Changing the device software, or, as it is also called "re firmware ".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 for repair of your tablet a or smartphone a.

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?

Every year, dozens of new smartphone models are released by manufacturers. Some as a distinctive feature can boast of their low cost, others high performance, others ergonomic design, the fourth is endowed with excellent energy-saving characteristics, a powerful battery and shock resistance. But none of these devices can be 100% protected from breakdowns of a different nature. One of these troubles is the spontaneous operation of the touchscreen, which, as a rule, is inherent in Chinese budget 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.

Incorrect operation of 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 under which the erroneous operation of the screen occurred, it is more or less likely to say which of the above failures caused this problem. So, in Chinese budget models (according to statistics, most often in Alcatel and Xiaomi), the incorrect functioning of the touchscreen occurs as a result of low-quality assembly of the device and a cheap resistive display, which is known to be vulnerable to the accumulation of static charge on its surface. Dropping a smartphone or pressing hard on its screen can also cause trouble with the touchscreen.

However, you should not despair. Before claiming that screen errors arose due to hardware damage, you should try to fix this problem software methods. Let's consider them in more detail.

How to eliminate the spontaneous operation of the sensor programmatically

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

Method 1: factory reset your smartphone

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

Method 2: Screen Calibration

Recalibration of the touchscreen may be needed not only in the event of a software failure, after which the sensor on the smartphone clicks by itself. After the fall mobile device from a height, getting it into the water, replacing the display, etc. calibration must be carried out without fail - this can help in most of the cases listed here. Let's consider two methods that allow us to carry out this procedure.

Screen calibration using standard tools built into the smartphone

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

Go to the "Settings" section of our device;
In the block "Display", "Screen" or "Accessibility" we find the item "Calibration" and click on it;
In the next window, it is suggested, as a rule, 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 app "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, primarily due to its ease of use, as well as the very high accuracy of determining the angle of inclination of the sensor.

So, to calibrate the screen using Touchscreen Calibration, you need:
Download the app from the Google Play link - https://play.google.com/store/apps/details?id=redpi.apps.touchscreencalibration ;
After installation, we launch 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 angle of the screen 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 so that the calibration is as accurate as possible.

At the end, you will be prompted to reboot the device 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 fix the sensor pressures, then the problem most likely lies in the hardware of your smartphone. There are several hardware reasons due to which the touchscreen may work spontaneously:

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

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