When receiving notifications by default after blocking, the screen of an android or iPhone phone constantly lights up.

If the screen on your nokia, samsung, xiaomi and so on lights up by itself, for no particular reason, this may indicate problems with the operating system or hardware.

Some applications may be the reason for this. Below you will find tips on how to deal with this.

In general, this is a rather rare phenomenon, but nevertheless there are three reasons for this. More details below.

Yes, I almost forgot, there is a program that can restore the health of any phone. Get to know her and

The phone screen lights up by itself - a problem with the operating system

The operating system on your phone controls various device features, including the notification light and screen.

Errors in operating system or user-generated problems, which usually arise from previously rooted rights, may cause the screen to turn on spontaneously.

After getting root, this was the case on one of my smartphones from the manufacturer samsung.

In this case, you can restore the factory settings of the phone. About this, how to reset your phone, I already wrote some time ago -

The phone screen lights up by itself - an application problem

As a result, the display of the phone may light up. To solve the problem, go to the smartphone settings and on the applications tab turn off the notifications of individual programs.

The phone screen lights up by itself - a hardware problem

On some phones, the problem with uncontrolled screen backlight appears due to pollution accumulated in the equipment.

For example, dust and dirt that accumulates in the charging port can interfere with the power supply process, causing the notification light to turn on.

This, in turn, leads to spontaneous backlighting of the screen - it lights up as if by itself.

To solve this problem, thoroughly clean all the ports of your smartphone with compressed air or a toothbrush.

Sometimes the problem of spontaneous screen backlighting is the result of a mechanical defect.

Therefore, if you try to fix the problem yourself and you fail, go to the service to specialists. Good luck.

Every year, dozens of new smartphone models are released by manufacturers. some as distinguishing feature can boast of their cheapness, others of high performance, others of ergonomic design, the fourth are 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

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 arguing that screen errors arose due to hardware damage, you should try to fix this problem using 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, let's consider how to perform a factory reset, using the Philips S326 smartphone as an example.

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 a mobile device falls from a height, falls into water, replaces 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:

1. Go to the "Settings" section of our device;
2. In the block "Display", "Screen" or "Accessibility" we find the item "Calibration" and click on it;
3. 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.

1. So, to calibrate the screen using Touchscreen Calibration, you need:
2. Download the app from the Google Play link - https://play.google.com/store/apps/details?id=redpi.apps.touchscreencalibration ;
3. 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 type 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:

Spontaneous turning on of the display in HTC smartphones is a fairly common situation. Users see this very often. The display may light up even if there is no user action.

It's no secret that the spontaneous operation of the display affects the autonomy of the phone, as the screen is one of the most powerful consumers of battery power.

How to fix the random display on HTC

Spontaneous screen illumination in the vast majority of cases is not a problem as such. This is a normal operation of the HTC smartphone due to the activity of some applications or services. Spontaneous activation can be:

1. When applications are active, even in the background. To fix it, you need to go to the settings and remove the icon from the item "Background mode", "Active indication", "Display settings" etc. It all depends on the specific application that causes the screen to turn on.
2. When some screensavers are running. Such programs may well spontaneously turn on the display. Eliminated by changing their settings.
3. With incoming messages from a cellular operator. Eliminated by disabling additional services provided by the cellular operator (via the operator's menu or through communication with the contact center).

Greetings! Spontaneously turning on the display on the phone - this problem can bring anyone to hysteria. It would seem that, simple thing- well, it lights up by itself, so what? However ... how many inconveniences at once! The main ones include very fast iPhone charging. The smartphone does not hold a charge too much anyway (see approximate data and compare with your indicators), and then there is the main consumer of energy - the display, which turns on when it wants to. Horror!

It is immediately worth noting that there are three main reasons for such a problem - it can be the fault of the software, the telecom operator, or an “iron” breakdown. Yes, it's all so simple. But this is only at first glance. And on the second...

In general, let's quickly find out - how to deal with all this disgrace? Let's go!

Raise to Wake and other software "features"

In iOS 10 for iPhone 6S, 6S Plus and SE, the Raise to Wake feature began to work. When it is activated, at the moment when you pick up the device (lift it from any surface), the screen lights up on its own. This is done for the convenience of unlocking - you just have to put your finger on the Touch ID sensor.

So if you complain that the screen on the iPhone turns on by itself only at the moment when you pick it up, this is the action of this option.

In some cases, the Raise to Wake option may not work perfectly, try not to lift it from the surface, but simply shake the locked iPhone - the screen backlight will light up. A similar situation can occur when the phone is shaking a lot, for example, in a pocket.

Therefore, if this is relevant for your phone model, turn off this function and check if the automatic backlighting has disappeared? For this:

Done? Have you checked? Nothing has changed and the backlight can still flash on the screen at any time, despite the fact that the phone is locked? There are several other software features that can cause the display to behave in this way. Here's what you can do:

• Check apps and games installed on iPhone. Perhaps this is just a "bug" of some separate program. For example, a notification from her should come - the screen lights up, but nothing comes.
• Jailbreak. Check all tweaks that have been installed or updated recently. Delete one by one starting from the most recent. But in general, it is better to remove the jailbreak itself.
• , but (important!) do not restore from a backup. See if the screen stops flashing on its own on a completely “clean” device.

But all this may be meaningless, because there is a chance that the "root of evil" is in a completely different place - from which you do not expect such a "setup" at all ... a SIM card.

The screen on the iPhone turns on by itself - is the SIM card to blame!?

In fact - easily. To be more precise, this is not the fault of the SIM card itself, but of the entertainment services connected to it. This is especially true if the SIM card is new - just bought or replaced. Moreover, each operator has one such option, which at some intervals shows various information on the display - thereby activating it for several tens of seconds without your knowledge.

But such information messages do not always appear. In some cases, the iPhone will simply turn on the screen, but there will be no text on it.

Here are the options you should pay attention to first of all:

• Beeline - "Chameleon".
• MTS - MTS News.
• Megaphone - "Kaleidoscope".
• Tele2 - "Tele2 theme".

It is these services that cause the display of your phone or tablet to turn on periodically. Yes, for the iPad it will work on par with the iPhone. For example, on my iPad with a new MTS SIM card, a black screen constantly lit up with the text "The SIM card played a sound."

Disconnected "MTS news" and everything went away.

Be sure to turn off these services (you can do this either through the operator or by special commands) - the “calmed down” screen backlight and battery will thank you.

The display lights up by itself - problems with the "pieces of iron" inside the iPhone

Perhaps the saddest option. And you have to be sad because you can’t identify a single reason. This is not to say - the locked display is activated from time to time only because of the battery.

There can be a lot of options and the battery is far from the only one of them:

• In the event that this happens during charging, it is worth checking the power supply, cable and wire connector on the iPhone. You need to try to replace the Lighting adapter and cable, but carefully clean the connector - it may have oxidized or dust has clogged in there. You can clean it with a brush or a toothpick (no metal objects!).
• If, in addition to the fact that the screen lights up by itself when it is locked, the device (when it is completely turned off) also turns on on its own, then you should look towards the upper cable with the power button.
• You also need to pay attention to the bottom connector and the Home button (especially if moisture got there).
• And of course, low-quality spare parts and unprofessional repairs can cause this behavior of the iPhone or iPad display.

And many, many more. More accurately determine the cause of "iron" problems can only be in a good service center during the diagnosis. Fortunately, this procedure is almost always free. But I still really hope that you, dear reader, will solve the problem in any way from the first two paragraphs of this article, and it will not come to repair.

P.S. Leave questions in the comments - always happy! And of course, put "like" and press "+1" - this is also a joy :) Try it and you will like it!

Many are interested in why the phone turns off by itself. Answering this question is not as easy as it seems. After all, there are many reasons for such behavior. Do not immediately panic if you are overtaken by this problem. Try to figure out for yourself what real reasons this phenomenon. It is recommended to act by elimination method. But what are the points to look at? Why does the phone turn off by itself?

Departure

Very often, our today's problem appears due to the waste of the device's battery. It is not so easy to detect this phenomenon. After all, few people will independently begin to check whether the battery is well adjacent to mobile phone. Especially if there were no problems with it before.

To eliminate this possibility, remove the back cover of your mobile, then press the battery firmly against the phone. It remains only to check whether the device will turn off. Yes? Then the reason is clearly something else. No? Here you have found the source of the problem.

Battery

Why does the phone turn off by itself? The next reason for this behavior is nothing more than a battery problem. Its malfunction almost always leads to the fact that the mobile device starts to turn off and on on its own. Don't be surprised by this.

What to do in this case? Think about how long your phone has been running. Did you follow the recommended battery care instructions? Did you always start charging after a complete discharge of the "problem" component? If not, then the reason is most likely in the battery.

To eliminate this trouble, it is enough just to replace the faulty component. Usually, after purchasing a new battery, the phone stops turning off on its own.

Battery charge

The reasons don't end there. Why does the phone turn off by itself? Check battery charge. Not the most common, but the case that takes place in practice. It is the low battery of the phone that causes the device to turn off.

This situation is quickly resolved. All you need to do is charge your phone and then turn it on. You will notice how the problem will disappear by itself. From now on, just keep an eye on the battery charge. Then you won't have any surprises with your phone. In any case, you will be prepared to turn off the device.

Viruses

Unless the reasons for such behavior lie in something more serious. Why does my phone turn itself off and on? Under such circumstances, the battery of the device and its malfunctions are not always the source of the problem. Everything is much more serious.

The thing is that if you notice how the phone turns off on its own and then turns on, it's time to check the device for viruses. They are the cause of most gadget malfunctions. It is impossible to predict exactly how the phone will react to a particular virus.

To exclude infection, it is recommended to use special anti-virus programs for mobile devices. Or take the gadget to a service center. There they will help you not only to check the phone, but also to "cure" it if necessary.

Applications

On this list possible causes the emergence of our today's problem does not end there. Why does a Nokia phone or any other turn off? If all of the above options do not suit you, then you can think about installed programs and applications. Utilities often cause problems with the phone.

Several options are possible here. First - you have little space left on your mobile. In this case, you just need to free up space. Remove a few of the most unnecessary programs or games - and the problem will disappear by itself.

The third is the presence of malware. To fix the situation, you will have to find and fix the problematic utility. After that, you don’t have to wonder why the phone turns itself off and on (Samsung, Nokia or some other). After all, the problem will disappear. Its reappearance is possible when the gadget is again cluttered with programs.

System failure

Why does the phone turn off when charging and not only? The last common variant of this behavior is failures in the operating system of the device. They happen simply from time to time, and from viruses, and from the number of installed programs and applications. But most often, problems in the operating system are the result of incorrect firmware.

In order not to understand the correction of the situation for a long time, you simply need to reflash the gadget. Doing it yourself is not recommended. It is better to take the phone to a service center.

Usually after flashing all problems are eliminated. If even after that nothing helped, it's time to change the phone. Indeed, sometimes the reason lies in the malfunction of the equipment. In such a situation, only a complete replacement of the gadget will help. Now it’s clear why the phone turns off by itself. Fixing this problem is not as difficult as it seems. The main thing is to know where to start. By the way, you should think about firmware only after excluding all of the above reasons.
