Spontaneous turning on the smartphone screen. Why the phone suddenly turns off and what to do about it

07.12.2018 Frank 0 comments

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 on its own, 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 the operating system or user-generated problems, which usually arise from previously obtained root rights, can 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.

Spontaneous shutdown of the smartphone is a common problem that gadget owners regularly face. There are quite a few reasons why the phone suddenly turns off by itself. In this article, we will analyze the most popular of them.

When the phone turns off by itself, it creates some discomfort and interferes with normal operation and communication. Most often, this situation is faced by owners of old equipment, but in some cases, problems can also occur with new devices.

If this is a one-time issue, don't panic. The reason why Android turns off may be a banal failure in the system. But, if it is regular, the gadget is recommended to be taken to a service center.

However, some tasks can be dealt with at home. Complete instructions for problems different origin you will find below.

Power key not working

Mechanical malfunctions of the power button often cause the phone to turn itself off.

It is impossible to replace the key yourself at home. If this situation happened with a new gadget, there is a factory defect. When contacting the warranty service, the equipment will either be repaired or replaced with a new one.

But sometimes the breakage of the power button is preceded by bumps and falls. Modern smartphones are quite fragile, and even a slight impact on the ground can lead to malfunctions and malfunctions. The solution is the same - contacting the service center to replace the power off key.

You can also diagnose a malfunction at home. It is necessary to simultaneously hold down several combinations (for example, the volume rocker and mute) and look at the result. If it does not respond properly, then repair is needed.

Software failure

Another option - the most rosy for most owners of equipment - is a failure in the operating system. Errors in its operation may cause the cell phone to “hang” when performing a certain task and the inability to turn it off (or reboot) in the standard way. You can try to manually remove the battery and turn it on again. However, this method should not be abused.

Battery

If the phone constantly turns itself off, does not hold a charge and slowly charges, there is only one way out - to put another battery.

Of course, you can extend the life of an old battery for a few days by controlling the background and downloading a few special programs, but the battery will not fix it.

Moreover, a swollen or mechanically damaged battery can be life-threatening. There have been cases where a defective battery caught fire simply in the hands of users, or near their faces, causing severe burns.

Therefore, you should not delay with the replacement of the battery. This will not only affect the comfort and performance of the device, but also protect you from health risks.

Contact oxidation

Even those who carefully and carefully handle their smartphones are not immune from another type of mechanical damage - oxidation of contacts on the motherboard.

Moisture can get on contacts and junctions in the following ways:

  • With a sharp change in temperature (condensate is released).
  • Frequent carrying of equipment in hands in hot weather.
  • Getting caught in the rain.
  • Fall into a container of water.
  • And others.

Modern top models are already equipped with moisture resistance, but so far there is no such function in budget cellular phones. Moisture enters the phone through connectors, seams and speakers, becoming a catalyst for oxidative processes.

As in the previous cases, this problem cannot be dealt with manually, and it is recommended that the phone be repaired by the masters.

Removing excess from the system

Android is positioned as an open platform, so each user can personalize it to suit their tastes and needs. Most often this happens by downloading software from the Play Market.

Sometimes these are several applications, and sometimes their number reaches such proportions that the equipment simply cannot cope with the processor load, and constantly turns off.

The solution in this case would be:

  1. Check the authenticity of the operating system. Only installing a licensed Android OS ensures that the smartphone will normally cope with the tasks.
  2. Clear the storage of unnecessary programs. Optimal loading - up to 15 different applications.
  3. Check if the installed utility conflicts with the OS. You can find out on the forums, or in the reviews directly under the program page in the Play Market.

Screen breakage

Sometimes a broken screen is mistakenly perceived as a cellular failure to turn on. It is provoked by malfunctions in the gland, which, as a rule, are preceded by falls or contact of the device with water.

On most gadgets, the reboot is accompanied by a slight vibration response, which can be felt even if the screen does not show signs of life. It is worth checking for a response, if not, take it to the master.

Mechanical damage

Different types of “flights” are a real disaster for fragile devices. In most cases, they are brought to the service after the fall.

You can check the malfunction yourself by slightly bending the smartphone in your hands. If it turns off, then repair cannot be avoided.

If, after the impact, the back cover in the area of ​​\u200b\u200bthe camera or battery began to warm up, then most likely the root of the problem lies in the lagging of the thermal pad. It is possible to give final conclusions only after parsing the gadget.

Moral obsolescence

The average service life of a cell phone is 3-5 years, provided there are no breakdowns and careful attitude. But many people use them for much longer, so over time they have to visit repair points more often.

Equipment needs to be regularly changed and updated, because even now it is problematic to get spare parts for devices that were released 5-6 years ago. And some malfunctions of outdated models refuse to be repaired at all.

Therefore, when buying, pay attention to the OS version - if it is below 4.4, then the service will be in question.

Working in the cold

Gadgets are not recommended to be exposed to temperature fluctuations - this affects the battery. When working in the cold, many devices refuse to work and turn off on their own - this is normal practice. The range of suitable temperatures is indicated in the User's Manual.

Memory card

If, when installing a memory card, the smartphone does not work well, is buggy or turns off completely, it must be removed and replaced with another one.

Consider the reasons why MicroSD may conflict with the OS:

  • Speed ​​class incompatibility.
  • Factory marriage in the memory card.
  • Mechanical damage to the slot that slows down its operation.

Conclusion

Regardless of the source of the problem, it is not recommended to repair the smartphone yourself, especially if it is under warranty. Proper repairs that will not adversely affect further work, can only be carried out at the service center.

Video

Every year, dozens of new smartphone models are released by manufacturers. some as distinguishing feature can boast of their low cost, 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 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:

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

The list of possible causes 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.

The phone turns itself off and on. Why?

    There are 2 reasons why the phone can turn itself off and on. So, 1 reason is the phone is buggy (remember, maybe you dropped it or got water on it).

    Reason 2 is a software update.

    because it is buggy, maybe you dropped it or moisture got there!

    My phone reboots itself when several applications were launched at the same time, and then one of them was closed. It goes out and turns back on - there's nothing wrong with that, and this is from the very first day you bought it. i have nokia 5530

    As already mentioned above, the spontaneous turning off and on of the phone may be that the software is being updated. Or maybe you got some kind of virus. Or perhaps your battery contacts with the phone are loose, but then the phone would most likely not turn on by itself.

    My old phone has also recently started to sin with this. It turns itself on, it turns itself off, in general it became independent. The problem was in the battery, stack expiration date.

    The phone can also turn itself on and off without your knowledge due to the fact that it is heavily overloaded, they have caught a virus. And of course, there were problems due to the fact that he fell, and the contacts parted.

    something with the software, name the model more precisely and the possible reasons will be clearer. In general, this is more typical for smartphones, but also simple phones they sin with this, not as often as smarts, but still. I noticed that my smart n8 also sometimes spontaneously reboots, but after that it seems to me that it starts working better, faster. in repair for flashing.

    Everything is simple. Most likely your phone has been dropped repeatedly, after which the battery began to drain. Therefore, now, with any shift in the phone itself, the power is cut off and the phone turns off. Then the phone turns on again when the contacts are connected.

    Here it is very important to find out what operating system is in your phone, this happens more often with users of android phones, maybe your phone is unloaded with many programs that heavily load the phone’s RAM, I advise you to clean the phone of unnecessary files with the Clean Master program, or maybe there is a virus in the phone, well there is also technical reason such behavior of the phone (dropped, water ..)

    Turning the phone off and on frequently on its own may indicate external control of your phone. There are several reasons for external control:

    1. A brownie (telephone) has settled in the phone, and he always monitors the cleanliness of the processor

    2.Aliens have connected to your phone and they draw from it all the information that gets there for a certain period

    3. If cockroaches disappeared in the house with the advent of this phone, then they settled in nm and turn it off when they go to bed

    4.Your phone is endowed with artificial intelligence and indulges in electric discharges (analogous to drug addiction), which are formed at the moment the phone is turned on

    5. The phone has picked up a virus and thus tries to spit it out
