Why does the phone screen turn on by itself. Why does the phone turn off by itself? Possible causes and solutions to the problem. The phone screen lights up by itself - a problem with the operating system

Greetings! Spontaneously turning on the display on the phone - this problem can bring anyone to hysteria. It would seem that a 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 particular option.

In some cases, the Raise to Wake option may not work perfectly, try not to lift 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 top 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!

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. Full instructions for problems of different origins can be found 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 treatment. 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, which will not adversely affect further work, can only be carried out in a service center.

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).

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 simple phones also sin with this, not as often as smarts, but still. I noticed that my smart n8 also sometimes spontaneously It starts to reboot, but after that it seems to me that it starts to work better, faster. But if this happens very often, it’s better to take it to the sc if it’s under warranty or in repair for a 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 a technical reason for this behavior of the phone (fell, 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

Every year, dozens of new smartphone models are released by manufacturers. Some as a distinguishing feature can boast of their low cost, others high performance, others ergonomic design, the fourth 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 claiming 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 of screen differs 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:
