Spontaneous phone reboot. Why does my Android smartphone reboot on its own?

There are cases when owners of Lenovo phones are faced with the problem of spontaneous rebooting while taking photographs, while talking, launching various applications, etc. Why is this happening? Let's try to figure it out.

Most popular reasons

The device may reboot on its own for a number of reasons. The most common among them are:

  • Software glitches.
  • All kinds of damage due to external physical impact (the cause may be a fall or a strong blow).
  • There is moisture under the phone body.
  • Defective battery.
  • Damage to the printed circuit board.

What to do?

In order to normalize the operation of your device, you should take a number of actions that directly depend on the nature of the failure.

Reboot on power on

In cases where the phone reboots itself during startup, you should return the factory settings. Often, in this way the device’s functionality is fully restored. Each model has its own reset method.

Constant reboot

A similar reaction can be observed in cases of a damaged battery. To check this, you should take out the battery itself, place it on a hard surface and twist it. If the battery spins without any problems, then you need to replace it.

During telephone conversations

In cases where the device reboots during an incoming call, or during a conversation, you should contact the service center. The cause may be loss of battery-to-battery contact. You can also re-solder the connecting contacts yourself, but without the proper skills, this is quite risky.

When taking photos

It is not uncommon for the phone to reboot on its own when you turn on the camera. Such a breakdown is usually caused by a malicious program - a virus. You can get rid of it using an antivirus.

If your device rebooted itself, but you managed to determine why this was happening and solve the problem, write in the comments. This information will be useful to other users.

There are often situations when mobile devices have to be rebooted, but there are also cases when the phone reboots itself.

Let's try to figure out what can be done on our own to bring it back to life, and in what cases you need to rely on the experience of specialists.

Possible reasons

There are several main reasons why your phone reboots:

  • mechanical damage (due to impact or fall);
  • software failure;
  • battery failure;
  • malfunction of elements on the printed circuit board;
  • exposure to moisture on the device (entry under the device body).

Quite often, the reason for a sudden phone reboot is a failed signal power amplifier or battery. Energy consumption increases, which ultimately leads to an emergency reboot. Replacing these elements takes place in a matter of minutes and does not greatly impact the owner’s wallet.

The next leader in the number of calls from mobile device users to service centers is software failure. Applications previously installed on the phone may conflict with each other, or the owner of the gadget made a mistake in choosing firmware that did not fit the given phone model.

Normal moisture ingress can cause the device to reboot, along with mechanical damage resulting from the device falling from a height, which often damages the main or printed circuit board.

What to do if it reboots

A fairly common problem with modern smartphones is spontaneous rebooting. Below are the steps you need to take to restore normal system operation.

All the time

The reason may lie in a damaged battery. To verify this, just remove the battery from the device, place it on a hard surface and twist it. If the battery rotates easily, it means there is a bulge somewhere or the battery is already starting to swell.

If this is exactly the problem, then you should take a look at your nearest service center, since swollen batteries cannot be repaired.

In cases where the battery is in perfect order, it is necessary to update the software, and at the same time the previously installed applications. If the gadget runs on the Android platform, it is recommended to go to Google Play and select the necessary updates. The lazy ones can simply click “Update all”, but it is better to look through the proposed applications to avoid garbage in the phone.

After updating the applications, you should start updating the system. If this does not help, then you need to contact a service center.

When turned on

When the phone reboots spontaneously when turned on, you can use the following methods:

  • reset settings to factory defaults. The chances of restoring the functionality of the device in this way are very high. Each device has its own method for returning default settings; all this can be found in the instructions for the device;
  • remove the battery and then put it back after 30 minutes.

Perhaps the problem is that the phone is simply overheated; there are also cases of the device’s power button sticking. If none of the proposed options produces results, you need to reflash the gadget. You can do this on your own or contact service workers.

When talking

In the case where the phone reboots when there is an incoming call or during a conversation, there is a high probability that the battery is losing contact with the device. This is explained by the fact that during a long period of operation, a slight play in the rear surface of the battery occurs (the gap between the connecting elements).

When using the gadget every day, the case shakes, which causes the contacts to disconnect. To check if this is the root cause of the device malfunction, you need to shake it several times. If the device reboots again, then you need to resolder the connecting contacts. It will be easier to send the device for service if it is under warranty.

The next reason for the device to not work correctly may be a software glitch.

There are three possible solutions to this problem:

  • go to standard settings;
  • firmware update;
  • service center (if none of the above options helped).

After update

The mobile device may restart after accepting the necessary updates. However, there are pitfalls here too.

To get started you need:

  1. turn off the device and remove the battery from it;
  2. After 15 minutes, put it back in place and turn on the device again.

If this procedure does not produce results, then be more careful about what updates you install.

Some applications may block the normal operation of the device or conflict with each other. If before the updates you did not notice any deviations in the operation of the gadget, then you need to return to the factory settings and reboot the device again.

The cause of the gadget’s incorrect operation may also be malicious software that got into it along with updates. In this case, you can also use the above tips, if they do not work, then you should give the phone for flashing.

When turned on

Another common type of problem is the smartphone rebooting when you turn on any application or function. The steps required to resolve it are described below.

Cameras

It is not uncommon for mobile devices to reboot after turning on the camera. Owners of highly advertised iPhones especially often suffer from this problem. The cause of the problem may lie in some application that “caught a virus.” It is recommended to run an antivirus, find the cause of concern and restart the system.

If this does not help, then you should return to the standard settings, but before that you need to make a copy of all the necessary documents and contacts. The problem may also be specifically with the device of the camera itself; after an impact or fall from a height, the cable may come off the phone.

The method of treatment is to open the gadget and put it in place. Craftsmen often do this on their own.

To understand what caused the reboot, you should remember whether the device was ever dropped into water or other liquid. In such cases, the device may periodically reboot, which does not irritate the owner much, but this is just the beginning.

If your phone has recently experienced the beauty of water treatments, then you should disassemble the gadget again and dry it thoroughly. After such tests, rebooting when the camera is turned on is not the worst thing that could happen to it.

GPS

What should I do if my phone reboots after turning on GPS?

There are several options to solve the problem:


Bluetooth

This problem occurs quite often among owners of HTC phones. To solve this, you can reflash the phone or simply never use the multimedia transfer function. However, after flashing the device, it is guaranteed to work as before. You can also use a simple reset.

As for disabling the annoying function, everything is not so simple here either. Due to the constant reboot, the user only has a couple of seconds to turn off Bluetooth. So, you need to turn off the device, take out the SIM card and memory card. This way the gadget will work faster, thanks to which the phone owner has 10 seconds to turn off Bluetooth, after which it will reboot again, but for the last time.

When launching applications

A similar incident often occurs with Nokia phones.

To understand the reason for the reboot you need to:


  • try not to use registry cleaners;
  • do not download too “heavy” applications;
  • use only official software.

When connected to a computer

Malware can cause your phone to reboot when connected to a PC. Check both devices for viruses. If you were unable to eliminate the threat on your phone using an antivirus, then you should reinstall the software or reset the settings.

Do not forget that the artisanal flashing method can result in a breakdown that can no longer be fixed. If the problem has not been resolved using conventional methods, then you should contact a service center.

Phone keeps rebooting to Android

To get your Android phone back to normal functioning, you need to check the latest update date. This applies not only to applications, but also to the system itself.

Happy owners of Samsung phones can conduct an experiment - try switching to safe mode. If the gadget does not reboot, then we can safely say that the device is wearing out one of the installed applications.

These are the consequences of malware. After deleting the application, you must restart your device.

Try to treat your equipment carefully and with care; of course, mechanical damage can be corrected, but it entails more serious problems. Contact service center specialists for help; this is the only way to guarantee that you will get a properly working device back.

Android phone keeps rebooting

What to do if your Android phone keeps rebooting

An unauthorized reboot of an Android smartphone is usually associated with unstable operation of an application on the device. There is one factor that affects the operation of a smartphone: if you download and install a lot of applications and then delete them and then do the same thing, then after a while you will notice that Android does not work so fast, and sometimes it starts to freeze. If you practice this, then the best solution would be a smartphone.

It is best, of course, to download exactly those applications that have already been verified, have good popularity and a high rating.

The question arises why the smartphone freezes or reboots after deleting applications. There is a very large number of applications on Google Play: some are “completely safe” - they do not affect the operation of the device in any way, while others may conflict with similar ones or leave a lot of garbage after removal, thereby causing crashes and reboots.

If after installing the application the smartphone starts to reboot, this should alert you. It is better to delete such an application immediately, and make sure that all system folders have also been deleted from the device.

Disabling the SD card during spontaneous reboots of the Android device

If you notice that during any operation your smartphone starts to turn off and turn on again. Disconnect the memory card on the device and try again the action that caused the reboot. If you find that the memory card is the cause. Transfer the data (photos, videos and other data) to your PC and format the card. For more details on how to disconnect an SD card and format it, we wrote in

Some users are faced with an unpleasant situation - their phone constantly reboots, which prevents them from performing any tasks on their mobile device. A reboot can occur at different stages: when turning it on or off, during a conversation, when connecting to a computer, etc. In any case, all users have one question - what to do if the phone constantly reboots, and how to fix this problem.

Reasons for rebooting

Sometimes, due to a software glitch, users have to reboot their phone. But if the device restarts on its own, it does so for one of the following reasons:

  • Failure of the battery or signal power amplifier.
  • Serious software glitch.
  • Mechanical damage.
  • Exposure to moisture.

Most often, users encounter failure of the signal power amplifier, which leads to increased energy consumption and subsequent emergency reboot. Replacing an amplifier or battery is done quickly and does not greatly impact the budget of the smartphone owner.

In second place in terms of “popularity” is software failure. The reason for its appearance may be a conflict between the device and installed applications or user errors when flashing the firmware.

Mechanical damage or exposure to moisture also negatively affects the condition of the mobile device: the phone does not turn on or constantly reboots.

Troubleshooting

Try to determine at what point the phone reboots - this will help you quickly diagnose the cause and fix the problem. All further actions depend on this, so be careful.

Restarts constantly

If the phone reboots constantly, then first check the battery - it may be faulty. Take out the battery, place it on the table and try to twist it.

If, after a slight push, the battery spins on the table for a long time, then it has a bulge, that is, it swells. In normal condition, the battery will not spin - it will stop almost immediately after the shock.

Swollen batteries cannot be repaired, so you will have to purchase a new battery. But after installing it, the reboot problem should be successfully resolved.

If the problem is not the battery, then try updating all applications and software. Start with the apps: if they have updates, install them. If this does not help, take care of the phone software - update the system yourself or contact a service center.

When turned on

If your phone restarts immediately after turning it on, try the following troubleshooting methods:

Sometimes the phone reboots due to overheating or the “Power” button sticking. If none of the above reasons suits you, you can try to reflash your smartphone.

During a conversation

If the smartphone restarts when there is an incoming call or during a conversation, then the most likely reason is the loss of contact between the battery and the mobile device. This can be explained by the appearance of a small gap between the connecting elements as a result of prolonged use or mechanical stress.

To make sure that the reason for the reboot is a loss of contact between the battery and the phone itself, shake the device several times. If it turns off or reboots, contact a service center or re-solder the contacts yourself.

  • Reset to system parameters.
  • Firmware update.

If the above methods do not help, then you will have to contact a service center to save your phone.

After update

If you installed updates, but instead of starting to work better, the phone now constantly restarts, then try first removing the battery and putting it back after 15-30 minutes.

After updating, some applications block the normal operation of the mobile device or begin to conflict with each other.

If you didn’t notice any problems with your phone before the update¸ then try rolling back to the factory state - this should help solve the problem.

The constant restart can also be caused by malicious software. If your smartphone gets a virus, clean its system with an antivirus or reset the settings to factory state and reflash the device. By the way, if the phone reboots when connected to a computer, then here you also need to think about checking both devices for viruses.

When launching applications or modules

Another common problem is that the phone reboots when launching modules or individual applications. For example, the iPhone restarts when the camera is turned on - the cause of this problem often lies in a virus infection.

If the antivirus scan does not reveal anything suspicious, then make copies of all important files and return the phone to standard settings. In addition, on some models it may be useful to correct errors on the memory card or replace it altogether.

The reason for the reboot when the camera is turned on can also be mechanical damage: for example, after an impact the cable came loose. You can fix this problem yourself, but if you do not have sufficient knowledge, then it is better not to open the case of your mobile device.

GPS and Bluetooth

Sometimes the phone reboots due to Bluetooth or GPS modules. There are few options to solve the problem:

Reflashing will also help fix the problem - the main thing is to do it correctly, without making any mistakes.

Applications

Often the smartphone restarts when you turn on an application. To resolve this unpleasant situation, try the following:

  • Make sure the battery is in good condition (not swollen, leaking, etc.).
  • Remove the battery, wait 15-20 minutes and install it back.
  • Reflash your mobile device.

To avoid hardware and application conflicts, use the following guidelines:

  • Do not use programs that clean the registry on your phone.
  • Do not download excessively “heavy” applications so that the smartphone does not work at the limit of its technical capabilities.
  • Use official software, without cracks, builds or home releases.

If it is not possible to identify and eliminate the cause of the reboot, do not delay contacting the service center: repairing your phone usually costs much less than a new device.

A smartphone or tablet may reboot on its own for several reasons. Check the recommendations for each one in turn.

One-time software glitch

Don't worry if your device reboots rarely - once every week or two.

Firstly, this may be due to accidentally pressing the Power button. If you keep it pressed for a few seconds, the device
will reboot.

Secondly, over time, the battery wears out and can produce unstable voltage, especially under heavy loads. This is a natural process and will simply need to be replaced in the future.

UBANK application

On some devices (Galaxy A8/A8+, S8/S8+) there were problems with the pre-installed UBANK application. If you have such an application on your device, disable it.

If the device stops rebooting on its own, the problem is in the application. Try enabling it later if you need it.

If your device continues to reboot after disabling UBANK or you don't have such an app, move on to the next recommendation.

If your device reboots once a week at a specific time, the Auto Reboot feature may be enabled. Check this: Menu - Settings - General settings - Reset - Automatic reboot should be turned off.

If automatic reboot was turned off or this did not help, move on to the next recommendation.

Impact of installed applications

The device may restart due to applications that were installed after purchase. One of the installed applications freezes and stops the operating system. To reset this “error,” the device reboots.

Check whether installed apps are interfering with your device by booting your device into Safe Mode. In this mode, all downloaded applications are disabled and only those that were installed at the factory work.

If the device works fine in Safe Mode, some downloaded app is to blame. Unfortunately, there is no way to determine which one exactly, so we recommend deleting one at a time, starting with the last installed or updated one. After uninstalling the application, monitor the device's operation. If the problem goes away, the problem was with the uninstalled application. If it doesn’t disappear, it wasn’t his fault, delete the following.

If your device still restarts in Safe Mode, move on to the next recommendation.
