A common problem with Android: a smartphone (or tablet) periodically spontaneously reboots. Reboot can happen:
- when working in one or in some applications;
- during the installation or removal of applications (in this case, the installation or removal procedure is interrupted);
- at rest.
Removing apps
Most often, unauthorized reboot is associated with the unstable operation of one of the applications. The pattern here is simple: the more you install and uninstall apps, the faster Android will start to glitch. If you use 3-5 programs, then your device will be able to work for a long time without problems. And if you install a new game every day, then delete it and download the next one, then you will have to reset the settings more often than in the first case.
By and large, in Android everything is about the same as in Windows. One application can be installed and removed without harm to the operating system. The other one will cause crashes, and after deletion will leave behind a bunch of garbage. Often it depends on the skill of the developer and the purpose of the application. If the goal of the game is to trigger ads on your smartphone and turn your device into a money-making machine, guess what the quality of the game itself will be and its environmental friendliness for Android.
Delete applications after installation of which the smartphone started to reboot. If this cannot be done in normal mode, enter safe mode ().
Virus check
Viruses and malware can cause crashes and reboots. To check the system fit:
Dr.Web v.9 Antivirus Light
Page in the Play Store: https://play.google.com/store/apps/details?id=com.drweb
Anti-Malware Mobile
Play Store page: https://play.google.com/store/apps/details?id=org.malwarebytes.antimalware
Disabling the memory card
After disconnecting the SD card, repeat the operation where you are having a crash. If the problem no longer exists, save the contents of the card to your computer, format it, and try inserting it into your device again.
Reset settings
Unfortunately, this radical method is often the only way to revive the operation of a smartphone or tablet. In general, Android periodically needs to be reset in the same way that Windows periodically requires reinstallation. If you are a guru, you can get into the wilds of the Android system from the command line, find the cause of the problem and fix it without wipe. But if it is important for you to restore the normal operation of the gadget as soon as possible, it may be easier to do a Factory Reset.
The following is interesting: quite often after a complete wipe (resetting the settings), you log into your Google account and all the applications that were installed at the time of the reset start to be restored on your device ( My apps in the Play Store). But at the same time, the device starts to work absolutely normally. If this happened to you, it can be assumed that most likely the reason for the reboots was system problems caused by a long-deleted application.
Read about how to reset the settings.
If your device reboots cyclically after an unsuccessful flashing, a reset is indispensable here.
Finding a hardware fault
This is the worst possible reason. The device may reboot due to such iron factors as:
1. Overheating
If the reboot occurs while playing a game, watching a movie in high quality, or while working with a resource-intensive application, the problem may be overheating. Find out what the temperature of the gadget is. AnTuTu will help you with this or even:
2. Damage caused by a fall or liquid spill
If your gadget has been in such situations, take it to the official service center for diagnostics. Otherwise, you will not fully understand what the reason for reboots is.
3. Factory marriage
For example, if in a new device with the back cover removed, there is a smell of burning. Here the advice is the same: to the store with a request to replace it or to a service center with a request to fix it.
1) Do not install unverified applications (or install, but be prepared for reboots, freezes and other surprises).
2) The fewer applications you install, the longer Android will live without resetting the settings. This does not mean quantity. simultaneously installed, and the total number ever established games, programs, utilities.
3) The more applications, the more difficult it is to identify faulty and unwanted ones - those that kill the system, cause glitches, contain malware, etc.
4) If your model is "hot" by itself, try not to give a big load in hot rooms.
A smartphone or tablet may reboot on its own for several reasons. Check out the recommendations for each one in turn.
One-time software failure
Don't worry if your device rarely reboots - once a 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, in the future it will simply need to be replaced.
UBANK application
Some devices (Galaxy A8/A8+, S8/S8+) experienced issues with the pre-installed UBANK app. If your device has such an app, 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 the device keeps restarting after disabling UBANK, or if you don't have such an app, move on to the next recommendation.
If the device reboots once a week at a specific time, the Auto Reboot feature may be enabled. Check this: Menu - Settings - General settings - Reset - Automatic restart should be turned off.
If automatic restart was turned off or this did not help, continue to the next recommendation.
Impact of installed applications
The device may restart due to applications installed after purchase. Some of the installed applications "freeze" and stop the operating system. To reset this "error" the device reboots.
Check if the installed applications are affecting the operation of the device by booting the device in safe mode. In this mode, all downloaded applications are disabled and only those that were installed at the factory work.
If the device works normally in safe mode, some downloaded application is to blame. Unfortunately, there is no way to determine which one, so we recommend deleting one at a time, starting with the last installed or updated one. After uninstalling the application, monitor the operation of the device. If the problem is gone, then it was the remote application. If it didn’t disappear, it wasn’t about him, delete the next one.
If your device still restarts in safe mode, continue to the next recommendation.
Some users are faced with an unpleasant situation - their phone is constantly rebooting, which prevents them from performing any tasks on their mobile device. Reboot can occur at different stages: when turned on or off, during a conversation, when connected 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 reboot
Sometimes users have to reboot their phone as a result of a software glitch. But if the device restarts on its own, then it does this for one of the reasons listed below:
- Failure of the battery or signal power amplifier.
- Serious software glitch.
- Mechanical damage.
- Moisture exposure.
Most often, users are faced with the failure of the signal power amplifier, which leads to an increase in power consumption and subsequent emergency reboot. Replacing an amplifier or battery is quick and does not hit the budget of the smartphone owner much.
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 during flashing.
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 is constantly rebooting, then first of all check the battery - it may be out of order. Take out the battery, put it on the table and try to twist it.
If, after a small push, the battery spins for a long time on the table, then it has a bulge, that is, it swells. In the normal state, the battery will not spin - it will stop almost immediately after the push.
Swollen batteries are beyond repair, so you will have to purchase a new battery. But after installing it, the problem with the reboot should be successfully resolved.
If the problem is not the battery, then try updating all applications and software. Start with apps: if there are updates for them, install them. If this does not help, take care of the phone software - update the system yourself or contact the service center.
When turned on
If the phone restarts immediately after being turned 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 call
If the smartphone reboots during an incoming call or right during a conversation, then the most likely cause 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 long-term operation or mechanical stress.
To make sure that the cause of 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, then contact the service center or solder the contacts yourself.
- Reset to system parameters.
- Firmware update.
If the above methods did not help, then you will have to contact the service center to save the phone.
After update
If you have installed the updates, but the phone, instead of starting to work better, now constantly restarts, then try to first remove the battery and replace it after 15-30 minutes. 
Some applications after the update block the normal operation of the mobile device or begin to conflict with each other.
If before the update you did not notice any problems with the phone, then try to roll back to the factory state - this should help solve the problem.
Malicious software can also be the reason for the constant restart. If a virus has hit your smartphone, clean its system with an antivirus or reset the settings to the 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 virus infection.
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 you turn on the camera - the cause of this problem often lies in a virus infection.
If the antivirus check did not reveal anything suspicious, then make copies of all important files and return the phone to standard settings. In addition, on some models it is 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 the impact, the cable came off. You can fix this problem yourself, but if you do not have sufficient knowledge, then it is better not to open the case of the mobile device.
GPS and Bluetooth
Sometimes the phone reboots due to Bluetooth or GPS modules. There are few options for solving the problem:
Flashing will also help to fix the problem - the main thing is to carry it out correctly, without making any mistakes.
Applications
Often, the smartphone restarts when you turn on an application. To fix this annoying situation, try the following steps:
- Make sure the battery is in good condition (not swollen, leaking, etc.).
- Take out the battery, wait 15-20 minutes and put it back in.
- 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 the official software, without cracks, builds and home releases.
If it is not possible to identify and eliminate the cause of the reboot, do not delay contacting a service center: repairing a phone is usually much cheaper than a new device.
Phones are devices that almost all citizens now have. It is quite easy to manage such a gadget. But only from time to time various problems can happen to him. For example, what if your phone is constantly rebooting? And it happens spontaneously and for no reason, as you think. There are a lot of options for the development of events. What should you pay attention to first of all? How to fix the situation as soon as possible?
Software failure
So, the first and most common reason that the phone is constantly rebooting is the failure of the installed software. Or, as they say, the operating system. As practice shows, very often malfunctions in the installed software cause problems with the device's performance.
How to be in such a situation? First, try turning the phone off and on yourself - the software glitch can be fixed. As a result, the problem will disappear.
Secondly, flash the device. It is advisable to take the phone in this case to specialized service centers. There you will be reinstalled the operating system on the gadget, and the problem will stop bothering you. Everything is easy and simple. But not always. And in some cases, flashing is not required. After all, there are a lot of reasons why the phone is constantly rebooting.
Soft
Is your phone constantly rebooting? Remember what programs and applications you have installed recently. They may be the cause of this problem.
The fact is that sometimes incorrectly installed programs cause system crashes. As a result, the phone starts to reboot. The only true solution is to detect a "malicious" application and then remove it.
If you really need the program, just try deleting it and reinstalling it. Also a good way, but it does not give any guarantees for success, keep this in mind. Most likely, you will have to get rid of the software once and for all. Usually this is not such a problem - you just need to find an analogue of the remote program that will not cause crashes and malfunctions.
Battery
Phone constantly rebooting (Samsung or any other)? Don't be afraid and don't panic. Understanding the reasons for this phenomenon is not so easy, but it is possible to do it without outside help.
Pay attention to the battery of the gadget - this is a very important element for the functioning of the device. If something is wrong with it, the phone will start behaving in an unpredictable way. As practice shows, in the event of a battery failure, the device usually either reboots spontaneously or turns off for no reason.
What to do in this case? If you are sure that the battery is the cause of the problem with the gadget, replace it. Just purchase a new battery and insert it into your device. Charge the battery and look at the behavior of the phone. Most likely the problem will go away. Not? So, the reason for rebooting the smartphone was something else. What other scenarios are there?
Moisture
Sony phone keeps rebooting? And indeed, any other smartphone? Moisture may be the reason for this. In rooms with high humidity, gadgets can behave unpredictably. And if you recently wet your phone, then there is nothing to be surprised at the problem! Why? Because the device, in principle, could not turn on. And rebooting in this case would not seem to be a problem at all.
If you have suspicions that the smartphone is starting to restart due to high humidity, just try to return to normal as soon as possible. As soon as you leave a place with high humidity, the gadget will work normally.
Phone keeps rebooting? What should I do if the reason for this is moisture on the device? There is only one way out - to dry the smartphone as soon as possible. Take it apart. Next, thoroughly dry all parts with a towel or napkin. In some cases, you can use a hair dryer to dry quickly. Once all the parts are 100% dry, assemble the gadget and see if you can fix the problem. Usually, with operational actions, the result will not be long in coming. Now many phones tolerate moisture well. Therefore, there is no particular reason to panic.
Settings
LG phone reboots constantly (and in general, any other gadget model)? In this case, you should pay attention to the system settings of your device. Often they become the cause of many problems with smartphones. The phone can turn off, reboot, slow down. All this points to the downed settings.
You can edit them yourself so that the system does not reboot. This is difficult to do, so many prefer the radical method - flashing. The most difficult and most efficient process. It is not recommended to implement it on your own, seek help from specialists. If the reason for constant reboots lay precisely in the downed settings, then after flashing this phenomenon will disappear.
Space
What else can you pay attention to when the phone constantly reboots? The amount of information on the gadget. Take a good look at how much space is left both on the memory card and on the built-in "place" of information storage. What for?
The problem is that often the fullness of the memory in any gadget leads to problems. Fortunately, you can fix the situation easily and simply - just clean your smartphone. Remove all old and unnecessary applications, media files and programs. And make it a habit to clean your phone space from time to time. So you can return the device to the right track, and also prevent the problem from reappearing.
By the way, if you are wondering why the phone is constantly rebooting, look at the total capacity of your memory card, if any. Each smartphone runs smoothly only with a certain amount of extra space. If a larger memory card is inserted into the gadget, the performance is impaired. As a result, there are crashes, sudden reboots and turning off the gadget. Therefore, only use memory cards that meet the maximum capacity for your phone model.
Overheat
There is another not very dangerous and easily fixable reason for a sudden restart of the smartphone. In principle, the same option is relevant for other gadgets (like computers). It's about overheating. As soon as the device heats up to a certain temperature, it either turns off or reboots. It is quite normal - so the system saves itself from failure.
The solution to the problem is simple - just stop bringing the device to overheating. Disable programs running in the background, do not use the phone continuously for too long. Only in this way will you be able to normalize the operation of the gadget. Try not to keep it in the sun.
Viruses
Is your phone constantly rebooting? What to do in this case? Check it for viruses. A phone infection often causes a spontaneous reboot of the device. In this case, various antiviruses will help. Or service centers.
If you find viruses on your mobile phone, remove them. After treating the phone, all problems will disappear by themselves. Viruses are found every day on smartphones more and more often. Therefore, this option should be checked first.
Time
In some cases, if the phone constantly reboots, you just need to change it. Each device has its own lifespan. And when it comes to an end, various failures and malfunctions appear. There is no way to fix them. In order not to waste time, take the phone to a service center - they will help you find the source of the problem, and also tell you if it makes sense to fix it.
Wear and tear on equipment is inevitable. Therefore, if your phone has been running for about 5 years and then suddenly starts to reboot, it is quite possible that it needs to be changed.
There are times when owners of Lenovo phones encounter the problem of spontaneous rebooting while taking pictures, talking, launching all kinds of applications, etc. Why is this happening? Let's try to figure it out.
The most popular reasons
The device may reboot on its own for a number of reasons. The most common among them are:
- Software failures.
- All kinds of damage due to external physical impact (cause may be a fall or a strong blow).
- There is moisture under the phone case.
- Failed battery.
- PCB damage.
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 breakdown.
Reboot at power on
In cases where the phone itself reboots during power-up, you should restore the factory settings. Often, in this way, the operability of the device is completely restored. Each model has its own reset method.
Permanent reboot
A similar reaction can be traced in cases of a damaged battery. In order to check this, you should get the battery itself, put it on a hard plane 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 reason may be the loss of contact between the battery and the battery. You can also solder the connecting contacts yourself, but without the proper skills, this is quite risky.
When photographing
It's not uncommon for a 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 with an antivirus.
If your device rebooted itself, but you managed to find out why this is happening and solve the problem, write it down in the comments. This information will be useful to other users.
