In this article we will look at the reasons why Android reboots itself and how to solve them. Let's take simple steps that in some cases can save you from going to service center, which means they will save time and money. This breakdown is typical for famous and not famous brands, as well as old phones. Causes of spontaneous Android reboot can sometimes be corrected at home, but some can only be dealt with at a service center if the phone or tablet can still be saved.
Reasons related to smartphone battery:
- Poor battery contact or oxidation;
- The battery is not properly distributing signals to the modules;
- Swollen or otherwise mechanically damaged battery;
- Damaged power charging controller due to the use of a non-original or cheap charger;
- The battery has served its purpose;
- Low quality non-original battery;
- Moisture and dirt getting under the housing.
Only replacing the battery with another one will help, since they cannot be repaired.
Other technical reasons:
- Signal power accelerator failure;
- Power button sticks;
- Damage to the main or printed circuit board, other spare parts (after getting wet, falling).
Software reasons:
- The presence of applications that conflict with each other;
- Firmware problems (especially true if you manually installed a custom, inappropriate, beta version of the OS or the release occurred recently);
- Smartphone overheating;
- Virus on the device.
That's why the phone reboots android by itself.
What to do if your Android phone keeps rebooting. Application problems
Do you have several antiviruses, cleaners, camera applications, GPS? There may be an algorithm conflict. Therefore, you should not install too many programs, especially if you are not sure that you need them. Launch in safe mode. If the reboots stop, remove unnecessary applications. Check your device for viruses. Have you noticed your smartphone overheating and taking a long time to respond? Perhaps you downloaded something from unverified sources. More specifically, the presence of a virus is indicated by rebooting the phone when launching an application (for example, a camera). The highest quality antiviruses for Android: Norton Security& Antivirus, Sophos Antivirus & Security, Bitdefender Mobile Security& Antivirus, Antiy AVL, Cheetah CM Security. No malware? Do you have a lot of “heavy” applications that often work simultaneously, and are you already tired of notifications about the lack of memory? Try clearing the program cache (“Settings” – “Applications” – any application from the list – “Clear cache”), removing unnecessary ones. You can use one of the cleaning programs: Clean Master (if you have an antivirus, it may conflict), DU Speed Booster & Cleaner, GO Speed.
If you suspect an OS malfunction
If you think that there is nothing suspicious or new in your files, and the previous tips did not help, reset the settings to factory settings, after saving important data to external storage(the flash drive is suitable), reset the settings to factory settings. This advice is suitable when you were unable to identify the problematic software yourself or there is a suspicion of damage system files. Section “Settings” – “System” – “About phone” – “Software update”. Why does the phone constantly reboot on its own android? There may be problems with the firmware. To update it, go to “Settings” - “About device” - “System updates” - click “Check now”. Agree to the software update. The smartphone will reboot itself after the operation is completed. If there are no updates, look for information about your smartphone model along with the Android version. Perhaps the problem is in the firmware. You will have to wait until they fix it or find and install an unofficial version if you are confident in your actions. Reboots while turning on bluetooth. Change the phone firmware. If it reboots too quickly for this, remove the SIM card and memory card to make the device work faster. Turn on your phone and quickly turn off Bluetooth. If the device reboots, then you will not encounter this again. If necessary and desired, you can install third party application file transfer.
Actions in case of physical damage to the device
In case of technical damage, most likely you need to contact a service center for help. There are some things you can still try to do yourself. There may be a problem with the memory card. Take it out and perform the action that usually triggers a reboot. If this does not happen, format the memory card. Did not help? If possible, replace with a new one. Remove the battery and wait 30 minutes. This will help against overheating, which could be the cause of reboots. Android phone keeps rebooting when shaken. In this case, the battery loses contact with the contacts. This can happen if the phone is used frequently. You need to resolder the contacts. Of course, it is better to do this in a service, but you can do it yourself. Soldering is a rather delicate process that is worth considering separately. Notice dirt on the battery terminals? Remove the battery and wipe the connections with cotton wool soaked in contact cleaner or spray. Extend the contacts slightly for a tighter connection with the battery terminals. The phone reboots after turning on the GPS and cannot start? There are several possible solutions. Replace the SIM card if it is much older than the smartphone.
It may be a problem with the memory card or settings that need to be restored to factory settings.
The Samsung phone reboots itself. In addition to Android, Samsung smartphones were produced running Windows Phone. For the former, the problem of spontaneous reboots is more common. Solutions are the same as in the previous paragraphs. To roll back the firmware if necessary, visit the manufacturer’s official website: http://samsung-updates.com/device/
In general, regular random reboots of the phone should indicate some serious problems in the phone. Is it so? The answer is no, not always. There can be many reasons - from incorrect settings before serious failures in the OS or breakdowns of components.
Reboot at a specific time
If the phone restarts itself, but only at a certain time, it means that you have an active option in the settings for automatic reboot according to a schedule. How to disable it:
Reboot in the cold season
If your smartphone restarts when you are outside in the cold season, there is nothing surprising here. Modern phones very sensitive to low temperatures. Try not to take it out of your bag or pocket when you're outside to keep the device relatively warm.
The phone is overloaded with a large number of open programs: the equipment cannot handle it
If you have too many programs open on your phone that the device cannot handle at the same time, it will reboot in order to, so to speak, “shed” the extra load. Even smartphones have an instinct for self-preservation.
From large quantities open applications The processor may overheat, hence the same restart to reduce the temperature.
What to do in this case? Determine for your phone the optimal number of applications with which it can easily work without consequences in the form of a restart.
As new programs are launched, reduce the number open source software(close unnecessary ones). This is very simple to do: hold down the “Menu” button at the bottom and in the “Task Manager”, swipe right or left the windows of applications that you will not use for now. Or another option - buy new smartphone with more powerful RAM and processor.
Close any apps you are not currently using
Device memory problems
The device memory may be completely full. If the phone does not have enough space to save files during operation, the system will periodically reboot. This helps her free up at least some space by deleting temporary documents that are needed only for the current session.
Check how much free memory your Android currently has, and clear it if necessary:
It would also be a good idea to clean the system from unnecessary files. To do this use special programs eg CCleaner.
The problem may be in the SD card if, for example, the phone starts to reboot while launching the gallery, camera, or when taking photos. The SD card may also be full. In this case, it needs to be freed from unnecessary user files - music, photos, books. Conveniently delete all files on your computer (connect your phone to PC using USB).
The memory card may be damaged. In this case, you need to temporarily change the storage location of the photos taken (instead of a memory card, install an internal drive). After that, connect the phone or the flash drive itself (using a flat adapter) to the PC, move all the files to the computer if possible and format the card. Even if formatting does not help, you will need to replace the flash drive with a new one.
Format the flash drive that was in your phone
There may also be viruses on the flash drive - we will talk about them in the next section.
Virus infection
Update the threat database in your antivirus on your smartphone and run a deep scan. You can also use mobile scanner Dr.Web Light.
Wait for the scan to complete
If viruses are found, remove them immediately. Restart the phone yourself and check how it works.
Incorrect or broken firmware
Something may trigger a restart in the operating system (firmware) itself. You can start by resetting your phone to solve the problem:
If restoring the original Android settings does not help, you should reinstall the phone OS. For this, it is better to go to a service center.
Battery problems
The battery may overheat: just like with the processor, the phone itself will forcefully reboot the phone to allow it to cool down. How can you help your device in this case: turn off the phone itself, remove the battery for 20 - 30 minutes so that the temperature drops. If the battery is non-removable, simply leave the phone turned off during this time.
The battery may be damaged. This may cause it to overheat. What causes a battery to deteriorate:
- using a non-original charger that does not suit the parameters of your phone (too much current, for example);
- charging using a damaged USB cable;
- using the phone in extreme cold;
- moisture entering the device, which began to oxidize the contacts.
Inspect your battery: if it is swollen, it needs to be replaced immediately. If the battery is “sewn” into the device, visually evaluate the entire case to see if there are any bulges on it. In this case, the best thing to do is take the phone to a service center so that the specialist can tell you for sure whether it’s the battery.
Look at the overall health of the battery
Mechanical damage or defects
If you have already tried everything, but nothing has helped, you should contact specialists at the service center to find out the reasons. Most likely, this is a hardware failure or a firmware malfunction. In the first case, you definitely won’t be able to do anything on your own.
Remember if your phone has fallen recently. If yes, but there are no visible damages on it, this still does not mean that the fall was without consequences - the breakdown may be internal.
A specialist at the service center will disassemble your phone, tell you what’s wrong, and offer solutions.
What could be on the verge of failure: processor, power controller, GPS module, radio module (for example, if the phone began to reboot after connecting a SIM card), various contacts. An example of a situation for contacts: the phone reboots during conversations due to the fact that the device and the battery are connected by weak contacts. In this case, you will simply need to re-solder them.
You need to look for the cause of the problem step by step. First try to observe how the system works with a certain number of programs enabled. If your phone overheats, reduce this number - use only the most necessary utilities. Try checking your phone for viruses. Also reset your phone to factory settings. If all else fails, go to a service center - some hardware part of your smartphone may be damaged.
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 quickly, and sometimes it starts to freeze. If you practice this then the best way out there will 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. IN Google Play A very large number of applications, some are “completely safe” - they do not affect the operation of the device in any way, while others can conflict with similar ones or leave a bunch 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.
Another option for checking is the Device; read more about how to do this in our article.
Android keeps rebooting - it's worth checking for a virus
One of the obvious options for why a smartphone reboots is that the device is infected with viruses and all sorts of malware. To check your phone for a virus, use applications that analyze the entire system.

Frequent rebooting of the smartphone as a result of a hardware malfunction
Reasons why you will have to contact a service center to diagnose and repair your smartphone.
- The smartphone overheats - for example, during high-cost operations: games or working with applications that load the processor. Therefore, you need to think about the health of the battery and other components involved in overheating.
- The smartphone has fallen - here you definitely need to contact specialists and do not rely on secret life hacks with your smartphone, this is unlikely to help.
- Factory defects - this option cannot be ruled out, since smartphones are produced in large quantities and the possibility of marriage increases.
So, analyze and try all the options that suit your case and device.
Even the most reliable equipment can suddenly fail, and Android devices (even from well-known brands) are no exception. One of the most common problems problem that occurs on phones running this OS is a constant reboot (bootloop). Let's try to figure out why this problem occurs and how to get rid of it.
There may be several reasons for this behavior. They depend on many circumstances that need to be taken into account: whether the smartphone has been subjected to mechanical damage, whether it has been in water, what type of SIM card is installed, as well as what software and firmware are installed inside. Let's look at the reasons for reboots.
Reason 1: Software conflict in the system
A headache for developers of Android applications and firmware is the huge number of device hardware combinations, which makes it impossible to test all existing ones. In turn, this increases the likelihood of conflicts between applications or components within the system itself, which causes a cyclic reboot, otherwise known as a bootloop. Also, bootloops can cause interference in the system by the user (incorrect installation of root, attempt to install an incompatible application, etc.). The best method To fix such a failure, reset the device settings to the factory state using recovery.
If this does not bring results, you can also try to reflash the device - yourself, or using the services of a service center.
Reason 2: Mechanical damage
A modern smartphone, being a complex device, is very sensitive to extreme mechanical stress - shocks, shocks and falls. In addition to purely aesthetic problems and damage to the display, this also affects motherboard and the elements located on it. It may even happen that the phone’s display remains intact after a fall, but the board is damaged. If, shortly before the reboots began, your device experienced a crash, this is most likely the reason. The solution to this kind of problem is obvious - a visit to the service.
Reason 3: Battery and/or power controller failure
If your smartphone is several years old and it starts to periodically reboot on its own, there is a high probability that the reason is a failed battery. As a rule, in addition to reboots, other troubles are observed - for example, rapid battery drain. In addition to the battery itself, problems with the operation of the power controller are also possible - mainly due to the above-mentioned mechanical damage or defects.
If the reason is in the battery itself, then replacing it will help. On devices with a removable battery, it is enough to buy a new one and replace it yourself, but devices with a non-separable case will most likely have to be taken to a service center. The latter is the only rescue measure in case of problems with the power controller.
Reason 4: Faulty SIM card or radio module
If the phone starts to reboot spontaneously after inserting a SIM card into it and turning it on, then this is most likely the reason. Despite its apparent simplicity, a SIM card is a rather complex electronic device that can also break. Everything is checked quite easily: just install another card, and if reboots do not occur with it, then the problem lies in the main SIM card. It can be replaced in the company store of your mobile operator.
On the other hand, this kind of “glitch” can also occur if there is a problem with the radio module. In turn, there can be a lot of reasons for this behavior: starting from manufacturing defects and ending with the same mechanical damage. Changing the network mode may help. This is done like this (note that you will have to act quickly in order to be in time before the next reboot).
Reason 5: The phone was in water
For any electronics, water is a mortal enemy: it oxidizes contacts, which is why even a phone that seems to have survived a swim fails over time. In this case, reboot is just one of many symptoms that usually accumulate on an increasing basis. Most likely, you will have to part with your drowned device: service centers may refuse to repair it if it turns out that the device has been in water. We recommend that you be more careful in future.
Reason 6: Bluetooth Problems
A rather rare, but still relevant bug in the operation of the Bluetooth module - when the device reboots, you just try to turn it on. There are two ways to solve this problem.
- Don't use Bluetooth at all. If you use accessories like a wireless headset, fitness bracelet or smart watch, then this solution is definitely not suitable for you.
- Reflashing the phone.
Reason 7: Problems with the SD card
Sudden reboots can also be caused by a failing memory card. As a rule, this problem is accompanied by others: media server errors, the inability to open files from this card, the appearance of “phantom” files. The best solution will replace the card, but you can first try to format it by first doing backup copy files.
Reason 8: Presence of a virus
And finally, the last answer to the question about rebooting is that a virus has entered your phone. Additional symptoms: one of the phone applications suddenly starts downloading something from the Internet, shortcuts or widgets appear on the desktop that you did not create, certain sensors turn on or off spontaneously. The simplest and at the same time radical solution to this problem would again be to reset to factory settings, the link to the article about which is presented above. An alternative to this method would be to try using an antivirus.
We got acquainted with the most typical causes of the reboot problem and options for solving it. There are others, but they are mostly specific to some specific model Android smartphone.
Telephones are devices that almost all citizens now have. Operating such a gadget is quite easy. But only from time to time various problems can happen to it. For example, what if your phone constantly reboots? Moreover, this happens spontaneously and without reason, as it seems to you. There are a lot of options for the development of events. What should you pay attention to first? How to correct the situation as soon as possible?
Software failure
So, the first and most common reason that the phone constantly reboots is a failure of the installed software. Or, as they also say, an operating system. As practice shows, very often malfunctions in the installed software cause problems with the performance of the device.
What to do in such a situation? First, try turning your phone off and on again - the software glitch may be fixed. As a result, the problem will disappear.
Secondly, flash the device. In this case, it is advisable to take the phone to specialized service centers. They will reinstall you there 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 will not be required. After all, there are many reasons why the phone constantly reboots.
Software
Does your phone constantly reboot? Think about what programs and applications you have installed recently. They may be the cause of this problem.
The thing is, sometimes it's wrong installed programs cause system failures. As a result, the phone begins to reboot. The only correct solution is to detect a “malicious” application and then remove it.
If you really need the program, try simply erasing it and reinstalling it. Same good way, but it does not provide any guarantee of success, please 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 problems.
Battery
Does your phone keep rebooting (Samsung or any other)? Don't be scared or 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 gadget's battery - this is a very important element for the functioning of the device. If something is wrong with it, the phone will begin to behave in unpredictable ways. As practice shows, when a battery malfunctions, the device usually either spontaneously reboots or turns off for no reason.
What to do in this case? If you are sure that the cause of the problem with the gadget is the battery, replace it. Just purchase new battery and insert it into the device. Charge the battery and see how the phone behaves. Most likely the problem will go away. No? This means that the reason for rebooting the smartphone was something else. What other options for the development of events take place?
Moisture
Does your Sony phone keep rebooting? Or any other smartphone, really? The reason for this may be moisture. In rooms with high humidity, gadgets can behave unpredictably. And if you recently got your phone wet, then there’s nothing surprising about the problem that has arisen! Why? Because the device, in principle, could not turn on. And a reboot in this case would not seem like a problem at all.
If you suspect that your smartphone is starting to restart due to increased humidity, just try to return to normal as quickly as possible. As soon as you leave a place with high humidity, the gadget will work normally.
Does your phone keep rebooting? What should I do if the cause is moisture getting on the device? There is only one way out - dry your smartphone as soon as possible. Take it apart. Next, dry all parts thoroughly with a towel or napkin. In some cases, you can use a hairdryer to quickly dry it. Once all the parts are 100% dry, reassemble the gadget and see if the problem is resolved. Usually, with prompt action, the result will not be long in coming. Nowadays, many phones tolerate moisture well. Therefore, there is no particular reason to panic.
Settings
Does your LG phone reboot constantly (or any other gadget model in general)? In this case, you should pay attention to the system settings of your device. They often cause many problems with smartphones. The phone may turn off, reboot, or slow down. All this points to broken settings.
You can edit them yourself so that the system does not reboot. This is difficult to do, so many people prefer a radical method - flashing. The most difficult and most effective process. It is not recommended to implement it yourself; seek help from specialists. If the reason for the constant reboots lay precisely in the broken settings, then after flashing this phenomenon will disappear.
Space
What else can you pay attention to when your phone keeps rebooting? On the amount of information on the gadget. Take a good look at how much space is left on both the memory card and the built-in storage space. For what?
The problem is that often full memory in any gadget leads to problems. Fortunately, the situation can be corrected easily and simply - just clean your smartphone. Remove all old and unnecessary applications, media files and programs. And get into the habit of cleaning your phone space from time to time. This way you can get your device back on track and prevent the problem from reoccurring.
By the way, if you are wondering why your phone keeps rebooting, look at the total capacity of your memory card, if you have one. Each smartphone works smoothly only with a certain amount of additional space. If a larger memory card is inserted into the gadget, performance is impaired. As a result, crashes, sudden reboots and shutdown of the gadget appear. Therefore, use only memory cards that meet the maximum capacity for your phone model.
Overheat
There is another not very dangerous and easily eliminated reason for a sudden reboot of a smartphone. In principle, the same option is relevant for other gadgets (like computers). We are talking about overheating. As soon as the device heats up to a certain temperature, it either turns off or reboots. This is a completely normal phenomenon - this is how the system protects itself from failure.
The solution to the problem is simple - just stop letting the device overheat. Turn off those running in background programs, do not use the phone continuously for too long. This is the only way you will be able to normalize the operation of the gadget. Try not to keep it in the sun.
Viruses
Does your phone constantly reboot? What to do in this case? Check it for viruses. Telephone infection often causes spontaneous reboot devices. A variety of antiviruses will help in this matter. Or service centers.
If you find viruses on your mobile phone, remove them. After treating the phone, all problems will disappear on their own. Viruses are found more and more often on smartphones every day. Therefore, this option is worth checking first.
Time
In some cases, if your phone keeps rebooting, you just need to change it. Each device has its own service life. And when it comes to an end, various failures and problems appear. There is no way to fix them. To avoid wasting time, take your phone to a service center - they will help you find the source of the problem and also tell you whether it makes sense to repair it.
Wear and tear of equipment is inevitable. So if your phone has been working for about 5 years and then suddenly starts rebooting, it is quite possible that it needs to be replaced.
