Let's look at the main reasons why the Android phone reboots by itself: what causes this and how this or that problem is fixed. Interestingly, both Chinese “NoName” brands and eminent flagships like samsung galaxy, HTC One, or Sony Xperia. Let's understand the reasons.
Mechanical damage
Let's start with the leader of all troubles - falls. This also includes blows, negligent use, use of a smartphone for other purposes (opening bottles, hammering nails, etc.). Kind of funny, but they happen all over the place. The phone is designed for calls and work, but not for such events. Yes, there are shock-resistant models produced by companies like CAT, but they are few and far between.
Methods of "treatment" are banal to disgrace: buy a cover, a bumper and protective glass. Protection is flimsy, but periodically saves. This will protect you from damage to the motherboard, processor blade, memory, camera module and vital cables. But it's still worth going to the service to understand exactly the reason for the reboots.
Firmware and all about them
Often heard from friends about "firmware"? In short, this is the replacement of the “native” smartphone OS with a more recent version, or a modified one. There are 3 options:
- official;
- custom;
- test.
If you start to slow down native firmware device (too many applications, not updated for a long time, viruses, residual files cache), then you can reset to factory settings– should help in 90% of cases. It is also worth looking on the Internet, which android version relevant for smartphone this moment. The update process happens on its own without your intervention, so no skills are required.
Custom ones are more difficult. The only stable foreign firmware can be considered exclusively Cyanogen Mod, but this team broke up, and the remnants of the team renamed themselves Lineage OS. Their work was really worthy, but had one significant disadvantage: The firmware was installed at your own peril and risk. Also be prepared for reboots, CPU overheating, unstable battery, GPS, modem and other key components that affect stability.
As for the test ones, which are laid out in abundance on resources like w3bsit3-dns.com, XDA and analogues. If you are going to use your smartphone as a “guinea pig” and know about the problems in advance, install it. The rest is categorically not recommended to do such things without knowledge of the materiel. This is the easiest way to turn the device into a "brick", not to mention the cyclic reboots.
Battery
The battery, like any storage device, is designed for a certain number of charge / discharge cycles. If you constantly charge the device, then sooner or later the battery will simply lose its full potential and will not hold a charge. A similar drawback is typical for Li-Pol models with a "memory effect". Ying must be charged to 100%, and then discharged to 0. Only after that you can put it on charge. Li-Ion drives are devoid of such a flaw.
Critical moment: it is necessary to use exclusively "native" Charger. The point is the current strength indicated on the charge. If the manufacturer indicated, for example, 1A (Amp), then the value cannot be exceeded. Therefore, do not use more powerful analogues at 1.5-2A, since you can “kill” the battery much faster. She's just pissed off. The average cycle with proper operation is limited to 1.5-2 years. In the future, the battery begins to lose its properties.
Another factor is contact oxidation. If moisture has accumulated inside the device, then this may be the reason for the reboot. If the battery is removable, remove it, dry the smartphone, wipe everything with alcohol pads as carefully as possible and insert the drive after 30-60 minutes. A swollen one must be replaced.
Motherboard defects and factory defects
This category is the most unstable due to the fact that there are many reasons for the breakdown of contacts, loops and other elements, only a complete analysis and verification of each component individually will help here. Often, a defect is caused by a fall, “curiosity” (opening a smartphone to see how everything works there and subsequent inaccurate assembly), moisture, dust, and more.
Less common is a factory defect, which affects no more than 1-2 gadgets per 100,000 devices. The manufacturer often indicates this himself. Also look at thematic forums, look for a topic with your model and see the characteristic "sores". If you didn’t drop, drown or open the device, and it reboots, then something is short inside. It is better to send such a smartphone under warranty. You will lose time, but you will get a workable analogue.
Memory problems
Installation a large number applications are highly discouraged due to conflict specific files between themselves. This is especially true for programs for working with the camera, GPS, data, antiviruses and "cleaners". Each has its own algorithm of work, so reboots are not uncommon.
First, leave only 1 option certain applications. Extra cost format SD card if files were placed on it. Don't forget about
Android phone keeps restarting
What to do if your Android phone keeps restarting
Unauthorized reboot of a smartphone on Android is usually associated with unstable job any application on the device. There is one factor that affects the operation of a smartphone: if you download and install applications a lot and then delete them and then do the same, then after a while you will notice that Android does not work so fast, and sometimes it starts to “freeze”. If you practice this the best way out will be a smartphone.
It is best, of course, to download exactly those applications that have already been tested. good popularity and high rating.
The question arises why the smartphone freezes or reboots after deleting applications. AT Google Play a very immeasurable number of applications, 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 bunch of garbage after deletion, thereby causing crashes and reboots.
If, after installing the application, the smartphone starts rebooting, this should alert you. It is better to remove such an application immediately, and make sure that everything system folders have also been removed from the device.
Another option for checking this is the Device, read our article for more details on how to do this.
Android constantly reboots - it's worth checking for a virus
One of the obvious options for why the smartphone reboots is the infection of the device with viruses and all sorts of malware. In order to check your phone for a virus, use applications that analyze the entire system.

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 all the same, the reason is the memory card. Transfer data (photos, videos and other data) to a PC and format the card. For more information on how to disable an SD card and format it, we wrote in
Even the most reliable technology can suddenly fail, and Android devices (even from famous brands) - not an exception. One of the most common problems that occurs on phones running this OS is a permanent 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 mechanically damaged, whether it has been in water, what type of SIM card is installed, and what software and firmware are installed inside. Consider the reasons for reboots.
Reason 1: Software conflict in the system
A headache for developers of applications and firmware for Android is great amount hardware combinations of devices, which makes it impossible to test all existing ones. In turn, this increases the likelihood of application or component conflicts within the system itself, causing cyclic reboot, otherwise bootloop (bootloop). Bootloops can also cause user intervention in the system ( incorrect installation root trying to install incompatible application, etc.). best method to fix such a failure will be resetting the device to the factory state using the recovery.
If this did not bring results, you can also try - on your own, or using the services of a service center.
Reason 2: Mechanical damage
The modern smartphone is complex device, is very sensitive to extreme mechanical loads - shocks, shocks and falls. In addition to purely aesthetic problems and damage to the display, the motherboard and the elements on it. It may even happen that the display of the phone remains intact after the fall, but the board is damaged. If shortly before the appearance of reboots, your device survived a fall, this is most likely the reason. The solution to this kind of problem is obvious - a visit to the service.
Reason 3: Faulty battery and/or power controller
If your smartphone is already several years old, and it has begun to periodically reboot on its own - Great chance that the cause is a failed battery. As a rule, in addition to reboots, there are other troubles - for example,. In addition to the battery itself, there may also be problems in the operation of the power controller - mainly due to the mechanical damage or marriage mentioned above.
If the cause 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 carried to the service. The latter is the only measure of salvation in case of problems with the power controller.
Reason 4: Faulty SIM card or radio module
If the phone starts to spontaneously reboot after the SIM card is inserted into it and turned on, then this is most likely the reason. Despite its apparent simplicity, the SIM card is quite complex. electronic device, which can also break. Everything is checked quite easily: just install another card, and if there are no reboots 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 the radio module malfunctions. In turn, there can be a lot of reasons for such behavior: starting from factory defects and ending with the same mechanical damage. Changing the network mode may help. It 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 has been in water
For any electronics, water is a mortal enemy: it oxidizes contacts, which is why even a seemingly surviving phone after bathing fails over time. In this case, the reboot is just one of many symptoms that usually accumulate on the rise. Most likely, you will have to part with the “drowned” device: service centers may refuse to repair if it turns out that the device has been in the water. We recommend that you be more careful in the 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 have to try to turn it on. There are two ways to solve this problem.
- Don't use Bluetooth at all. If you are using accessories like wireless headset, fitness bracelet or smart watch, then this solution is definitely not suitable for you.
- Phone flashing.
Reason 7: Problems with the SD card
The reason for sudden reboots can also be 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 files.
Reason 8: Presence of a virus
And finally, the last answer to the question about rebooting is that a virus has settled in your phone. Additional symptoms: some of the phone's applications suddenly start downloading something from the Internet, shortcuts or widgets that you did not create appear on the desktop, certain sensors turn on or off spontaneously. The simplest and at the same time radical solution to this problem will again be reset to factory settings, the link to the article about which is presented above. An alternative to this method would be to try .
We got to know the most characteristic reasons reboot problems and solutions. There are others, but they are mostly specific to some specific model Android smartphone.
Now we will look at the main reasons why ZTE phone reboots by itself and what to do in such a situation.
Very often, gadget owners mistakenly mean by this term a constant (cyclic) reboot of the device, as a result of which the phone turns off and on constantly. These are different symptoms and we will still focus on the situation when it reboots itself during operation with some interval (1-3-10-60 minutes and the like).
There can be many reasons for an arbitrary reboot, both from the side of the firmware and installed apps, as well as with the hardware. Accurate diagnosis requires not only special equipment, but also the experience of repairing modern smartphones.
Reasons why ZTE reboots by itself
Now let's look at the main reasons for this behavior of the phone and what measures can be taken.
Firmware issues
This problem is the main one. Firmware flaws can lead to shutdown, reboot and braking of the device during operation. The solution to the problem is flashing, reinstalling the system with latest updates. It is not recommended to do this on your own, because. you can delete important data.
Very often, users encounter this when it comes out. a new version Android or ZTE itself releases "fractional" firmware versions (7.0.1 for example). Alternatively, rollback to the previous stable version if you have a backup.
Battery problems
It happens that ZTE reboots by itself due to battery problems. She may simply lose contacts during "shaking", i.e. everyday use. Here it is necessary to check the tightness of the battery to the contact group and the performance of the battery itself. All this will help to understand the diagnosis performed by a professional.
Mechanical damage to parts
In case of impact or moisture getting under the case, any element can fail. Even a minor crack in one of the many cables inside a smartphone can close the circuit, causing the system to reboot as insurance.
It is problematic to determine this "by eye" and you need to disassemble the smartphone, for which a special tool is used. Let's not forget that modern phones very complex architecture internal structure and you will need experience in such work so as not to damage other modules.
Liquid ingress
The liquid has a destructive effect on the performance of the device. Oxidation and decay of parts leads to full performance. And rebooting the device can be one of the main signs. The smartphone must be brought to service center so that the master can dry and restore damaged areas.
Manufacturing defects
If the smartphone turns on and reboots, it may be a factory defect. If it is not possible to replace the device under warranty, bring it to us, and the master will repair it with the replacement of the required parts.
Solution
Contacting our service center will help you get rid of any problems. This is done as follows:
- Bring your smartphone to our workshop;
- The engineer will determine the cause of the problem on the diagnostics, which will take from 5 minutes;
- The cost of services will be named, after agreement we will get to work;
- We'll get to work, maybe urgent repair on the day of application.
Contact us and soon you will receive a fully working ZTE.

Good afternoon. I have the same question for you as many people. A question about spontaneously rebooting a ZTE brand phone. Rebooting the device does not often, maybe once every two days. But there is little pleasant in this. I understand that in any case I will have to come to your center. I myself am from Moscow. Could you write the address of the center and its Contact phone numbers. Thank you in advance....
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. Amplifier replacement or battery is carried out quickly and does not hit the budget of the owner of the smartphone 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 adversely affect the condition mobile device: The phone does not turn on or constantly restarts.
Troubleshooting
Try to determine at what point the phone reboots - this will help you quickly diagnose the cause and fix the problem. Everything depends on it further actions 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'll have to purchase 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 that doesn't help, get on with it. software phone - update the system yourself or contact the service center.
When turned on
If the phone restarts immediately after turning it on, try applying following methods troubleshooting:
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 restarts when incoming call or right during a conversation, then the most probable cause is the loss of battery contact with 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 apps are blocked after update normal work mobile device or start 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 scan did not reveal anything suspicious, then make copies of all important files and return the phone to default 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 you turn on the camera may be mechanical damage: for example, after the impact, the plume departed. 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 restarts due to Bluetooth modules or GPS. 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.
