Constantly and unscheduled reboot of your Android smartphone is an annoying error. It generates a bad mood and a desire to part with the gadget. A quick and effective solution in this case is a visit to a repair shop with free diagnostics. But there is not always time for this, so first we will try to fix the problems ourselves.
Quick methods to fix erroneous reboot
It often happens that the phone reboots while charging. In this case, we recommend using the "native" charger. Another type of failure is rebooting after installing / replacing a SIM or SD card. They need to be changed and / or flashed (updated) Android OS.
It so happens that turning off / on occurs in the cold - this is a short-term phenomenon. After moving to a warm room, everything falls into place.
Another type of problem is disconnecting and returning to the previous state during a call or conversation. In this case, you can try disabling the 3G network, resetting the settings or changing the SIM card, especially if it is in Micro-SIM or Nano-SIM format.
Why does the phone restart itself?
There are many reasons for a sudden restart:
- viruses,
- mechanical damage,
- software failure,
- iron problems,
- sticking of the power key due to improper operation of the device.
Before taking serious steps - do the simpler ones, such as checking for viruses or replacing the battery.
Note! If the power key is stuck (this is possible if you constantly pressed it with wet or sweaty hands), wipe it and the contacts of the charger switch with a nail polish remover without acetone, or better, soak them for 20-30 minutes in the solution.
How to fix reboot problems
Let's take a look at how to fix common problems that cause your phone to restart. You can do them yourself.
Infection with viruses
A smartphone is no longer just a device for communication and entertainment, but also a real “bank in your pocket”. It can be used to pay for purchases, perform transactions with cards and accounts, etc. It is not surprising that fraudsters regularly come up with new ways to steal information.
So, to check for viruses:
Kaspersky Internet Security has a good reputation, so let's look at the process based on this antivirus.
The battery is discharging
A battery cannot last forever. Over time or from improper operation, its resource is depleted, after which it must be changed.
Battery replacement
The battery can be easily replaced if it is removable. Buy a new one and swap with the old places, and first check the tightness (poor contact) and carry out a visual inspection for deformations.
If the battery cannot be removed, send it for repair for replacement or, if the warranty service has not yet expired, to a specialized center where the battery will be replaced free of charge.
Battery Calibration
It is not always necessary to change the battery right away if the phone reboots by itself. Sometimes it makes sense to calibrate it. For this:
- Discharge the phone to zero, then turn it on again and wait until it turns off;
- Insert the charger into the socket and leave the smartphone until fully charged (do not turn it on);
- Disconnect charging and turn on your phone. If the charge is not enough, plug it back in and bring the level to 100%;
- Unplug the charger and restart the device. If the charge is again insufficient, reconnect the phone to the network. Do this until the charge level reaches 100%;
- Repeat steps 1 and 2.
Failed software update
The phone often restarts due to a software malfunction. To fix the problem, you can return your smartphone to factory settings or update the firmware.
Installing the update
Reset
The settings are reset as follows:
Mechanical damage
A constant reboot could appear after a blow if you dropped the phone / hit classmates with it / used it as a throwing projectile. Damage to the printed circuit board can result. A complete replacement of the part or soldering of its elements will be required.
If the above methods did not correct the situation, there is a possibility that mechanical damage is the cause of the constant reboot. Here there is only one option - to take the mobile phone for repair.
By the way, the reason why the phone is constantly rebooting may be a factory defect. You have the right to terminate the sales contract and return the money or demand replacement of the product for a similar one. In any case, the decision will be made after the examination. In the meantime, it is being done - read the law "On Protection of Consumer Rights", specifically - the section on the return of technically complex goods.
In the article, we will consider the reasons why the android itself reboots, their solutions. Let's take simple steps that in some cases can save you from going to the service center, which means they will save time and money. This breakdown is typical for famous and unknown brands, as well as old phones. The reasons for the spontaneous reboot of Android can sometimes be fixed at home, but some can only be dealt with in the service center, if the phone or tablet can still be saved.
Reasons related to smartphone battery:
- Poor battery contact or oxidation;
- The battery does not correctly distribute signals to the modules;
- A swollen or otherwise mechanically damaged battery;
- Damaged power charging controller due to using non-original or cheap charger;
- The battery has served its purpose;
- Poor quality of non-original battery;
- Ingress of moisture and dirt under the housing.
Only changing the battery to another will help, since they are not repaired.
Other technical reasons:
- Breakdown of the signal power accelerator;
- Sagging power button;
- 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 relevant if a custom, unsuitable, beta version of the OS is manually installed or the release has occurred recently);
- Overheating of the smartphone;
- Virus on the device.
This is why the phone itself restarts android.
What to do if your Android phone is constantly rebooting. Application problems
Do you have multiple antiviruses, cleaners, camera apps, GPS? Algorithm conflict possible. Therefore, do not install too many programs, especially if you are not sure that you need them. Start in Safe Mode. If the restarts stop, uninstall unnecessary applications. Check your device for viruses. Have you noticed overheating and long reaction times of your smartphone? Perhaps you downloaded something from unverified sources. More specifically, the presence of a virus is indicated by restarting the phone when starting an application (for example, a camera). The highest quality antivirus 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 tired of notifications about the lack of memory? Try to clear the program cache ("Settings" - "Applications" - any application from the list - "Clear cache"), delete unnecessary ones. You can use one of the cleaning programs: Clean Master (if there is an antivirus, it may conflict), DU Speed \u200b\u200bBooster & Cleaner, GO Speed.
If you suspect a malfunction of the OS
If you think that there is nothing suspicious and new in your files, and the previous tips did not help, reset the settings to the factory settings, after saving important data on an external drive (a flash drive is suitable), reset the settings to the factory settings. This advice is suitable when it was not possible to identify the problematic software on its own or there is suspicion of damage to system files. Section "Settings" - "System" - "About phone" - "Software update". Why does the phone keep restarting on its own android? There may be a problem with the firmware. To update it, go to "Settings" - "About device" - "System updates" - click "Check now". Agree to a software update. The smartphone will reboot itself after the operation is complete. If there are no updates, look for information about your smartphone model along with the Android version. Perhaps the problem is with the firmware. You will have to wait until they fix it or find an unofficial version to install if you are sure of your actions. Reboots while turning on the bluetooth. Change your phone's firmware. If it reboots too quickly for this, pull out 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 face this anymore. If you need and want, you can install a third-party file transfer application.
Actions in case of physical damage to the device
In case of technical damage, most likely, you need to contact the service center for help. You can still try to do something yourself. There may be a problem with the memory card. Take it out and perform the action that usually provokes a reboot. If not, format the memory card. Did not help? Change to a new one if possible. Remove the battery and wait 30 minutes. This will help prevent overheating that could be causing the restarts. Android phone keeps restarting Android when shaken. In this case, the battery loses contact with the contacts. This can happen if the phone is used frequently. You need to re-solder the contacts. Of course, it is better to do this in the service, but you can do it yourself. Soldering is a rather delicate process that should be considered separately. Seeing contamination on the battery terminals? Remove the battery, wipe the connections with cotton wool soaked in contact cleaner or sprinkle. Bend the contacts slightly to make a tighter connection with the battery terminals. Does the phone reboot after turning on GPS and can't start? There are several solutions. Replace the SIM card if it is much older than the smartphone.
The case may be in the memory card or settings that need to be rolled back to the factory settings.
The Samsung phone restarts itself. In addition to Android, Samsung smartphones were released under Windows Phone. For the former, the problem of spontaneous reboots is more common. Solution options, as in the previous paragraphs. To roll back the firmware if necessary, visit the manufacturer's official website: http://samsung-updates.com/device/
Android phone constantly reboots
What to do if your Android phone is constantly rebooting
Unauthorized reboot of a smartphone on Android is usually associated with the unstable operation of an application on the device. There is one factor affecting the operation of the smartphone: if you download and install a lot of applications and then uninstall 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 solution would be a smartphone.
It is best, of course, to download exactly those applications that have already been tested have good popularity and a high rating.
The question arises why the smartphone freezes or restarts after uninstalling applications. On Google Play, there is a very immense number of applications, some are "completely safe" - they do not affect the robot's device in any way, while others may 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 uninstall such an application immediately, and make sure that all system folders have also been removed from the device.

Android keeps rebooting - it's worth checking for viruses
One of the obvious options why the smartphone is rebooting is infecting the device with viruses and all sorts of malicious programs. In order to check your phone for a virus, use applications that analyze the entire system.

Frequent reboot of the smartphone as a result of a hardware failure
The reasons why you will have to contact the 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 fell - here you definitely need to contact the specialists and do not rely on secret life hacks with the smartphone, this will hardly help.
- Factory marriage - this option cannot be ruled out as smartphones are produced in large quantities and the possibility of marriage increases.
So analyze and try all the options that fit your case and device.
Reading time: 4 minutes
Let's look at the main reasons why the Android phone reboots by itself: what causes this and how this or that problem is eliminated.
Interestingly, both the Chinese "NoName" brands and the famous flagships like Samsung Galaxy, HTC One, or Sony Xperia are subject to the disadvantage. Let's understand the reasons.
Mechanical damage
Let's start with the leader of all troubles - falls. This also includes blows, negligent use, misuse of the smartphone (opening bottles, hammering nails, etc.). It looks like funny cases, but they happen everywhere. The phone is made for calls and work, but not for such events. Yes, there are shockproof models made by companies like CAT, but only a few.
Methods of "treatment" are banal to disgrace: buy a cover, bumper and protective glass. Protection is flimsy, but periodically saves. This will save you from damaging the motherboard, processor blade, memory, camera module and vital cables. But it is still worth going to the service to understand exactly the reason for the reboots.
Firmware and everything about them
Have you 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 the native firmware of the device starts to slow down (there are too many applications, have not been updated for a long time, viruses, residual cache files), then you can reset the settings to the factory settings - it should help in 90% of cases. It is also worth looking at the Internet, which version of Android is relevant for the smartphone at the moment. The update process takes place on its own without your intervention, so no skills are required.
It's more difficult with custom ones. The only stable foreign firmware can be considered exclusively Cyanogen Mod, but this team disintegrated, and the rest of the team renamed themselves Lineage OS. Their work was really decent, but had one significant drawback: 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 affecting 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 "test subject" and you know about the problems in advance - install. The rest is strongly discouraged from doing such things without knowing the materiel. This is the easiest way to brick your device, not to mention 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 disadvantage is typical for Li-Pol models with a "memory effect". Ying must be charged to 100%, and then discharged to 0. Only then can you put on charge. Li-Ion drives are devoid of this flaw.
Critical point: you must use only the "native" charger. The point is in the amperage indicated on the charge. If the manufacturer has indicated, for example, 1A (Ampere), then the value cannot be exceeded. Therefore, you should not use more powerful analogs of 1.5-2A, since the battery can be “killed” much faster. It will simply swell. 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 restart. If the battery is removable, remove it, dry the smartphone, wipe all contact pads with alcohol as gently as possible and insert the drive after 30-60 minutes. The bloated 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 breakage of contacts, loops and other elements, only a complete analysis and verification of each component individually will help here. Often, the 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 often, a factory defect occurs, 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 typical "sores". If you did not drop, drown or open the device, but it reboots, then something is short inside. Better to send such a smartphone under warranty. You will lose time, but get a workable analog.
Memory problems
Installing a large number of applications is highly discouraged due to conflicts between certain files. This is especially true for programs for working with a camera, GPS, data, antiviruses and "cleaners". Each has its own algorithm of work, so reboots are frequent.
