Why the phone BQ 5520 reboots itself. Causes of the constant reboot of the smartphone. There are several solution solutions

A constant reboot is a fairly frequent problem of modern smartphones, especially noticeable in the cold season. Devices are simply not intended for operation at minus temperature. Note that supercooling is far from the only cause of infinite or frequent "resellers". The source of the problem can be both a decline of the device and software malfunctions. It is described below what to do if the phone itself reboots without stopping.

You can select several basic causes of frequent reboots.

Mechanical impact on the smartphone housing - a drop or a strong blow.
Failures in work operating system. This includes errors after installing incompatible firmware and updates and a malfunction of certain programs.
Failure or significant loss of battery capacity. The situation is relevant both for old devices and for new ones - but with poor-quality batteries.
Malfunction of motherboard modules responsible for power supply.
Fluid getting into the body of the phone, the oxidation of the elements and the appearance of rust.
Supercooling or overheating.

Problems can be caused by both software and hardware faults. Mechanical damage displays the components of the device, causing frequent rents.

Unsuitable battery - one of the main causes of such a defect. To check the battery, pull it out of the smartphone and carefully inspect. If convexity or visible damage are noticeable on the surface - the battery should be recycled and replaced with a new one. The discarded batteries are not subject to repair, but in some cases their life time can be extended:

Using a flat screwdriver, separate the sticker from the front part of the battery. Disconnect the chip and set aside, but do not open the controller contacts.
With the help of a thin needle, gently push the battery with the side part, where the controller board used to be.
Press the battery with a heavy object exceeding its housing over the area. Release the accumulated gas, but do not damage the battery.

Important! The above method will help extend the battery life for several days, but the replacement of the ACB should be carried out as soon as possible.

If the problem was in a faulty battery - reboot will stop for some time. Fully eliminate the defect is capable only by replacing the battery.

Phone reboots when starting android

If the gadget is rebooted each time the methods can help the following methods.

Complete the full reset via Recovery. On models of different manufacturers, the entrance to the recovery is slightly different. Universal method - When you turn on the phone, clamp the "volume down" buttons and blocking when the Android icon appears - release the loudness. Navigating the menu using the volume switches and power button. Select "WIPE DATA / FACTORY RESET", then confirm the selected action. Restart the device "Reboot System Now" team - the problem will disappear if the endless reset is caused by the wrong firmware.
Disconnect the battery and leave the device for 20-30 minutes in the off state. Then insert the battery back - in some situations, the method can help.

Important! After complete reset, all your data, accounts, photos and other personal information will be deleted. Conduce the procedure if the gadget is rebooted due to errors when firmware or update.

When you turn on the camera

The camera app is becoming a reboot on old iPhone after iOS updates before latest versionand in the case of infection with viral software. Check the device with antivirus or roll back to previous version Systems to eliminate faults.

After activating GPS.

Some Android smartphones can reboot when the system is turned on gPS navigation. The main problems and solutions of this defect are described below.

Old SIM - Map: Some smartphone models are incompatible with SIM cards of operators. Try replacing the SIM card to a new one or contact service center mobile communication provider.
Memory Card: SD - Map can also cause reset when including GPS.. Remove the memory media from the phone and check whether the malfunction disappeared.
Incorrect operation when firmware: Perform a hard reset if the gadget is rebooted after installing the modified version of the OS. How to perform the procedure described in the picture.

When you turn on Bluetooth

Instant response after activating the file transfer function - a frequent problem of HTC models.

Eliminate malfunction can be executed Hard Reset.But in this case, your information and accounts will be deleted.
Bluetooth usually takes a few seconds for switching on - try disable the function when the device is restarted. Access to the option is possible through the "cortex" of notifications - as soon as Android and the main menu is loaded, disable the multimedia data transmission.

When talking

If the gadget performs a reset when talking, check the battery contact with the main board. Perhaps, after a long operation between the battery and the connector, the gap appeared, eliminate which can be fixed by the battery for double-sided tape.

When starting applications

Some programs cause android reboot due to bad optimization or errors during execution. The simplest and effective solution is to remove the "problem" application. Perhaps the problem is not in the program itself, but in certain drivers or wrong work OS. In this case, a complete reset of settings will help.

When connecting to PC

If, after connecting to the computer, the gadget is restarted, make sure that the following problems are missing:

The USB cable is connected correctly, and the cord does not have physical damage.
Android-phone or Windows PCs are not infected with malicious software.
On the computer installed compatible drivers. If for some reason the utilities required for the work are not loaded, download them manually from the manufacturer's website.

Conclusion

Android I. IOS smartphones Can restart in different reasons. In some situations, the fault is caused by incorrect firmware or applications, in other - physical damage to the device body. Repair of the program part can be performed at home, but in other cases it is advisable to contact the manufacturer's service center.

Video

Smartphone or tablet can reboot yourself for several reasons. Check out the recommendation queue for each of them.

One-time program failure

Do not worry if the device is rebooted rarely - once a week or two.

First, it may be due to the accidental press of the "Power" button. If you keep it pressed for a few seconds, then the device
reboots.

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

Ubank application

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

If the device stopped independently rebooted, the problem is in the application. Try to enable it later if you need it.

If the device continues to restart after turning off Ubank or you do not have such an application, go to the next recommendation.

If the device restarts once a week in strictly a certain timeIt is possible that the "Automatic Reload" function is enabled. Check it out: Menu - Settings - General settings - Reset - the automatic reboot must be turned off.

If a automatic reset It was turned off or it did not help, go to the next recommendation.

Influence of installed applications

The device can reboot due to applications that were installed after purchase. Some of installed applications "Freezes" and stops the operation of the operating system. To reset this "error" device reboots.

Check if the installed applications affect the device, downloading the device in safe mode. In this mode, all downloaded applications are disconnected and only those that were installed at the factory work.

If the device is working normally in safe mode, some kind of loaded application is guilty. Unfortunately, there is no possibility to determine which one, so we recommend deleting one by one, starting from the last or updated one. After deleting the application, watch the operation of the device. If the problem has disappeared, it was in remote application. If it did not disappear - it was not in it, delete the following.

If the device still restarts in safe mode, go to the next recommendation.

Some users face an unpleasant situation - their phone is constantly rebooted, which prevents the execution of any tasks on the mobile device. A reboot can occur at different stages: when you turn 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 is constantly rebooted, and how to eliminate this problem.

Causes of reboot

Sometimes, as a result of the software failure, users have to restart the phone. But if the device is restarted independently, it does it for one of the reasons listed below:

Fitting a battery or signal power amplifier.
Serious software failure.
Mechanical damage.
Impact of moisture.

Most often, users faced with the failure of the signal power amplifier, which leads to an increase in energy consumption and subsequent emergency reboot. Replacing the amplifier or rechargeable battery It is carried out quickly and does not hit the budget of the owner of the smartphone.

In second place in "popularity" - a software failure. The cause of its appearance may be a conflict of devices and installed applications or user errors when flashing.

Mechanical damage or impact of moisture also negatively affect the state mobile device: The phone does not turn on or constantly reboots.

Troubleshooting

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

Restarts all the time

If the phone restarts constantly, then check the battery first - it may be out of order. Pull out the battery, put it on the table and try twist.

If, after a small push, the battery is spinning for a long time on the table, then it has bulges, that is, swells. In the normal state, the battery will not spin - stop almost immediately after the shock.

Swollen batteries are not repaired, so you will have to purchase new battery. But after installing it, the problem with the reboot must be successfully resolved.

If the problem is not in the battery, then try updating all applications and software. Start with applications: If there are updates for them, install them. If this did not help, do it software Phone - Update the system yourself or contact the service center.

When turned on

If the phone is restarted immediately after switching on, try applying the following troubleshooting methods:

Sometimes the phone is rebooted due to overheating or blown the "POWER" buttons. If none of the listed reasons suits you, you can try to reflash the smartphone.

During the conversation

If the smartphone reboots when incoming call Or right during the conversation, then the most likely reason is the loss of battery contact with the mobile device. It is possible to explain this by the appearance of a small gap between the connecting elements as a result of long-term operation or mechanical exposure.

To make sure that the reboot is the loss of contact between the battery and the phone itself, shake the device several times. If it turns off or restarts, contact the service center or refresh contact yourself.

Reset to system parameters.
Update firmware.

If the above methods did not help, then for the salvation of the phone will have to contact the service center.

After update

If you have installed updates, but the phone instead of starting to work better, is now constantly restarted, then try to start pulling the battery and install it in 15-30 minutes.

Some applications after the update block the normal operation of the mobile device or begin to conflict with each other.

If you do not notice any problems with the phone before the update, then try to roll back to the factory state - it should help solve the problem.

The cause of a permanent restart may also be malicious software. If a virus got on the smartphone, clean it with an antivirus system or reset the settings to the factory status and reflash the device. By the way, if the phone is rebooted when connected to a computer, here you also need to think about checking both devices for infecting viruses.

When starting applications or modules

Another common problem - the phone is rebooted when you start modules or individual applications. For example, the iPhone is restarted when the camera is turned on - the reason for this problem is often lifted in the viral infection.

If the test of antivirus 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 not unlikely to correct errors on the memory card or replace it at all.

The reason for the reboot when the camera is turned on may be mechanical damage: for example, after hitting the loop. You can eliminate this problem independently, but if you do not have enough knowledge, it is better not to open the body of the mobile device.

GPS and Bluetooth

Sometimes the phone is rebooted due to Bluetooth modules or GPS. Options for solving the problem here are a bit:

To eliminate the problem will also help flashing - the main thing is to carry it out correctly, without allowing any errors.

Applications

Often, the smartphone is restarted when you enable any application. To eliminate this unpleasant situation, try the following:

Make sure the battery is in order (not swollen, not drowsing, etc.).
Pull out the battery, wait 15-20 minutes and install it back.
Repress your mobile device.

To avoid conflict of equipment and applications, use the following recommendations:

Do not use the programs that clean the registry on the phone.
Do not load excessive "heavy" applications so that the smartphone does not work at the limit of technical capabilities.
Use official software, without cracks, assemblies and home releases.

If you reveal and eliminate the cause of the reboot is not possible, do not pull with contact with the service center: the phone repair is usually much cheaper than the new apparatus.

Even the most reliable technique can suddenly fail, and Android devices (even from well-known brands) is no exception. One of the most frequent problemswhich occurs on phones running this OS - constant reboot (bootlooop). Let's try to figure out why this problem arises and how to get rid of it.

The reasons for such behavior may be several. They depend on the set of circumstances that need to be considered: a smartphone has been subjected to mechanical damage, whether it visited water, which type of SIM card is installed, as well as what software and firmware are installed inside. Consider the reasons for reboots.

Cause 1: Software conflict in the system

Headache for Android application developers and firmware is great amount combinations of "iron" devices, because of which it is impossible to test all existing. In turn, it increases the likelihood of conflicts of applications or components within the system itself, which causes cyclic rebootOtherwise, Bootlup (Bootlooop). Also, the bootlup can cause interference with the system from the user (incorrect installation of the root, an attempt to establish an incompatible application, etc.). The best method Fix this failure will reset the device settings to the factory state using the recovery.

If the result did not bring it, you can also try to reflash the device - independently, or using the services of the service center.

Reason 2: Mechanical Damage

A modern smartphone, being a complex device, is very sensitive to extreme mechanical loads - shocks, concussions and drops. In addition to purely aesthetic problems and dispute damage, it suffers from this motherboard And the elements located on it. It may even happen such that the display of the phone after the fall remains the whole, but the board turns out to be damaged. If shortly before the start of rebooting, your device survived the fall - most likely the reason exactly in this. The solution to this kind of problem is obvious - a visit to the service.

Cause 3: Battery and / or Power Controller Fault

If your smartphone has been for several years already, and it started periodically rebooted on my own - the high probability that the reason is in the outfit battery. As a rule, in addition to reboots, other troubles are observed - for example, a quick battery discharge. In addition to directly the battery, problems are also possible in the operation of the power controller - mainly due to the mechanical damage or marriage mentioned above.

If the reason is in the battery itself, it will help his replacement. On devices with a removable battery, it is enough to buy a new one and replace yourself, but the devices with an unclear body will most likely have to be in service. The latter is the only measure of salvation and in case of problems with the power controller.

Cause 4: Faulty SIM-card or Radio Module

If the phone begins to spontaneously reboot after the SIM card in it and turned on, then it is likely that it is precisely in this. Despite the seeming simplicity, the SIM card is quite complicated electronic devicewhich can also break. It is all checked quite easily: just install another card, and if the reboot does not happen to it, then the problem lies in the main SIM card. It can be replaced in the corporate store of your cellular operator.

On the other hand, this kind of "glitch" may occur during malfunctions in the work of the radio module. In turn, the causes of such behavior may be mass: ranging from factory marriage and ending with mechanical damage. You can help changing the network mode. This is done like this (keep in mind that there will be quick to act quickly to catch up to another reboot).

Cause 5: The phone visited the water

For any electronics, water is a deadly enemy: it oxidizes the contacts, because of what even seemingly, the phone survived after bathing over time fails. In this case, the reboot is only one of the many symptoms, which usually dump on the growing. Most likely, you will have to break up with the "Drill" device: in service centers may refuse to repair, if you find out that the device visited water. It is also recommended to be attentive.

Cause 6: Bluetooth faults

Rather rare, but still current bug in work module Bluetooth - When the device restarts, you should only try to turn it on. Ways to solve such a problem there are two.

Do not use Bluetooth at all. If you use accessories like wireless headset, fitness bracelet or "smart" clock, then this solution is not exactly suitable for you.
Refracting the phone.

Cause 7: SD card problems

The reason for sudden reboots can be the faulting card of memory. As a rule, others are accompanied by others: media server errors, the inability to open files from this card, the appearance of files "phantoms". Better decision will replace the map, but you can first try to format it before backup files.

Cause 8: Presence of Virus

And finally, the last answer to the question of rebooting - the virus settled in your phone. Additional symptoms: some of the phone applications starts suddenly to download something from the Internet, there are shortcuts or widgets that you did not create, these or other sensors are switched on or off. The simplest and at the same time, the radical decision of this problem will be again reset to the factory settings, the reference to the article about which is presented above. An alternative to this method will try to use antivirus.

We got acquainted with the most characteristic reasons for the problem of rebooting and the options for its solution. There are other, but they are mostly specific for some specific model Android smartphone.

In the article, we will look at the reasons why android reboots themselves, their solutions. We will enter simple actions that in some cases can save from the campaign to the service center, and therefore save time and money. This breakdown is characteristic of eminent and unknown brands, as well as old phones. Android spontaneous reasons can sometimes be fixed at home, but they will only cope with some service center if the phone or tablet is still possible to save.

The reasons associated with the battery of the smartphone:

Weak battery contact or their oxidation;
The battery incorrectly distributes signals by modules;
Swollen or otherwise mechanically damaged battery;
Damaged power charging controller due to the use of a non-original or cheap charger;
The battery served her;
Low quality non-original battery;
Hit down the moisture body, dirt.

It will help only changing the battery to another, as they will not be revealed.

Other technical reasons:

Breakdown of signal power accelerator;
Foreign power button;
Damage to basic or pCB, other spare parts (after wetting, falling).

Software reasons:

The presence of applications that conflict among themselves;
The problems of the firmware (especially relevant, if manually installed custom, unsuitable, beta version of the OS or release occurred recently);
Overheating smartphone;
Virus on the device.

That is why the phone itself reboots android.

What to do if the android phone is constantly rebooted. Problems with applications

Do you have several antiviruses, cleaners, application applications, GPS? Conflict of algorithms is possible. Therefore, you should not install too many programs, especially if you are not sure what you need them. Run in safe mode. If reboots stopped, delete an excess application. Check the device for viruses. Have overheating and long smartphone reaction? You may have downloaded something from unverified sources. Specificable for the presence of a virus, the phone is rebooted when you start some application (for example, cameras). The highest quality antiviruses for Android: Norton Security & Antivirus, Sophos Antivirus & Security, Bitdefender Mobile Security & AntiVirus, Antiy Avl, Cheetah CM Security. No malicious software? You have a lot of "heavy" applications that often work simultaneously, and notifications about the missing amount of memory are already tired? Try to clean the cache of programs ("Settings" - "Applications" - any application from the list - "Clear Cache"), delete too much. You can use one of the cleansing programs: Clean Master (if there is antivirus, can conflict), du Speed \u200b\u200bBooster. & Cleaner, Go Speed.

In suspected OS malfunction

If you think that in your files, there is nothing suspicious and new, and previous tips did not help, reset the settings to factory, pre-maintaining important data on external accumulator (Flash drive is suitable), reset the settings to the factory. The Council is suitable when it was not possible to determine the problematic on its own or there is a suspicion of damage system files. Section "Settings" - "System" - "On the phone" - "Update software". Why is the phone constantly reboots in itself android? Perhaps there are problems in the firmware. To update it, go to "Settings" - "About Device" - "System Updates" - click "Check Now". Considerate the software update. Smartphone will reboot after the operation is completed. If there are no updates, look for information about your smartphone model along with the version of Android. Perhaps the problem is in the firmware. You will have to wait until you fix it or find the unofficial version, if you are confident in your actions. Reloading during the inclusion of bluetooth. Change the phone firmware. If it restarts too quickly for this, pull out the sim card and the memory card so that the device worked faster. Turn on the phone and quickly disconnect bluetooth. If the device will restart, then you will not come across it. If you need and desire can be installed sourid app File transfer.

Actions during physical damage device

When technical damage most likely, you need to seek help in the service center. Something you can still try to make yourself. Perhaps the cause of memory cards. Remove it and perform an action that usually provokes a reboot. If this does not happen, format the memory card. Did not help? If possible, change the new one. Remove the battery and wait 30 minutes. This will help with overheating, which could cause reboots. The phone constantly reboots Android by shocking. In this case, the battery loses contact with the contacts. This can occur if the phone is often used. You need to repaid contacts. Of course, it is better to do this in the service, but you can and yourself. Skaika is a rather subtle process that it is worth considering separately. Notice Pollution on Battery Terms? Remove the battery, wipe the connections with a cotton, which is moocked in the contact cleaner or sprite. Slightly break the contacts for a more dense connection with battery terminals. Does the phone restarts after switching on the GPS, can not start? There are several solution options. Replace the SIM card if it is much older than the smartphone.

The case can be in a memory card or settings that you need to roll up to factory.

Samsung phone reboots itself. In addition to Android, Samsung smartphones were produced under windows control Phone. The first problem of spontaneous reboots occurs more often. Solution options, as in previous paragraphs. To roll back the firmware when you need, visit the official website of the manufacturer: http://samsung-updates.com/device/
