Android reboots spontaneously. Why does Android phone restart itself - reasons and explanations

(4 estimates)

Samsung constantly reboots

Despite the fact that the Samsung Galaxy is the top model of the global brand, it, like many smartphones, can fail and start constantly rebooting. Such a breakdown can be caused by a malfunction of any program or operating system on which this phone is running.

A hardware failure can also cause problems, as a result of which the smartphone will constantly or periodically reboot.

note

Such behavior of Samsung Galaxy will cause a number of inconveniences to the user, and in the worst case will lead to a complete loss of data on the mobile device and the inability to use the gadget for its intended purpose.

What to do if Samsung phone keeps restarting? Let's consider several reasons for such a malfunction and try to find ways to eliminate it.

Reboot reasons and how to fix them

Many users, as well as more experienced service center specialists, identify several main reasons why Samsung Galaxy is constantly rebooting:

• breakage of power contacts or lithium-ion battery;
• mechanical damage to the phone;
• failure of the system board as a result of oxidation of contacts or conductive connections under the influence of moisture;
• breakdown of a RAM module or processor;
• incorrect operation of one or more applications;
• destruction of the nucleus.

We will try to independently identify several reasons for the phone's malfunctioning and, if possible, fix the problem without resorting to the help of experts or a service center. First, you need to determine the nature of the malfunction, that is, what caused it.

All types of breakdowns can be roughly divided into 2 types:

• mechanical damage- occur if any of the parts of the phone fails;
• software problems- caused by incorrect or incorrect operation of any system application or third-party program on the phone.

note

If the Samsung Galaxy is constantly rebooting, reacting to user actions (for example, pressing a finger on the screen sensor), it must be put into safe mode. With this launch, the device loads only basic system applications.

Everything extraneous programs set by the owner of the handset after activating the device, in this mode will be forcibly disabled.

Safe mode

Safe Mode is activated on all Samsung Galaxy phones in the same way. Let's take a look at how this is done on the Galaxy S6 Edge as an example.

To enter safe mode on this device, you must:

• While holding down the power off button, select the "Turn off" option. Wait until the smartphone screen goes out completely and does not take any action.
• If the model of the problem gadget includes a removable battery, then the easiest way to turn off the phone 100% is to remove the lithium battery and leave it in this position for a few seconds.
• Replace the battery and turn on the Samsung Galaxy phone.

It's important to know

At the time when the manufacturer's corporate logo appears on the screen, you need to hold down the lower key of the volume carriage, that is, the "Volume -" button. If all actions were performed correctly, a corresponding inscription will appear on the screen, which will inform the owner that the phone was loaded in safe mode.

After the final download, you need to perform any actions with standard applications, for example:

• open the file manager;
• see the amount of memory;
• check the settings;
• download system updates ();
• use a standard internet browser;
• record a video, take some photos, etc.

If, when performing such actions, Samsung does not restart, there is a very high probability that the incorrect operation was provoked by third-party applications that do not belong to the official software. This method of checking gives about 90% of the exact identification of the cause of the breakdown. In other cases, the fault should be looked for in the mechanical or hardware part.

Machine breakdowns

If the device worked adequately in safe mode, and when it went into a normal situation it resumed, the question remains what to do: the Samsung phone is constantly rebooting as before. You should start looking for mechanical damage from the removable parts of the mobile device. This could be a battery that has become deformed due to the destruction of an electrical element. By visual inspection, it is necessary to determine whether the thickness of the battery plate has increased, whether there are any extraneous bulges, dents or cracks.

If you have a standard household voltmeter available, it will not be superfluous to check the internal capacity of the battery. This procedure should be performed after the battery is fully charged, as a result, there may be 2 results:

• the sensor will show 4.0-4.2 V - the battery is in good condition;
• the value will be equal to 3.7 V - the battery is discharged.

As a result, the reason for rebooting the Samsung phone lies in low or insufficient power supply. In this case, the battery should be replaced with a new one.

Another reason for turning off or restarting the smartphone may be a small gap between the back cover body and the battery.

note

If the phone turns off during a conversation, that is, when it is in an upright position, it is most likely caused by a loose contact between the battery and the electrical circuit.

You can check and fix this breakdown in an elementary way: lay a thin layer of paper between the battery and the back cover.

What to do if the Samsung phone is constantly rebooting, and the battery and its contacts are in good condition? The restart may be caused by mechanical damage to the internal parts of the mobile device due to a strong impact on a hard surface. As a result of the phone falling, the connecting or contact wires, thermo-soldering or any other component may peel off. The motherboard, to which all the main elements of the gadget are soldered, can also crack.

Will be useful

In this case, it is not recommended to repair the phone yourself. It must be handed over to a service center for a complete diagnosis, since this procedure requires special equipment and a lot of work experience.

Samsung Galaxy software crashes

If an experienced technician or service center may be required to troubleshoot a mechanical problem,
software problems can be easily solved at home. The main challenge is to pinpoint the exact cause, namely the application causing the system failure.

There are 3 main reasons for software-related breakdowns:

• software conflict of the application with the official Android operating system;
• incomplete or incompletely installed program update;
• virus applications (spambots) or malicious software (trojans);

Let's consider each of the situations in more detail.

Installed software conflict

If after, bypassing the Play Market, the user found that the phone started to reboot, then the problem of the malfunction lies precisely in this software.

Remove the conflicting program. You must go to the section "Applications", find the problematic utility, and after opening the dialog box, press the button "Delete"... Having performed such a rather simple algorithm, take into account the fact that the remnants of the program may remain in the device's RAM.

You can permanently liquidate the application through the standard service section. Recovery Mode:

• Turn off your smartphone.
• Press 3 keys at the same time: "Nutrition", "Home", "Volume +".
• In the Recovery menu that opens, by pressing the volume buttons, go down to the item "Wipe cache partition" and start the cleaning procedure.
• When finished, click "Reboot system now" to reboot the phone normally.

Incorrect application update

Frequent rebooting of the smartphone can affect the quality update of standard applications, such as google music, maps, camera, standard browser, play market, and so on. Newer software versions may not be compatible with the existing phone model.

It will be quite simple to identify such software: it will continuously require updates, over and over again. To solve the problem, follow the steps described below:

• Through the settings menu, go to the section "Applications".
• We turn over to "Systemic".
• We find the required program.
• Open its properties and press the following buttons: "Clear cache", "Erase data" and "Remove updates".

There are often situations when mobile devices have to be restarted, but there are also cases when the phone restarts itself.

Let's try to figure out what you can do on your own to bring it back to life, and in what cases you need to rely on the experience of specialists.

Possible reasons

There are several main reasons for phone reboots:

• mechanical damage (due to impact or fall);
• crash in software;
• failure of the battery;
• malfunction of elements on the printed circuit board;
• the effect of moisture on the device (getting under the body of the device).

Quite often, a failed signal amplifier or battery is the cause of a sudden phone restart. The energy consumption increases, which ultimately leads to an emergency restart. Replacing these elements takes place in a matter of minutes and does not hit the owner's wallet hard.

The next leader in the number of calls from mobile device users to service centers is a software failure. Applications previously installed on the phone may conflict with each other, or the owner of the gadget made a mistake in choosing the firmware that did not fit this phone model.

Ordinary ingress of moisture can cause the device to reboot along with mechanical damage resulting from the device falling from a height, which often damages the main or printed circuit board.

What to do if it restarts

A fairly common problem in modern smartphones is spontaneous reboot. The following are the steps you need to take to restore the system to normal operation.

All the time

The reason may lie in a damaged battery. To be convinced of this, it is enough to remove the battery from the device, put it on a hard surface and twist it. If the battery spins easily, it means that it has a bulge somewhere or the battery is already starting to swell.

If this is the problem, then you should look at the nearest service, since swollen batteries cannot be repaired.



In cases where the battery is in good order, it is necessary to update the software, and at the same time the previously installed applications. If the gadget runs on the Android platform, it is recommended to go to Google Play and select the necessary updates, the lazy can simply click "Update all", but it is better to look through the proposed applications to avoid garbage in the phone.

After updating the applications, you should start updating the system. If this does not help, then you need to contact the service center.

When turned on

When the phone spontaneously reboots when turned on, the following methods can be applied:

• reset to factory settings. The chances of restoring the device to work in this way are very high. Each device has its own method of returning the default settings, all this can be found in the instructions for the device;
• remove the battery and then put it back in after 30 minutes.

Perhaps the problem lies in the fact that the phone is simply overheated, and there are also cases of the device's power button getting stuck. If none of the proposed options gave a result, you need to reflash the gadget. You can do this on your own or contact the service workers.



When talking

In the case when the phone restarts upon an incoming call or during a conversation, there is a high probability that the battery loses contact with the device. This is explained by the fact that during a long period of operation there is a slight backlash in the rear surface of the battery (the gap between the connecting elements).



With daily use of the gadget, the body shakes, which causes the contacts to separate. To check if this is the root cause of the device malfunctioning, you need to shake it several times. If the device has rebooted again, then the connection contacts must be re-soldered. It will be easier to send the device for service if it is under warranty.

The next reason for the incorrect operation of the device may be a software failure.

Three solutions to the problem are applicable here:

• transition to standard settings;
• firmware update;
• service center (if none of the above options helped).

Video: HOW TO FIX A RESTART

After update

The mobile device may restart after accepting the required updates. However, there are pitfalls here too.

First you need:

1. turn off the device and remove the battery from it;
2. after 15 minutes put it back and turn on the device again.

If this procedure does not give results, then carefully monitor what updates you install.

Some applications may block the normal operation of the device or conflict with each other. If before the updates you did not notice any deviations in the operation of the gadget, then you need to return to the factory settings and restart the device again.

Malicious software that got into it along with updates can also cause the gadget to work incorrectly. In this case, you can also use the above tips, if they did not work, then you should give the phone for flashing.

When turned on

Another common type of problem is restarting your smartphone when you turn on an application or function. The steps to fix it are described below.

Cameras

It is not uncommon for mobile devices to restart after turning on the camera. Owners of advertised iPhones especially often suffer from this misfortune. The cause of the problem may lie in some application that "caught a virus". It is recommended that you run your antivirus, find the cause of the concern, and restart the system.

If this does not help, then you should return to the standard settings, but before that you need to make a copy of all the necessary documents and contacts. The problem can also be specifically with the device of the camera itself; after being hit or dropped from a height, the cable may come off the phone.

The method of treatment is to open the gadget and put it in place. Craftsmen often do it on their own.

To understand what caused the restart, you should remember if the device was ever dropped into water or other liquid. In such cases, the device may periodically reboot, which does not greatly annoy the owner, but this is only the beginning.

If the phone has recently experienced all the charm of water procedures, then you should once again disassemble the gadget and dry it thoroughly. After such tests, rebooting when turning on the camera is not the worst thing that could happen to him.

Gps

What if the phone restarts after turning on the GPS?

There are several options for solving the problem:

Bluetooth

This problem is quite common among HTC phone owners. To solve it, you can reflash your phone or just never use the multimedia transfer function. However, after flashing, the device is guaranteed to work as before. You can also use a simple factory reset.

As for disabling the annoying function, everything is not so simple here either. Due to the constant reboot, the user only has a couple of seconds to turn off the bluetooth. So, you need to turn off the device, get out the SIM card and memory card. So the gadget will work faster, thanks to which the owner of the phone has 10 seconds to turn off the bluetooth, after which it will restart again, but this time for the last time.

When launching applications

A similar incident is often found in Nokia phones.

To understand the reason for the reboot, you must:

• try not to use registry cleaners;
• do not load applications that are too "heavy";
• use only official software.

When connected to a computer

Rebooting the phone when connected to a PC can be caused by malware. Check both devices for viruses. If it was not possible to eliminate the threat on the phone using the antivirus, then you should reinstall the software or reset the settings.

Do not forget that the artisanal method of flashing can turn into a breakdown that cannot be fixed. If the problem has not been solved using the usual methods, then you should contact the service center.

Phone keeps rebooting to Android

To get your Android phone back to normal operation, you need to check the date of the latest updates. This applies not only to applications, but also to the system itself.

Happy owners of Samsung phones can do an experiment - try to switch to Safe Mode. If the gadget does not go into reboot, then we can safely say that the device is exhausting one of the installed applications.

These are the consequences of malware. After uninstalling the application, you need to restart the device.

Try to carefully and carefully treat the technique, of course, mechanical damage can be corrected, but they entail more serious problems. Contact the specialists of the service centers for help, this is the only way you can guarantee to get back a properly working device.

Constant reboot is a fairly common problem in modern smartphones, especially noticeable in the cold season. The devices are simply not designed to operate in subzero temperatures. Note that hypothermia is not the only reason for endless or frequent "resets". The source of the problem can be both a fall of the device and software malfunctions. Here's what to do if the phone restarts itself without stopping.

There are several main reasons for frequent reboots.

• Mechanical impact on the body of the smartphone - fall or strong impact.
• Operating system malfunctions. This includes both errors after installing incompatible firmware and updates, and the 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 low-quality batteries.
• Malfunction of the motherboard modules responsible for supplying power.
• Liquid ingress into the phone case, which leads to oxidation of the elements and the appearance of rust.
• Hypothermia or overheating.

Problems can be caused by both software and hardware malfunctions. Mechanical damage destroys the components of the device, causing frequent resets.

An unusable battery is one of the main causes of this defect. To check the battery, remove it from the smartphone and inspect it carefully. If bumps or visible damage are noticeable on the surface, the battery should be disposed of and replaced with a new one. Bloated batteries cannot be repaired, but in some cases their lifespan can be extended:

• Using a flat-blade screwdriver, peel off the sticker from the front of the battery. Disconnect the microcircuit and set it aside, but do not pull off the controller pins.
• Using a thin needle, gently poke the battery from the side where the controller board used to be.
• Press down on the battery with a heavy object larger than its case. Vent off accumulated gas, but do not damage the battery.

Important! The above method will help extend the battery life by a few days, but replace the battery as soon as possible.

If the problem was in a faulty battery, reboots will stop for a while. The defect can be completely eliminated only by replacing the battery.

The phone restarts at the start of Android

If your gadget restarts every time you turn it on, the following methods may help.

• Perform a hard reset via Recovery. On models from different manufacturers, the entrance to Recovery is slightly different. A universal method - when turning on the phone, hold down the "Volume down" and lock buttons, when the Android icon appears - release the volume down. Menu navigation with volume switches and power button. Select "Wipe data / Factory reset", then confirm the selected action. Reboot the device with the "Reboot system now" command - the problem will disappear if the infinite reset is caused by an incorrect firmware.
• Disconnect the battery and leave the device off for 20-30 minutes. Then put the battery back in - this method may help in some situations.

Important! After a hard reset, all your data, accounts, photos and other personal information will be deleted. Follow the procedure if the gadget reboots due to firmware or update errors.

When turning on the camera

The camera application causes a restart on old iPhones after updating IOS to the latest version, and in case of virus infection. Check the device with antivirus or roll back to a previous version of the system to fix the problem.

After activating GPS

Some Android smartphones may restart when the GPS navigation system is turned on. The main problems and solutions for this defect are described below.

• Old SIM - card: some models of smartphones are incompatible with SIM cards of some operators. Try replacing the SIM card with a new one or contact the service center of your mobile phone provider.
• Memory card: SD card can also cause a reset when GPS is turned on. Remove the storage medium from the phone and check if the problem has disappeared.
• Incorrect firmware actions: perform Hard Reset if the gadget restarts after installing a modified version of the OS. How to perform the procedure is described in the picture.

When Bluetooth is turned on

Instant reset after activating the file transfer function is a common problem on HTC models.

1. You can fix the problem by performing a Hard Reset, but in this case, your information and accounts will be deleted.
2. Bluetooth usually takes a few seconds to turn on - try turning it off the next time you reboot your device. Access to the option is possible through the "curtain" of notifications - as soon as Android and the main menu are loaded, turn off the transfer of multimedia data.

When talking

If the gadget performs a Reset while talking, check the battery contact with the main board. Perhaps, after a long operation, a gap has appeared between the battery and the connector, which can be eliminated by attaching the battery to double-sided tape.

When launching applications

Some programs cause Android to restart due to poor optimization or runtime errors. The simplest and most effective solution is to remove the "problematic" application. Perhaps the problem is not in the program itself, but in certain drivers or incorrect operation of the OS. In this case, a full reset will help.

When connected to a PC

If the gadget restarts after connecting to a computer, make sure that there are no following problems:

• The USB cable is connected correctly and the cable is not physically damaged.
• Android phone or Windows PC is not infected with malware.
• Compatible drivers are installed on the computer. If, for some reason, the utilities necessary for the operation of the device do not load, download them manually from the manufacturer's website.

Conclusion

Android and IOS smartphones can restart for different reasons. In some situations, the malfunction is caused by improper firmware or applications, in others, physical damage to the device's case. Repair of the software part can be done at home, but in other cases it is advisable to contact the manufacturer's service center.

There are many reasons due to which a smartphone reboot may occur. If the smartphone has started to reboot itself and you have it under warranty - urgently take the device to the service center. Self-repair or firmware may void warranty service. If you no longer have a guarantee or you have lost it for some reason - read the article below.

The smartphone starts to reboot on its own after a fall.

If you dropped your smartphone and it started to reboot on its own, then the reason is that somewhere the smartphone's power supply circuit is broken or some element is out of order. Any device can be dropped, but repairing it can be more difficult.

So, some companies may refuse to repair at all, while others can make paid repairs. For example, if your Samsung smartphone starts to reboot after a fall, then the first step is to call the hotline 8-800-555-55-55, to clarify whether the device can be repaired. Usually, service centers go to a meeting, but you will pay for repairs out of your pocket.

You can also return your smartphone to an unauthorized service center. Choose according to customer reviews, so as not to run into outright "hack". Very often, falls bring such surprises as broken screens, breakage of the case, so in any case, you cannot do without a service center. But if you have straight hands, then you can try to repair the smartphone yourself by ordering spare parts, for example, for

The smartphone is already several years old and it started to reboot on its own.

Check the battery. It is advisable to replace it with a new one. In almost all cases, the main reason is a dead smartphone battery. In many phones, especially older ones, the battery can be removed. Modern devices, such as Sony smartphones, have a non-removable battery, but in fact it is also removable, but it will take more effort to do this. And straight arms, of course.

The smartphone restarts after being exposed to water.

Smartphone water is a huge problem unless you have a rugged smartphone like Sony. The ingress of moisture on the board guarantees the failure of the device in 90% of cases. Oxidation of contacts occurs, in which case it can "short out" in the place of moisture ingress. After getting water, the smartphone can not only reboot, but also give out other "jokes", for example, not turn on at all.

In such cases, diagnostics in a service center is required and very often the cost of repair is obtained as a new device, since in case of water ingress, the system board or the component on which the moisture has gotten has to be replaced. The store and service center will refuse to repair, as the operating conditions of the device were violated. Even after repairs, it is not a fact that the device will work normally. Therefore, if you have "drowned" your smartphone, I recommend buying a new one.

The smartphone restarts when turned on.

Most likely you dabbled with the firmware of your device or there was a failure in the firmware. What to do in this case? Perform a factory reset. On Android, this is done using the volume on or off keys, plus the power key. That is, you simultaneously need to hold down the volume up key + the power button or the volume down key + the power button.

You should get to the Recovery menu, from which you can perform a factory reset. If you have a "crooked" firmware, especially not a factory one, but some kind of mod, then in this case you will need to go back to the factory firmware. Information on how to flash a smartphone is on the manufacturer's official website, and the firmware files should also be there.

The smartphone restarts after inserting the SIM card.

Sometimes we come across such cases. I read on the forums that people complained about Lenovo smartphones, allegedly Lenovo reboots after installing the SIM card. Perhaps a solution is to change the SIM card to a new one, if you have it for several years, try to reset the settings or upgrade to a new firmware, if available. An extreme case is to try to insert another SIM card. But here the defect of the device is on the face, the device needs to be repaired. But be careful! In Russia, with the repair of devices, everything is very bad and very often under repair they mean a flashing of a smartphone. So it was with my smartphone from HTC.

Try to choose forced mode for 3G or 2G only. To do this, use * # * # 4636 # * # *, with this command you will be taken to the engineering menu of your smartphone. In some smartphones, only 3G or 2G network can be set from the settings menu. But in many modern devices this function is blocked, instead of it there is a priority of 3G or 2G. If the problem disappears, then there is a good chance that the problem is in the radio module.

The smartphone itself reboots just like that or other reasons for rebooting the device.

Check the memory card if available. Very often, it can be a faulty memory card. The first thing to do is format it. Desirable in FAT32 or ExtFAT formats.

Don't use Android cleaners. Very often, after using various cleaners, you will not only lose your files, but your device will also fail. In this case, resetting the settings to the factory settings or flashing the device will help. The best cleaner for your device - backup files and reset to factory settings! Many sites recommend using cleaners to clean your smartphone from viruses, unnecessary files and speed up the system! Know that 99% of the time this is cheating! Don't get carried away with it.

Do not use questionable programs, especially desktop launchers, which you are not sure about. Such programs can easily cause a system crash on an Android device.

If you changed the frequency of the processor, return everything as it was. This problem affects the owners of devices who have set themselves Root in order to then "optimize" the operation of the device.

As usual, comments and discussion on the article are welcome. Very often in the comments you can find a specific reason for your smartphone or ask a question.

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 spontaneous Android reboot can sometimes be fixed at home, but some can only be dealt with in a service center, if the phone or tablet can still be saved.

Reasons related to smartphone battery:

1. Poor battery contact or oxidation;
2. The battery does not correctly distribute signals to the modules;
3. A swollen or otherwise mechanically damaged battery;
4. Damaged power charging controller due to using non-original or cheap charger;
5. The battery has served its purpose;
6. Poor quality of non-original battery;
7. 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:

1. The presence of applications that conflict with each other;
2. Firmware problems (especially relevant if a custom, unsuitable, beta version of the OS is manually installed or the release has occurred recently);
3. Overheating of the smartphone;
4. Virus on the device.

This is why the phone restarts android by itself.

What to do if your Android phone is constantly rebooting. Application problems

Do you have several antiviruses, cleaners, camera apps, GPS? Algorithm conflict is 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? You may have 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 ​​Booster & 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 a 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 completed. 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 that, pull out the SIM 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 a lot. 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? Take out 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 restart after turning on the 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 reboots 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/
