Samsung Galaxy S3 Constantly Reboots When Turned On

Often there are situations when mobile devices have to be rebooted, but there are also cases when the phone restarts itself.

We will try to figure out what can be done on our own to bring it back to life, and in which cases you need to rely on the experience of specialists.

Possible reasons

There are several main reasons for restarting the phone:

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

Quite often, the cause of a sudden reboot of the phone is a failed signal power amplifier or battery. Energy consumption increases, which ultimately leads to an emergency reboot. Replacement of these elements takes place in a matter of minutes and does not hit the owner’s wallet very much.

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

Normal 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 reboots

A fairly common problem with modern smartphones is a spontaneous reboot. The following describes the steps you must take to restore the system to normal operation.

All the time

The reason may lie in a damaged battery. To make sure of this, just pull the battery out of the device, put it on a hard surface and twist. If the battery rotates easily, it means it has a bulge somewhere or the battery is already starting to swell.

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

In cases where the battery is in perfect order, it is necessary to update the software, and with it 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 ones can just click “Update All”, but it’s better to look at the offered applications to avoid garbage in the phone.

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

When turned on

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

• reset to factory settings. The chances to return the device 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;
• pull out the battery and then put it back in 30 minutes.

Perhaps the problem is that the phone simply overheated, there are also cases of dropping the power button of the device. 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 employees.

When talking

In the case when the phone is rebooted during an incoming call or during a conversation, it is likely 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 of the rear surface of the battery (the gap between the connecting elements).

With daily use of the gadget, the case shakes, which causes the contacts to disconnect. To check if this is the root cause of a malfunction of the device, you need to shake it several times. If the device reboots again, then you should re-solder the connecting contacts. It will be easier to give the device to the service if it is under warranty.

A further cause of device malfunction may be a software failure.

There are three possible solutions to the problem:

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

After update

The mobile device may reboot after accepting the necessary updates. However, there are pitfalls here.

First you need:

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

If this procedure does not produce results, then carefully monitor which 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 deviations in the gadget, then you need to return to the factory settings and restart the device again.

The cause of the gadget’s malfunctioning can also be malicious software that got into it along with updates. In this case, you can also use the above tips, if they did not work, then you should give the phone for a flashing.

When turned on

Another common type of problem is restarting your smartphone when you turn on an application or function. The following describes the necessary steps to resolve it.

Cameras

There are often cases when mobile devices reboot after turning on the camera. Owners of the advertised iPhone are especially often affected by this disaster. The cause of the problem may lie in some application that “caught the virus.” It is recommended to start the antivirus, find the cause of 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 a shock or a fall from a height near the phone, a loop may depart.

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

In the case of other brands of phones, it is recommended to format the memory card or replace it. If the damage is not mechanical in nature, then in 90% of cases a frequent reboot is affected by a malfunction of the SD card.

To understand what caused the reboot, you should remember whether the device has ever been immersed in water or other liquid. In such cases, the device may periodically reboot, which does not annoy the host much, but this is only the beginning.

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

What to do if the phone reboots after turning on the GPS?

There are several solutions to the problem:

• replacing an old SIM card (quite often, new phone models interact poorly with old cards);
• after the gadget falls, board damage may occur, which affects the system reboot. In this case, you should contact the service center for help;
• memory card replacement;
• rollback of settings to factory settings.

Bluetooth

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

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

When starting applications

A similar incident is often found on Nokia phones.

To understand the reason for the reboot, you must:

• make sure that the battery is in good order;
• Then wait 10 minutes, insert the battery back, turn it on and go back to the application;
• if everything remains the same, then a flashing should be done.

A few recommendations on how to avoid restart problems when starting applications:

• try not to use registry cleaner programs;
• Do not download too “heavy” applications;
• Use only official software.

When connected to a computer

Restarting the phone when connected to a PC can cause 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 flashing method can turn into a breakdown, which can no longer be fixed. If the problem has not been resolved using the usual methods, then you should contact the service center.

To return your Android phone 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 conduct an experiment. try switching to safe mode. If the gadget does not go into reboot, then you can safely say that the device is exhausting one of the installed applications.

To identify and get rid of it, it is recommended to get the Clean Master application, which will give the cause of the problem. Interestingly, thanks to this program, the user can even see something that he has never downloaded.
