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.

Samsung Galaxy S3 Constantly Reboots When Turned On

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
