How To Fix Samsung Galaxy S9 Randomly Restarting

Problem: Hello, I am having a problem with my galaxy S9. Every time I put it in my pocket it resets. Also whenever that happens, then it will keep resetting at random times after that. I have tried some solutions I have found on this website but nothing has seemed to work so far. Some of the solutions I have tried so far are: factory reset, wiping the cache partition, and booting it from the maintenance boot mode screen. Any help you can provide would be greatly appreciated.

Solution: Before performing any troubleshooting steps on this phone its best to make sure that it is running on the latest software version. If an update is available then I suggest that you download and install it first.

Since you mentioned that the phone will randomly restart when placed in your pocket then you should first try to check if it occurs when it is not in your pocket. Leave the phone in a table then check if it restarts. If it doesn’t then the phone might not be locked when you place it in your pocket which could result in the accidental pressing of the power button.

In case the phone restarts even when not in your pocket then perform the troubleshooting steps listed below.

Perform a soft reset

The first thing you will have to do in this case is a simulated battery pull or what is also called as a soft reset. This is usually done when a phone becomes unresponsive but is also recommended in this particular case.

  • Press and hold the Power and Volume down key for up to 45 seconds.
  • Wait as the device restarts.

Once the phone restarts check if the issue still occurs.

Check if the issue occurs in Safe Mode

There are instances when an app you downloaded and installed in the phone could be causing this problem. To check if this is the case you will need to start the phone in Safe Mode since only the pre-installed apps are allowed to run in this mode.

  • Turn the phone off.
  • Press and hold the Power key past the model name screen appearing on the screen.
  • When SAMSUNG appears on the screen, release the Power key.
  • Immediately after releasing the Power key, press and hold the Volume down key.
  • Continue to hold the Volume down key until the device finishes restarting.
  • When Safe mode appears in the bottom left corner of the screen, release the Volume down key.

In case the issue does not occur in this mode then it’s likely that the problem is caused by an app you downloaded. Find out what app this is and uninstall it.

Wipe the cache partition of the phone

The phone system cached data is used to speed up the access to your phone apps. Sometimes this data can get corrupted which results in issues occuring on the device. To check if a corrupted cached data is causing the problem you will need to wipe the cache partition of the phone from the recovery mode.

  • Turn off the phone.
  • Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  • When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  • Press the Volume down key to highlight “wipe cache partition.”
  • Press the Power key to select.
  • Press the Volume down key to highlight “yes” and press the Power key to select.
  • When the wipe cache partition is complete, “Reboot system now” is highlighted.
  • Press the Power key to restart the device.

Perform a factory reset

One last troubleshooting step you should consider is a factory reset. This will revert your phone back to its original factory condition. Make sure to backup your phone data before doing the reset as it will be deleted in the process.

  • Turn off the phone.
  • Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  • When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  • Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  • Press Power button to select.
  • Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  • Press Power button to select and start the master reset.
  • When the master reset is complete, ‘Reboot system now’ is highlighted.
  • Press the Power key to restart the device.

In case the issue persists even after performing the troubleshooting steps listed above then this is most likely caused by a faulty hardware component. The best thing to do right now is to have the phone repaired at a service center.
