How To Fix Samsung Galaxy S9+ Keeps On Rebooting After Android Pie Software Update

Problem: Ever since I upgraded my phone to Android Version 9  (One UI Version) it keeps rebooting all the time. I first tried to use it in safe mode hoping it was and errant app causing it but that didn’t work so  I wiped the Cache hoping that would fix the problem ( Twice actually ) still same problems. So I had to settle for a hard reset and that still doesn’t work, not only that I was hoping with that it would downgrade to its original software but it still had the one UI even with a complete factory reboot. I really just want my phone to work.  Please H-E-L-P.

Solution: Before performing any troubleshooting steps on this phone it’s 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. If your phone has a microSD card installed then you should also remove this.

Since this problem is most likely caused by a software glitch we will be concentrating our troubleshooting steps on the software side of the device. Follow the troubleshooting steps listed below to fix the problem.

Do a Soft Reset

The first thing that you will need to do in this particular case is a soft reset. This will usually fix issues caused by minor software glitches as it will refresh the phone software. This is also called as a simulated battery pull as it disconnects the phone from the battery.

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

Check if the issue still occurs.

Update your phone apps

Since your phone is now running on a new software version, the apps in your phone might not be optimized yet to run on this latest software. You will need to check if your phone apps have any updates available then update them accordingly.

  • From the Home screen, swipe up on an empty spot to open the Apps tray.
  • Tap Play Store > Menu > My Apps.
  • To auto-update apps, tap Menu > Settings > Auto-update apps.
  • Choose Update to to update all applications with updates available.

Check if the issue still occurs.

Check if the issue occurs  in Safe Mode

Another factor that can cause this problem is an app you downloaded to the device. 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 phone does not reboot 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 occurring 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.

Check if the phone will randomly reboot.

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. Take note that this will erase your phone data so make sure to create a backup copy before proceeding.

  • 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.

Do not install any apps after the reset. Try to check first if the issue still occurs. If it does then this could already be caused by a faulty hardware component in which case you will need to bring the phone to a service center and have it checked.
