Hi @Ally3105 Go to Device care and click Menu Bar (3 dots) and Automation, are there any Auto Restarts and Auto Optimise Daily options set?  If constant restarts though  switching them off would likely not solve the issue.  I yhink it is generally beneficial to have one restart per Day.

It would be advisable to clear the cache partition,  in Android 11 and onwards  perform the following steps:

Wipe Cache  Partition

  1. Turn off the device.
  2. Connect To Computer or plug in USB-C Headphones  , Press and hold the Volume Up key and then press and hold the Power key .
  3. When the Android logo displays, release all three keys.
  4. An 'Installing system update' message will show for 30 - 60 seconds before the Android system recovery menu options appear.
  5. Press the Volume down key several times to highlight wipe cache partition.
  6. Press Power key to select.
  7. Press the Volume down key to highlight yes, them and press the Power key to select.
  8. When the wipe cache partition is complete, Reboot system now is highlighted.

Press the Power key to restart the device

If this does not solve the issue afterwards you may wish to try a Factory  Reset, however ensure Data is backed up first.

If problems still remain after all this though the device will need to be inspected.
