What is so anno?? Just curious.. :)

Usually, some of us here including me, always clear/wipe cache partition every after big software updates just to avoid issues after the updates.

Is there a pattern to the restarts? Usually 'random' isn't really as random as we think.

Additionally there is a setting on the device so that you can schedule restarts. Hence my question :)

Hi PhantomHev, did you try to perform a wipe cache partition after the update?

I suggest you please try performing the wipe cache partition by following the instruction below and check if the issue got resolved.

Turn off the device.

Press and hold the Volume Up key and the Bixby / Power key.

When the Android logo displays, release both keys. An 'Installing system update' message may show briefly before the Android Recovery menu options appear.

Press the Volume down key several times to highlight "Wipe cache partition".

Press Bixby / Power key to select.

Press the Volume down key to highlight Yes, then press the Bixby / Power key to select.

When the process is complete, the Reboot system now is highlighted.

Press the Bixby / Power key to restart the device.

Just did that. Let's hope it doesn't restart now
