Auto restart overnight and freezes

[Sidex19911]

Hey,

Does anyone heve a problem with the phone suddenly restarst with no obvious reason. it happened twice when i tried to set my alarm clock, it frezzes and restarts. Olso when my phone is charging overnight, ar 3:22 am it shuts off and restarts. I discover this in the mornig when my fingerprint reader does not work becouse of the restart. I tried different chargers but the problem still appears. factory resest does not solve the problem. I monitored the temperature and also nothing strange.

Anyone have an idea what this cpould be, or experiancing the same problems?

shutdown at 3:22 am2 days in a row

@Sidex1991 first thing to do is to run the phone in Safe Mode to count out any interference from 3rd party apps.....
