Phone keeps restarting itself

[latchford1987]

My partners Galaxy Note 20 Ultra 5G keeps restarting at night and sometimes through the day. Usually happens a couple of times and then some nights it doesn't restart itself at all. Can anyone help as with the current situation we can't take it into the store.

I assume the setting to restart itself isn't turned On @latchford1987  in Settings, General Management,  Reset and Auto Restart.

If not then please begin by putting the phone in Safe Mode which disables your downloaded app's but let's your stock app's keep working. If the issues stop then this highlights a downloaded app as the possible issue. Come out of Safe Mode and start deleting your most recent downloaded app's one at a time until it stops. 

If it does not stop in Safe Mode then come out of Safe Mode and clear the system files cache logs. Clear your phone's System Cache Files by turning your phone Off and then from a set series of button presses go into the phone's System Files and clear the cache. No information is lost this way. You may need to insert your headphones or hook upto a computer with your data cable to get to this menu on the phone. 

Finally as a last resort back up and remove any relevant sd card and factory reset.

I hope the above helps @latchford1987
