Are you on the Beta version @Dan4077777 

I've seen that the Beta programme is coming to an end and Samsung will soon start sending out the finished version to eligible phone's but not that fast.

It's great if you've received the finished version. 

I would suggest clearing the phone's system files cache via 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. https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ 

Also check your phone isn't set up to restart as set time's via it's settings.

Lucky you 👏 @Dan4077777 

Can you try cleaning your cache as I mentioned and check your settings.

One other generic troubleshooting tip is to try Safe Mode which disables your downloaded app's and theme's etc just incase one is causing the glitch.

Also please ensure your apps in the Playstore and Galaxy Store are updated.

On a personal note how are you finding android 12 and Samsung One Ui 4 ?

Follow my link above.

Remember you'll need to insert your headphones or hook upto a laptop. No software is needed on the laptop as its just the process of hooking upto the laptop that's needed.

Did the clear Cache work for you? My S21 ultra started rebooting through the day and night after the new one UI update.

Cleared Cache and its still rebooting.

Cant really use Safe mode for long periods of time since I need to be on the other apps for work.

Looks to be an issue with the UI update as the last 6months the phone has never done this
