Note 20 Ultra Random restarts

[turbo_geoduck]

My Note 20 Ultra recently began randomly restarting.  It has done it at least 8 times in the past week. Any ideas why, and remedies?

I have this same phone and same problem. It started after the last Android update. I"m on version 12 now. I never had this problem before I went from 11 to 12. Can i rollback to 11? 

My software update page says 
Software updated to N986USQU2FVEB

You're all set!
Your Phone has been updated to the latest software version. 

It still continues to restart randomly, even when it is just sitting on the charger untouched.

brucedabull,

With software, there is no way to reverse back to an older versions.
