Phone keeps restarting, very annoying!

[mellow_yellow]

So my S21's firmware was updated last week and since then it keeps restarting itself randomly. I have cleared the partition cache, deleted apps then finally did a hard reset, thinking it would definitely fix the problem but it hasn't! It's really bugging me, can anyone help??

So got the results back and Samsung told me it's the motherboard when it's clearly not as too many people are having the exact same issue after the update

I had a technician out the other day who ran diagnostics and found loads of errors. Thought it could be down to software issue. He got a colleague to review and they recommended a mainboard replacement under my warranty so they did that. Since then not had any issues, but it's still early days.

I have the same problem. Think I will have to go to Apple iPhone.

I have similar issues with my S21 after the recent update
