This is the 2nd S21 ultra I got that is overheating, especially during video calls. It must be some sort of software fault. Had 2 different software updates, and still no fix.

Did you use smarthings to transfer from old phone?
If yes try setting manually from fresh.
Or get a replacement if possible.

I did it with smart switch.
This is basically the replacement for first, they did the exchange for my first phone. But I see no improvement, so I think it might be something with software. It mostly overheats on video calls, like 10 min in.

I would try a hard reset and start from scratch as some people had luck with that and then the following updates should fix the heating issues.

I just bought a S21 Ultra and video calls are killing my phone. After 15min Video call in Line Chat, I put my phone in the fridge and my girlfriend was laughing at me why I spent so much money on that phone. Tried We Chat video call and still the same issue. I really feel bad, I was a long time xiaomk user, who didn't bought the Mi 11 because of overheating issues, spend the extra money to get a samsung s 21 ultra and now this. 

Honestly I know video calls take a lot of power and I can handle a phone which gets hot. But ***** this phone feels like it's melting right in my hands. I just registered in this forum to share and see other have this problem too...

Kind of regret my decision and my wallet too.....

Just want to point out that I set up this phone from scratch out of the box, all updates are done. 

And don't get me wrong I love this phone but I'm really concerned about this heating issue.

I guess it also could be a bad batch as some complain about the heating and some not, best to get it checked with samsung.

I've just done the new update aub9 software version and it was boiling hot after the update. so I did a hard reset and factory wiped it and I installed everything manually not through smarthings and my phone is been perfect for the last 5 hours been playing games and stress testing it and it's so much better.

I'm also on my second handset, first one I updated the Feb security patch, then started losing 40% battery life overnight! prior to the update, phone was flawless. second handset I refuse to update and is flawless. the update is messing with the phone, overheating and battery life. unacceptable in every way.
