One UI 7 in samsung galaxy S21 ultra 5g

[Lxmn]

After upgrading one UI 7 in samsung galaxy 21 ultra 5g, phone is heated up all the time,

Charger connected and show charging but it's staying in same percentage.

And also both front and rear camera failed to load. I clear cache, going to safe mode and try to check camera, still the same.

I tried to reset every setting even hard reset my phone twice.

Before upgrade my phone running smoothly. 

I want to go back to previous UI.

Hi Lxmn,

With updates it does take a little time for the device to optimise, give it some time and if the issue persists, please submit an error report via the app. Our technical team will look into the issue and do their best to resolve it for you.

But how long do i have to wait. I am relying on this phone for everything it looks dead to me. After upgrade, problem in charging occurs, mobile overheating occurs, battery drains faster and camera not working so I can't to any document scan. It takes me to buy another phone.
