S21 One UI 4.0

Hello everybody,

My S21 has very poor reception after installing the latest update.

Have you been experiencing the same problem?

I hope Samsung will solve this SERIOUS problem ASAP!!!

Try reset Acces Point Names. SETTING-connection-mobile network-acces point names then open the 3 dot upper right-reset. Exit,, then flight mode 2 times..u good to go

Yes, not recommended to updates. Less improvement but a lot of bugs.
