S21U bad reception after upgrading to Android 12

[johnjohnny]

Hi.

After upgrading to OneUI 4 (Android 12), I have severe issue with my signal. The signal always switch to E even when 4G signal is strong.

Is there any solution?

Wait for next update

Are they aware of my issue though? I can't even find someone with the same issue.

If I set network mode to AUTO, I would lose Internet.
If I set to LTE only, I would lose calls.

😔
