Call drop issue after OneUI 4.0 update

[SarojLenma]

With recent update to #OneUI4.0 on#S21Ultra, my phone keep getting frequent drops during calls and even most of the times it gets restarted. It's so wierd, have seen the network disconnects during the calls and that's when the call getting disconnected.

This is so annoying and that's too on a expensive and top phone. Why the hell Samsung didn't find such apps crashing issue on Android 12(One UI 4.0). Not sure when Samsung providing fix for this, feeling so angry on updating to BUK7 version. Anyone facing the same and any way to fix this?

 with service center help, I did a factory reset and the above software applied. But still I have seen 20% of incoming calls getting disconnected and the phone getting restarted. I am trying to capture the app that stops running, but no luck.

Hi

I upgraded yesterday, not knowing about this issue and most calls drop out after a few seconds, incoming and outgoing. At the moment my phone is useless for making cellular calls?

When will this get fixed as it seems this has been a known issue for a long time ?
