My phone is losing regularly GSM network during calls and people are saying that they cannot hear me. Is there any fix of this? I have already tried to disable WiFi Calling, 5G, restart the phone, etc. but those problems persist. I wasn’t able to find reliable information on the internet that could help. If someone is experiencing similar issues and found a fix, let me know.

Alternatively, I can also install some other ROM, but I want to keep this as a last option. In this case feel free to recommend any good and stable ROMs.
