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.
I use grapheneos on A P7 pro. Banking apps work fine because the bootloader gets locked with grapheneos. This is what most banking apps would complain about. Also if it for some reason requires google play services this is available too in a sandboxes way.
