I have recently updated my phone to Android 12 One UI 4.0
After the update my phone doesn't connect to VoLTE or VoWIFi on all networks in India.
I tried Airtel, Jio and Vi.
Also earlier when I was using the device I didn't had the option for 2 SIM but now after the update I see Dual SIM card support (eSim and Physical SIM).
What do you mean brother? Reset device? I don't see an option to reset settings.
Update - I reset my network settings. Still not working.
