VoLTE Not working after Android 12 One UI 4.0 Update

[ashutoshthakur]

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.

With A12 UI 4, for some carriers, volte is auto enabled and not a selectable option.
Contact your carrier for more details.

I am in the same boat as you. Calling not working for me after One UI 4 update.

Do you have the Snapdragon version by any chance?

[ashutoshthakur]

Yes. I am using the Snapdragon Processor model

I am curious if porting my physical SIM to eSIM will work or not? What do you think?

[ashutoshthakur]

No it will not. I don't think so.
