I have recognized that VoLTE settings has been disappeared at new firmware upgrades. Why? How to get it back? Also there is no anymore easy way to switch only 2G-network.
I need to disable VoLTE, because it fix so much phone call issues (big delay (1-5 seconds), voice missing or go only one direction).
I found one solution to go secret menu and change to 2G-network manually. But then I need manually switch back to 4G or 5G if I want faster Internet.
Disabling VoLTE was easy and then I get good quality phone calls and after call it will automatically go back to the 4G or 5G if there is coverage.
I would like so much if VoLTE is disabled by default or it can be permanent disabled. It will help lot of people living rural areas, where phone doesn't switch automatically to 2G-network.
