Hi, I was a stock Oxygen OS (3.6.1) user, today I flashed the latest rom of Lineage OS 16.
(Details:
Build: lineage-16.0-20200311-nightly
Gapps: open_gapps-arm64-9.0-pico-20200311
)
The OS is working fine, but whenever I call someone, the screen goes black and nothing works, the call is also not connected, same happens when receiving incoming calls, the caller gets the call ring, but on receiving end the screen just remains unresponsive. The phone only becomes responsive once the call is disconnected (after 40 sec when it automatically disconnects).
I am using JIO sim, and I only see the LTE symbol (no VoLTE symbol). Also, I'm unable to enable Volte provisioned by dialing **#4636#*#*, it is greyed out. I also tried dialing *#800* (oneplus logkit) but nothing happens.
I am new to all this, can someone help me what's wrong? Does Volte even work with LOS 16 on op2 and if it doesn't what's the workaround?
Thanks.
