Installation question

twitheatrophonic

I have installed graphene. I can't make calls from 3 4 months. Only solution i got is reinstalling graphene. Do i need to install stock os first or i can just install graphene again without installing stock first?

Have you read up and followed the carrier functionality usage guide? Have you tried that sim in a different device? Perhaps some more details will help others reading this, help you.

Doing a factory reset is quicker and does the same thing.
From the Settings, Tap System And then Reset options And then Erase all data (factory reset).

twitheatrophonic Can you confirm if you have Wi-Fi calling enabled or disabled? This has personally been a issue for me where calls drop if Wi-Fi calling is not set in the SIM holder's account.

akc3n already tried factory reset
2 times didn't work? No other option then?

The problem is I'm not getting phone calls. If someone calls, it'll not connect or it'll only get notifications of missed call. I tried factory reset, apn settings, changing sim, deregistering esim converted it to physical sim nothing works. Sim is working fine in other mobile though

twitheatrophonic I am not familiar with cellular carriers in India, so maybe somebody else will chime in.

Some carriers require 2G or 3G for calling even if data traffic is 4G/5G. Is the "Allow 2G" setting enabled?
