I recently setup a pixel 7a with Graphene os (Android 14, build 2024050300), and I'm finding mobile calls are very spotty (WhatsApp is a problem too, but I'm talking just regular calling).
It's a 2 layer problem:
- First off, when the call is coming in, the phone will not react
- once the call has been missed, it seems like more time passed, before the phone actually notifies a call has been missed. I know this because we tested it, and I unlocked the phone when the call ended, and the phone app was mentioning there was a missed call, but it hadn't propagated to the main notification bar at the top (or the lock screen), until some time later.
Any ideas on how to resolve are greatly appreciated.
