Sors , via OnePlus 7 Pro , Nov 10, 2019 at 9:13 PM : Since I received the Android 10 (Oxygen OS 10.0.1.GM21AA) on 18th of October, my phone (OnePlus 7 Pro) doesn't ring when my Mum calls me. (not only doesn't make sound, but nothing happens) Here are a few things I already ruled out: - Her number isn't blocked - Do not disturb is disabled - Forwarding is deactivated - It's not a network problem, because my SIM in another phone worked just fine - I've tried deleting and saving the contact again, no success As well as some hopefully useful information: - After my phone didn't make anything when it should've been ringing, I'm not getting a missed call notification either, and the call doesn't appear in my call history. - On her phone the call rings out as if it would be ringing to me. - Every other contact of mine from different network providers are able to reach me. - I am able to call my Mum right before or after she can't reach me as well as any other time. - She cannot reach me as a private number either. - If I try to make another call while she's calling me, the call doesn't ring out and ends automatically when she aborts the call to me. - The problem exists since the Android 10 update.
