The M20P is a great phone in many ways but I'm throwing in the towel. At this point I really wish I had held onto my P20P.
I can't trust this phone as a daily driver because of intermittent issues where phone calls go straight into voicemail without the phone ever ringing. It's not like I'm missing the calls because multiple people have reported that when they called it went straight to voicemail with no ringing.
There was some theorizing in a separate thread that the issue might be due to a compatibility issue with the T-Mobile network here in the United States (where the M20P isn't officially sold or supported) but I have found owners in other countries complaining about the same problem .
I've tried numerous fixes from experimenting with the APN and network settings, turning off raise to wake and voice answering settings, using performance mode, using Shortcut Maker to disable the hidden Wi-Fi calls menu, turning off power optomization for all apps, giving call related apps unlimited data access, disabling Power Genie with ADB--and every time it seems like the problem might be fixed it eventually happens again.
I previously owned both the M10P and P20P and never ran across the issue on either phone. I'm not sure if this is happening because of MIUI 9 or the way Huawei is implementing Android Pie or if it is only specific to this model but as much as I like the M20P I can't use it as my daily driver if I can't trust it to ring every time I receive a call.
I'm not a fan of Samsung phones, One Plus or Google Pixels so I'm looking at probably getting a Xiaomi MI 9 and relegating this to the back up phone status currently occupied by my Mix 2S.
Maybe the problem will get fixed in the 9.1 update but I can't keep missing calls.
