Summary
Black screen when receiving or giving a call
The problem
I'm getting a black screen when receiving a call. The same happens some time when giving a call which is embarrassing when consulting your voice mail and you need the virtual keypad to navigate through the voicemail options.
Receiving a call:
- tell someone to call you
- the Moto G7 is unused and locked (screen is black)
- when your Moto G7 is ringing the screen is black and you cannot see who's calling you, you cannot answer or use the calling options normally shown on screen for that matter
Note that if the screen is unlocked and you're using the phone, then it works normally, you can see the caller's ID/name and answering options.
Giving a call:
- pick up the Moto G7
- open the call application
- call someone
- then some times the screen goes black...

Workaround
To be able to answer the phone I configured the volume button to answer the call and the on/off button to hangout the call.
It is possible to answer the call swiping the screen from top to bottom to see contextual information and then press the answering icon next to the incoming call message.
Possible fixes
I'm not a developer so I don't know how to fix this issue. It seems to be related to LineageOS 17.1 as I do have the same issues with it too, but it worked fine with the Motorola's Moto G7 stock ROM until I unlocked the phone, erase it and installed /e/.
