This issue seems to be a problem with the current Phone app on the Pixel 2 when connected to Bluetooth. On my phone the app is listed as version 15.0.179075669. (I’d be interested to know if it affects other phone models – leave a comment.)
When receiving an incoming call while connected to Bluetooth, the screen goes black/blank so that you can’t see who’s calling. You can press the power button and the screen will turn on. There is no issue when receiving a call while the phone is in use – the caller ID pops-up on the top of the screen.
This will likely be a short-lived issue since a lot of people are reporting the issue in the app store, but I think it’s worth a mention since I had trouble finding information about this specific issue.
As a workaround, remove the update and revert to the original version of the phone app:
- Go to Settings > Apps & notifications > Phone
- Press FORCE STOP and press OK on the “misbehave” warning
- Press DISABLE
- Press DISABLE APP on the warning about apps no longer functioning
- When prompted to “Replace this app with the factory version?” press OK
- Press ENABLE
This will restore the app to the original version, which should be fine until a new version of the app is released.
UPDATE: This issue appears to have been resolved with version 16.0.183307769 released Jan 26, 2018.
I had the same issue on Pixel (v1).
I’m using your workaround till the bug is fixed.
Thanks
