I can reproduce this. Start with screen blanked. Cover top of phone with something., so it covers the proximity sensor. Call that phone from another one. While it is ringing, lift the cover off the proximity sensor.
See that screen stays blanked and only way to unblank it is to push button. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unity-system-compositor in Ubuntu. https://bugs.launchpad.net/bugs/1524648 Title: Display doesn't turn on for incoming phone call when proximity sensor triggered Status in Canonical System Image: Incomplete Status in telephony-service package in Ubuntu: Confirmed Status in unity-system-compositor package in Ubuntu: Confirmed Bug description: I just received two phone calls. In each case the phone started ringing but the screen stayed black. In the first case I let it ring for a while hoping that it would magically wake up, since some bugs do seem to work that way. But nothing happened. I was unwilling to press the power button since in iOS that immediately hangs up the call. Eventually however I did press it, and the screen woke up. But I was too late to answer the call. When the person phoned back the screen was black again, so I pressed the power button and was then able to slide the slider to answer the call. I don't think this is the same as Bug #1493574, since that bug seems to happen after the phone has been answered. Syslog of about the right time attached. Phone reports the times of the calls as 15:41 and 15:47.
