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 Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1524648 Title: Display doesn't turn on for incoming phone call when proximity sensor triggered To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1524648/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
