I think this might be related to the phone powering on the screen after a notification. That is: I believe the occurrence is higher after the phone has woken the screen (and perhaps then timed out), compared to when there was no notification since I last used it. This is because it seems to affect me more when I'm responding to something (eg. notification LED with screen off) versus when I have taken the initiative to use my phone.
I also haven't seen this since OTA-7, where other bugs related to screen power seem to have been fixed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1429887 Title: Sometimes need 3 power button presses to turn on screen To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1429887/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
