[Blocking Requested - why for this release]: Unrecoverable without a hard restart of the phone.

Potentially related to Bug 1092391

When my alarm sounded, I snoozed it and turned off the phone's display.

When it sounded again, the display was stuck in a weird half-alarm/half-lockscreen state. (see screenshot)

The alarm's snooze / dismiss buttons aren't responsive. While the lockscreen was responsive, I could only get at the bottom three buttons of the PIN pad, and thus could not unlock my phone.

My only option was to hard-reboot the phone, losing my open tabs in the process.

I cannot reproduce this bug. Alarm overlay always appeared correctly over lockscreen. Also tried steps in bug 1092391 and couldn't repro either. Bug repro rate: 0 out of 8 attempts.

I could not reproduce this issue after several attempts on Aries Master. I tried different phone orientations, passcode and lockscreen. I also tried with the phone being plugged in and not plugged in but the Alarm overlay always appeared correctly.

I was also unable to reproduce this issue. I attempted multiple alarms at once, with and without a passcode lock enabled. I tried triggering the alarm right after the screen timed out, when the lockscreen was open, and when the passcode keypad was active. The full screen alarm UI and Software Home Button always appeared and functioned properly.

Repro Rate: 0/10

Dan, can you see if you can still reproduce this issue on the latest build?

That's the thing about races :( I haven't been able to repro since it happened back in June, but it definitely happened then.

Greg, could this be connected to the recent architecture overhauls?
Flags: needinfo?(gweng)
I think it's related to Software home button since its height match that exactly, and I don't think it relates to architecture.

If there are stable steps to reproduce that, I can give it a try after the current very long handling task queue ends.
