1077399 - Fennec prevents screen turning off and locking

Status: RESOLVED FIXED

(Firefox for Android Graveyard :: General, defect)

Description

[Mike Hommey [:glandium]]

Since a few days (I think), when fennec is the foreground application:
- the screen won't turn off automatically on idle
- when the screen it turned off manually, turning it on doesn't bring the unlocker, and just brings me back to fennec.

I noticed this a couple days ago on a local build and have reproduced on nightlies. I haven't searched for a regression range.

Wes, this sounds like a keyguard thing… any thoughts?

Sounds a bit like bug 1072091. Are you using Fennec in Guest mode? We may also do this if your phone is just not securely locked (i.e. swipe to unlock).

I don't think I am. What is guest mode?

> We may also do this if your phone is just not securely locked (i.e. swipe to unlock).

Indeed, it's swipe to unlock. That doesn't make it fine to prevent locking, though. I do rely on the lock screen showing up to see the clock and notifications on it. That doesn't work when the last thing I did was to use nightly.

glandium, can you test in 34?

Comment 6

[Mike Hommey [:glandium]]

It doesn't happen on current beta.

We turned off the lockscreen on Aurora. Since this feature is behind a nightly flag now (and won't be turned on for 36), I don't think its worth tracking a release.

Fixed by backing out the keyguard mode.
