Actual results:

1. found the radio interface still shows a status of playing, but no sound in headphones;

Expected results:

Expect mobile phones to exit camera, radio continues to play

Comment 1

[Naoki Hirata :nhirata (please use needinfo instead of cc)]

This does break the functionality when it occurs.  Noming for after basecamp.

Comment 2

[Naoki Hirata :nhirata (please use needinfo instead of cc)]

to note: when this occurs, it causes the phone to reboot.

Comment 3

[Joe Cheng [:jcheng] (please needinfo)]

Triage: BB+, C3, P2 - severe crash
Assuming base on comment 2 that the crash happens constantly when opening camera for video with FM playing in background. Renom for BB- if assumption incorrect.

Comment 4

[John Shih]

can't reproduce both on 12-18 release build and my own 12-20 build
XuJian, can you check again?

Comment 5

[Joe Cheng [:jcheng] (please needinfo)]

cannot reproduce the original issue base on STR
1. mobile phone turned on the radio;
2. click on the camera interface, record a Video, exit;

once i go back to home screen, FM radio automatically resumes

3. Enter the radio interface;

However I found that if I try to stop FM radio or change frequency here, my phone will freeze! opening another bug on this

so, It doesn't seem like anyone can reproduce the original issue, close as WFM for now. Please reopen if reproduced. Thanks

Comment 11

[John Hammink]

I can reproduce the original STR here on Ikura with following build:

Gecko  http://hg.mozilla.org/releases/mozilla-b2g18_v1_0_1/rev/54285d67454b
Gaia   c47ef39de04e634d847cc86b6acc616fabce69eb
BuildID 20130426070207
Version 18.0

Note, however, if I go to task manager, and put the FM radio in focus, the sound for FM radio comes back.   Is this how it's supposed to work?

Hi John,

Yes, it is under design.

1. Camera Recording will use content channel to pause others.
2. Content channel in background paused by others content channel will be resumed when it backs to foreground only.
