 flashlight app's code
the flashlight app will request the permission to use the camera, when hide the flashlight, it does't release the camera object. so when open the camera app, and wants to get unreleased camera will cause some error.
 
 and I think flashlight which is an 3rd app, should never impact embeded apps.
Hi Norry,
Flashlight can be downloaded from here: https://marketplace.firefox.com/app/flashlight-7?src=search
qawanted for Woodduck 2.0M and Flame 2.0/2.1/2.2. Thanks!

hi
 
 I modify the flashlight's code, and add some release code when hide the app.
 but i think it's not good to modify 3rd apps. so if there any good ideas?
Hi Reporter,
There is Arthur email at the application download page: axel.bluem@gmail.com
You can contact him directly for any code revise discussion.
Thanks!

thanks, but I think we should modify 3rd app's code as less as possible. so if there any ideas about modify gaia/gecko's code to resolve this bug?

Hi Josh,

    I am unable to repro this bug on latest Woodduck v2.0 and Flame v2.0&2.1&2.2. We have no US SIM, so I use CU SIM/ CMCC SIM instead of US SIM for testing.

See attachments: verify_v2.0m.mp4.
Reproduce rate: 0/10(v2.0m),0/5(v2.0&2.1&2.2).

STR:
1.Flash build with CU SIM (WCDMA) card or CMCC SIM card.
2.Connect a wifi and download Flashlight app (v1.0) from Marketplace.
3.Enter the Flashlight, then press the home key to Background.
4.Enter the Camera.
**Camera app works normally.

hi
 
 I try to download the app from https://marketplace.firefox.com/app/flashlight-7?src=search, but i can't find the download button on the website. so i don't know if it's the right app. 
 maybe you can try flashlight app from attachments.flashlight will request to use the  camera permission. so it can open the camera's flash light.

According to Comment 12, I try to use the flashlight app from attachments for the reproduction. Then I am able to repro this bug on latest Woodduck v2.0 and latest Flame v2.0&2.1&2.2&3.0 build by the STR of Comment 0. We get different results as shown below:

Results in step 1:
**On Woodduck v2.0 and Flame v2.2&3.0: the flashlight at the back of device is not on.
**On Flame v2.1&2.0: the flashlight at the back of device is turned on normally.

Results in step 2:
**On Flame v2.1&2.2&3.0: It prompts "Camera Unavailable. The camera is in use by another app".
**On Woodduck v2.0 and Flame v2.0:  The camera screen displays black and no any prompt.

With respect to the third party application blocking access to the camera, this should be resolved by bug 1073017. Once it lands (pending a code review), the most recent application opened by the user will force the previous owner to release the camera and then seize ownership for itself.
