I am unable to reproduce. 

When I launch torch and launch camera, I see the "Camera is in use by another app" message displayed by Camera App. And when I closed the torch app using task manager and go back to camera, message is no longer displayed and I am able to take a picture.

Hema, here's the repro video.  I can reproduce this bug consistently.

Looks like from the video, torch has captured the camera stream and until it lets go, other apps that need the camera stream cannot use it. 

But there is another issue after the torch app is closed where you are not able to use the camera (its not capturing). Blocking for that reason

Thanks
Hema

Investigating now that I got the torch app working again (previously broken as noted in bug 1111376).

This issue is verified on Flame 2.2.

Result: The "Camera is in use by another app" message does not appear when Camera is launched while Torch app is running in the background. And the user is able to take a picture after closing the Torch app from Task Manager.
