No-jun is this an intentional change?

ni?ing aosmond for input.  I think it's intentional, but not sure about the reasons to do so in 2.1.

On 2.1+, when you lock the screen, we do get a hidden event (as one would expect) and it releases the camera / forgets the zoom setting. This is the expected behaviour.

On 2.0, when you lock the screen, it would not trigger a hidden event in the app, so it would not release the camera. If the camera is not released, it remembers the zoom setting (because it is still set!). This was bad (not releasing) as increase battery drain keeping the camera active. If you were to background the app on 2.0 and reopen, it would release and forget the zoom just like 2.1.
