Guy, I just noticed this on my MotoG:
1. lock phone with pattern protection.
2. press the power button to unlock
3. the pattern screen shows, don't unlock but just swipe towards left
4. the swipe works and camera switches on!!
5. I can take any number of pictures with all options turned on (recording, switch camera)
6. when I unlock my phone, the images taken are present in the gallery
I thought this is wierd as its pretty strighforward that I should not be allowed to do anything on my phone when its locked(except of course unlock and power off)
I am new to Android and don't know if this is expected behaviour or not. Any idea, anyone, on how to fix this?
