This works if you use unprotected swipe to open. But if you add security such as a pattern, PIN or password it doesn't - you have to enter security swipe etc.
Shame it doesn't work like the iPhone where you can still get quick access to camera even if PIN protected. When you quit camera iPhone takes you back to lock screen!
