There are shortcuts for lockscreen for flashlight (hold Menu) and camera (hold Back). They are useful, all right. But I can exit from camera app by pressing Back again, i.e. bypass lockscreen. It won't work with any kind of password enabled, of course, but I don't want to enable password lock. Now, I also have glitching Back key... So, how can I disable these shortcuts? UPD. Ah, yes. Nexus S, if that matters.
