Just an idea that came into my head: Is it possible to dim the screen while torch is in use?

Another idea: the camera button launches the camera application but only when the screen is on, when the screen is off (switched off with the side button) it doesnt.
Maybe it is possible to use the camera button when screen is off, camera cover open and lanterne is running?

(btw what application is used for selecting what happens when you open camera cover?)
