Why does the SDK not allow that for third party apps? Also, why does turning the brightness to 0 entirely turns the screen off and lock it? Why is there no way to just turn the screen off (entirely dim) without locking it, and also keep it listening to touch events? (So many limitations in the SDK, it forces the developers to use inofficial method calls, if there are any for the specific case.)
