don't scroll the lockscreen immediately when touching a number and moving the touchpoint
When entering the PIN (user password) at the lockscreen, the entered number is immediately omitted in case the touch point is moved after "touch-down", i.e. if it's no "perfect tap", and instead the screen is scrolled.
in order to make the PIN input more robust, have the "area of the number / circle on screen" detect the number, even if the touch-point is slightly moved inside of it.
Is it clear enough what I mean?
