Hi..Sorry interrupting. . I'm got an idea over over here..Its my first time here, so I hope ya can reply with some detailed Explanation n Tutorial :D

I was wondering if there an app or something that can make my screenbrightness changes by my action:victory: for example..
When I press home button from an app,it will make the Screenbrightness flashes to max then slowly reduce to its former setting or When I unlock my smartphone from its lockscreen the Screenbrightness flashes to max then slowly reduce to its previous setting
