I reviewed the Brightness Level application by itself and I was pleasantly surprised with the options it offers. For example users can change the screen resolution using simple buttons such as "0%, 25%, 50%, 75% and 100%" or if you'd rather not use 25% increases and decreases you can also press the "Seekbar" option and change your display brightness with the swipe of your finger from left to right and vice versa. There is obviously no toggle since you can't simply "turn off" your phones brightness completely.
