BrightnessFix is a simple tweak that restores the screen brightness level after a respring.

On iOS 6 and higher when killing SpringBoard (instead of backboardd) the screen brightness goes to the lowest level, and BrightnessFix prevents this bug.

This tweak is open source: https://github.com/Maxner/BrightnessFix

Note for developers: The brightness bug is caused when killing SpringBoard to do a respring. On iOS 6 and higher you should kill backboardd to do a respring so that the Brightness bug doesn't even occur.
