Fix the iPhone Respring Brightness Bug on iOS 6
Submitted by Bob Bhatnagar on
Sometimes respringing a jailbroken iPhone results in the display brightness dropping to its dimmest level. This quirk is all due to developers killing SpringBoard instead of backboardd to perform the respring. Although many developers have updated the respring method for iOS 6 in their apps and tweaks, some have not.
This is where BrightnessFix for iOS 6 comes into play. Installing this tweak will eliminate the display brightness issue completely by ensuring your iPhone retains the brightness level that is set before the respring.
