iFix Brightness for 6.x solves the bug of the Brightness function in iOS 6

  If you have installed iOS 6, then you probably encountered a problem that affects the auto-brightness function of our iDevices immediately after performing a respring. More precisely, if you install a tweak or do a simple respring, the brightness of the iDevice's screen will automatically be set to the minimum value and either it will recover with difficulty or it will not recover at all. This problem can be easily solved with the help of tweakacquis iFix Brightness for 6.x which was launched last night in Cydia.

  After performing a respring, you will notice the same effect of decreasing the brightness level, but the tweak will return it to the normal value in just a few seconds. iFix Brightness for 6.x it is available for free in the repo ModMyi al Cydia and it only works on iOS 6.
