CustomBrightness cydia tweak is a replacement for the default auto brightness feature of iOS.
It allows you to specify the display backlight level of the iDevice for the current ambient light. The app always runs in the background and adjusts the display brightness as the ambient light changes.
Not compatible with iPod Touch 5th generation.
Configuration app on home screen.
CustomBrightness is designed to replace auto brightness of iOS. So iOS auto brightness must be disabled for CustomBrightness to work properly.
