Luxury is a tweak recently released in Cydia, and with its help you can modify the functionality of the ambient light sensor implemented in our iDevices. The ambient light sensor changes the brightness of the screen when you pass from an area with low light to an area with strong light. Using Lux, you can modify the way this sensor works, increasing or decreasing the time period in which it reacts, but also the level of inclination that activates it.
Lux allows you to adjust the Ambient Light Sensor (ALS) bell curve, time sustained to change brightness, and many other interesting settings all related to the ALS
Lux has a settings menu in the iOS Settings app and is available in Cydia's BigBoss repo.
