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.
The orientation of the device is strictly controlled by the accelerometer. The tweak changes the reporting period of ambient light data, but relies more on maximum and minimum brightness control. I've been using it since it appeared, and I even made some requests to some developers to work on something like this. Without Lux, usually, when I was out, the screen lit up way too much for no reason, and consumed the battery very quickly, like this. With Lux, you adjust the maximum and minimum brightness yourself. An excellent tweak!
I see that it also specifies the orientation there.
Yes, but it refers to the brightness control (presetting) for landscape or portrait.
But can I get this function from the AppStore? I have an iPhone 4. This app would be very useful. Thank you
@Irina: Nope.
