Screen Brightness Control Lite

The original easy auto brightness solution for Android.

Lux isn't your stock brightness app. It wisely adjusts the brightness of your display based on environment light. Lux will automatically lower the brightness of your display to make it not only comfortable to read, but to also preserve battery power.

Lux is also able to adjust the screen temperature of your display automatically to make it appropriate for night usage. Lux is completly automatic. Just teach it how to behave and it will dim or light your screen for you!
