The original custom auto-brightness solution for Android
Lux works out of the box to provide superior automatic backlight adjustment.
Choose from four automatic modes, or manual adjustment.
Intelligent backlight adjustment means your display is never brighter than it needs to be.
Enhance your viewing experience in low light by reducing your backlight lower than ever before!
Take automation into your own hands with Lux's Tasker/Locale support
Quickly see Lux's status, and make changes on the fly!
Research has shown that displays are too blue at night, which alters your sleep patterns. Lux can automatically 'warm' your display to match artificial lighting at sunset.
Make your display red to preserve your natural night vision
If you have a rooted device, you can purchase a low level upgrade to enhance Lux even further!
