lux auto brightness 1 99 9999 97 apk

The original custom auto brightness solution for Android.

"To put it simply, Lux kicks the pants off of Android’s stock brightness manager, and it’s worth every cent." - Lifehacker
"Lux is a third-party app that allows you to easily calibrate your phone’s brightness sensor, saving you battery power and reducing eye strain if your phone is normally too bright in dark rooms
Lux is also able to adjust the screen temperature of your display automatically to make it appropriate for night usage. At sunset, you can have Lux automatically warm your display and switch to your Night profile. If you're an astronomer, you can enable astronomer mode to cut out harsh white light. If you have a root enabled phone, you may even be able to apply these enhancements at a low level with Lux's plug-in system.
