简单，反应灵敏，高效。

Lumen Auto bright is an easy to use screen dimmer application that includes both auto brightness and screen color filter capabilities. Simply set your desired minimum brightness, and you are you are done. Lumen allows you to fine tune the levels using a calibration bar.

Lumen also allows you to temporarily brighten the screen right from the notification drawer! And unlike other brightness apps, Lumen will go as bright as Android 5+ adaptive brightness will and as dark as you'd like!

Night mode will automatically place a color filter over the screen. This is particularly useful for bed time use, as blue light will prevent you from falling asleep. Configuring Lumen to filter out blue light and allow more red light will improve your sleep! Night mode can also be activate from the notification drawer.

android.permission.RECEIVE_BOOT_COMPLETED - required to automatically restart when the device turns on

android.permission.WRITE_SETTINGS - required to turn off the default auto brightness or adaptive brightness

android.permission.SYSTEM_ALERT_WINDOW - required to adjust brightness levels and enables the color filter over other apps.
