What is Night Filter?

Night Filter is an application that allows you to change the screen brightness and color on your Android device. This is perfect for use in the evening and at night, when the lighting is dim and the screen should be lower in brightness. You can also use it to dim the screen in the morning and evening, to help you wake up more easily and stay alert for a longer period of time.

How does it work?

You will need to install the application and open it. You can change the brightness from 0% to 100% and the color from 0% to 100% or from black to white. You will also have the option to use the service to dim the lock screen and notifications tray.
