Pixel Filter 2.2

Quick settings tile for Android 7, by seizonsenryaku

Decrease screen brightness below minimum level, by turning off individual pixels. This way the screen contrast is kept at the same level.
Save battery on newer AMOLED screens - they will turn off black pixels completely. Especially good for 4K screens - disable all those pixels you don't need!
Includes screen pattern editor and light sensor support for turning filter off automatically.
Screen pattern is shifted each 5 minutes to prevent uneven pixel wearout.
