Pixel Filter

Screen dimmer, which disables individual pixels, for AMOLED screens
Android 8 disallows any app to draw over notification panel or navigation buttons, so Pixel Filter cannot work properly on any newer phone, and nothing can be done about that.

Current bugs:
* Add Poisson-disc sampling algorithm for lulz.
* Option to start on battery percentage.
* Fix crashes when watching light level and rotating the phone.
* Diagonal lines on some devices - auto-calibrate bitmap offset using a screenshot.
* Filter does not cover navigation buttons fully when the keyboard is shown.


Although APK downloads are available below to give you the choice, you should be aware that by installing that way you will not receive update notifications and it's a less secure way to download. We recommend that you install the F-Droid client and use that.
