Screen Dimmer: Reduce Flicker is a utility app designed to alleviate eye strain and headaches caused by PWM on OLED screens. By replacing the system brightness management, this app offers adjustable auto brightness/manual brightness modes, a customizable pixel filter to reduce screen burn-in, and a brightness bar notification with dim duration settings. Additional features include an extra dim option, Always on Display mode support, and the ability to take screenshots without the filter. Note that the app does not cause display burn-in, as it maintains screen pixels lighting at the same level as the system brightness.

For users experiencing issues such as eye strain from PWM or the app not dimming correctly, troubleshooting tips are provided within the app to address common concerns, ensuring a smoother user experience.
