Home PWM flicker
Apps whose makers say they act on PWM flicker
PWM flicker is the fast on and off switching some screens use to dim the backlight. These are the apps whose makers say, in their own words, that the app acts on it, most often by dimming the picture in software so the backlight can stay higher.
4 of 15 apps say so in their own words.
