TIL. I owned an OLED phones since 2012 iirc but never noticed, or heard of anyone else noticing (on their or my device), any flickering. Will be taking my 980 fps slow motion camera to an OLED device near me soon!

Can't believe I haven't done it already actually. I've noticed that nearly everything in life flickers from microwaves (each digit is lit up sequentially! I can't believe we can't see this) to my LCD laptop screen (flickers in different colors! Red comes first, then green and blue, it's extremely obvious on the slow motion but, with my own eyes, I'll only occasionally catch a glimpse of red when I look away from something white that just turned on, and even then I'm not sure if I'm just seeing things), but the phones I looked at so far must have been LCD then

Regular LCDs like on macbooks (and I guess most laptops) flicker less. It is the drive for insane contrast ratios and pure black in phone screens that is driving OLED adoption.

I heard that it can be opposite in TV world, some backlit LCD panels flicker as hell while some OLEDs manage to flicker less but I never owned a TV to make observations
