This is a bit misleading. “PWM” can be implemented in different ways - an in fact the analysis show that Apple’s implementation is different and is causing the problem for some people.Android won't save you necessarily. Samsung OLED phones still have PWM, among other display issues.
Also those Samsung displays are great. As far back as Note 4 those things were already insanely good. You gotta give them their due on that. Sorry but don’t snipe. Instead demand that Apple match that quality - they are charging enough for the product.
