My S10+ is otherwise an awesome phone, but the OLED PWM is really taking its toll on my eyes. I can't read anything on the phone for more than a few minutes before my eyes start watering quite a bit and a headache starts forming, which is something that doesn't happen on LCD displays without PWM. Some Android manufacturers such as OnePlus are already offering DC dimming as an optional feature, but I really wouldn't like to go there as the camera isn't as good and for security (both updates and how actual security feature are implemented) I trust Samsung way more than OnePlus and other Chinese manufacturers.
I'm perfectly aware that with DC dimming on some colors may be skewed, but I can live with some colors being off if it means that I can actually use my phone for prolonged periods. In optimal scenario there would be a quick settings toggle for DC dimming so that it could be disabled when reviewing photos or other work where color accuracy is more important. But if it were at least available buried deep in advanced settings would be a nice start.
