Just got a new phone (OnePlus Nord 3), turned refresh rate HUD in developer settings and I see some parts of the system and some apps display 120 Hz but I have problem noticing any difference, same with my wife’s Redmi Note 12, i have to look very carefully and maaaybe I notice some different, not sure
I tend to not see the difference, but I do feel it.
Whether it’s on a phone or gaming on a computer, it just feels more responsive and like a smoother experience.
