its possble and auto refresh rate from rog phone 3?
so its back to 60 hz when not touching the screen?
That's not entirely how it works on ROG 3. It knows and learns which refresh rate that works best with certain apps. It also remembers after a while which refresh rate you prefer.
And a feature like you describe it won't switch back instantly, which means that it will almost never go down to 60hz. I believe you are referring to Samsungs technology which you can read more about at GSMArena
