I don't understand, turning on the screen? You got a volume knob. No need to turn on the screen.
There's a setting. I tried it off and changed setting to leave vol. control active.
As for the rest: I don't look at the screen, so can't help there. And, I think the world has WAY to many touchscreens. Nobody seems to like wheels, therefore, maybe they could put a 4-way toggle rocker thing on version II. But PLEASE, QUESTYLE, no touchscreens I beg you.
I'm sorry that Questyle chose to make their DAPs accessable to all.
