Oh, I may need to add that. I though you could just minimise it with the home button. Are you on tablet ?
It's a ZTE Geek2 phone; yes, I absolutely can, but using "back" button is an... expected behaviour, every single app responds to that, so that's what I did. :) By the way, it plays very smoothly and comfortably, and I have a feeling I get more stable results than on PC. Also, very elegant decision about "how to implement a precise shooting mode", I think you're very good at designing these "little things that seem obvious", so thank you once again :)
