Noob here. I have a Samsung Note 4 that I have been trying to use the app with my drone. 1) The screen is small and highly reflective, and 2) shortly into the flight I have no control of what I can record. The record buttons go grey and I can't switch between vid and still. Is this an Android issue? If so, I'm about to go buy the IPad 4 mini. Would this be a wise choice? I know it's a bit thicker and might not fit on the device holder on the RC. How do I get around that issue?
