When I connect my new Phantom 3 4K, the mobile screen offers me 3 choices of Phantom - Standard, Advanced and Professional. Which should I use use for my P3 4K? I've been using Professional only because the picture of the Professional model on the mobile shows gold stripes which my P3 4K has. Also, I just did an upgrade as required and now it's insisting I connect the controller to my mobile device by USB cord. Without doing that I can fly but I can't get to Camera View - no picture.. Both the controller jack and my device jack are micro-USB (Samsung Galaxy S6 Edge). The cord from DJI is micro-USB on one end but USB on the other. How do I connect them?
