I tried to connect to two new PV2+ after battery charge's (Main and Extender), When the DJI App opened, there were more than one "Phantom_00000" showing to try to connect to. Finding one that would connect, it would either connect, then immediately go to "saved" or connect briefly, the camera would come on, then go blank. This was new, out of the box. No firmware upgrades attempted. I'm starting to think my control device is the problem, 2013 Nexus 7 w/4.4.3 ver Android. I used it 100% successfully w/my PV2. My Cell is not compatible, and I don't want to get into a new "contract" for a IPhone! Bad luck or user error?
