I just got a two radio unit today and tried setting it up with my Samsung Galaxy S3. It didn't work (no connection with camera) so I contacted DJI support and they had me update firmware. So, I downloaded firmware and put it on one of the radios and then placed the card (with the firmware file) in the camera and booted up. The drone/gimbal went through a seemingly normal DJI start up but then there were no lights on the back indicating any status at all. Still no connection so I called DJI again and they determined that it was simply the device. Soooooo, I ran to Best Buy and picked up the only thing I thought would work (Google Nexus 9) and came back. Same deal, no connection in the app with the camera or drone. I guess it could still be a device issue since the Nexus 9 isn't listed as one of their (now) 5 or so compatible devices. Is there something I'm missing? Should I just try another device? It doesn't seem like an app issue at this point but I could be wrong.
