I have a Phantom 3 Advanced. I use my Samsung S6 Plus Edge with it with fully updated software. I used the drone and took footage 2 weeks ago. Packed it up and took it out a week later and the DJI GO App will not connect to the camera. Someone suggested I update firmware but all the instructions for that say to use the app to update.!.?. This Drone belongs to our local Boy Scout Council. We need more footage of an event this weekend... any suggestions?
