Hey, I have connected my Iphone 5s with the DJI Pilot app and connects fine to the Phantom 3 Pro. I have noticed that the Iphone will get very hot along with the Phantom controller. Also, the DJI app which is showing the FPV display can go very jerky and slow. This often happens towards the middle / later stages of the flight and am very unsure why. I have also changed the phone to a Samsung S3 and the same problem occurs. Does anyone have the same problem or does anyone know the solution to the problem?
