Hi! I work for a DJI reseller company, and we have some problem with a customer's Phantom 2 Vision + As he described the problem, the system works perfectly, until he is connecting to the drone with the iPhone DJI vision app. After it when the phantom tilts on the roll axis, the gimbal stops working. Disconnecting the iPhone results the system works again. He tried it with several iPhones and iPads, same result. This phantom is just returned from our warehouse (Pelikan Daniel), I don't know if they "fixed" the problem or simply sent it back, but everithing is the same. Do you have any idea?
