On one of our Phantom 4 Pro's, when doing an area survey, the camera will start off facing downwards, however a few waypoints into the flight it will suddenly face all the way up and then go back down to below the negative (i.e. facing down and backwards a little bit). Before this happens the camera will become shaky, and you can almost tell it is coming. When the drone is then landing, the camera is extremely shaky and looks to be almost struggling to hold itself looking forward. I have tried refreshing the software on both the drone and controller. We have 2 P4P's, and only one of them is having this issue. Is anyone else having this issue? Any suggestions to avoid sending the drone to DJI?
