I was flying with my brother in law, shooting some jet ski video and having a jolly good time. At the abrupt end of the flight, the drone started going down while i was inputting command to ascend. At the same time, a notification appeared on the screen saying connection was lost. I watched the video feed which was cut short just as the drone made contact with the water. In looking at the log, it appears the altitude readings were all over the place and there was an input to ascend even as the drone went into the water. I am not an expert in this area, and would love to have someone that with some knowledge to confirm or deny my reading. Has anyone had any success working with DJI in getting a warranty replacement in this type of situation?
