I took my boat to a sandbar here in Miami for some footage and while I was flying my drone at about 120 meters of altitude and 60 meters distance, connection was lost and my iPhone DJI app went black and RTH was initiated. Once the P4 drone got close to my boat, it started the decent and it landed on the water since I could not control it due to connection lost screen. Anyone else experienced connection lost? since it is the 3rd time this happens to my P4 drone I think it may be a factory problem with drone. Any thoughts?
