I was flying my P3P and it lost signal, and returned to home. The app showed no signal at the top, but I could still control the gimbal, and maybe the aircraft, I didn't try the joysticks. I shut the aircraft off, and turned it back on and it worked again. After flying for about 5 minutes, the propellers just stopped, and it fell about 15-20 feet from the sky and landed hard on the front right arm. It bent the frame just behind the arm and the metal casing of the motor came off. All the propellers were still attached. When I went to pick up my drone, the power was still on, so that confused me. I didn't pull the sticks down and in either, I know that is a way to start/stop the motors. The battery was fully charged when I started, and was about 75% after the restart of the drone. I checked the flight record and everything was good as far as I can tell. The warranty seems kind of confusing and I don't know if it falls under the "Following situations are not subject to warranty service conditions" since it was a crash, but it was out of my control. How can I go about this situation? I have only had the drone for 4 months.
