I was flying my P3p using Litchi way stations when all of a sudden the plane started to auto land. I was in f mode at the time so switched to p mode and stopped the descent and was able to fly the 500 feet back to me. Battery was freshly charged that day and I was on my second short flight when this happened. To my untrained eye, the log was fine. It was a bit gusty that day. My firmwares are current and the battery has been charged 27 times. I use a galaxy s6. My hands were not on the controls as I was watching the GS in action. The RC was chiming at the same time and I think it was chiming to let me know about the landing. In the Litchi log, line 1118 the mode switches from navi to landing at about 62 percent battery. The P3p would have landed in a river, had she continued. Any insight as to why this was happening is greatly appreciated.
