Was out for a quick flight this evening and my father-in-law stopped by and was chatting and I had the Phantom hovering approximately 15 feet off the ground in front of us and without any inputs it pitched forward on its own and started flying. I pulled it back and it hovered again, yawed a little and it pitched forward again. I immediately took it down and landed. I haven't looked into anything, hopefully a momentary glitch. Anyone else have this? EDIT: I use an iPhone 6 plus with latest DJI Go App and all firmware is updated and I have latest version of iOS installed.
