Can't believe this happened to me. I been flying for about a week or so. Still on beginners mode of course. Flying normal no issues, All of a sudden my phone dies, mind you I had over 60% of battery left. I'm using a Samsung Note 4. The bird started to return home, but it missed the ground by few feet and landed on my roof. My home is a 2 story house in which I don't have a latter big enough to get up there. So as of right now the bird is still up there hopefully no major damage. Just wanted to share my experience.
