Why is my drone falling from the sky?

Episode 1617 (1:21:15)

Jeff from Rockland, NY
DJI Phantom 4

Jeff dropped his DJI drone out of the sky for no reason. Leo says he hasn't heard of that problem with DJI drones just dropping out of the sky, but DJI should fix it for free if it isn't operator error. Here's a forum post talking about it though.
