I just got my P3 from Best Buy yesterday and have only flown it once. The first time I flew it I didn't calibrate it and now this time my drone won't take off unless I do calibrate it. When I calibrate it horizontally it works but when I do it vertically it says I'm too close to something metal which is not true because I'm doing it away from the phone and controller in a very empty open area. What could be the problems ? I'd really like to fix it
