During a flight earlier today I got a bit worried when my P3S started behaving weirdly. Before the flight I calibrated the compass, as always, and I took off where I've taken off many times before. The temperature was -6°C (21,2°F) and there was pretty much no wind. Here's a one minute video of what happened. The first odd thing I noticed was that the drone didn't really go straight. It started to turn slightly by itself and at the same time the gimbal started to tilt. Suddenly the DJI GO lady told me the flight mode was changed to Atti. Looking at the log, though, the drone was in contact with at least 10 satellites during most of the flight and it was only in Atti mode for one second. I decided to turn back and on the way back I thought the drone started to dive. I was slightly less worried when I saw that the altitude didn't change. For some reason the gimbal had tilted down, so I brought the camera back up again and it tilted itself left and right. I finally reached my landing zone, so I pointed the camera down and started the descent. Before landing I flew around for a while at an altitude of 3m to check for any odd behavior, but nothing else happened that was out of the ordinary.
