Very strange gimbal behavior

[zvisegal]

1. While I flew the Mavic with an open type camera protector, the gimbal suddenly "flipped" and after a while was stabilized.
   
   See link to the video that was taken and compressed from the phone.
   
   Even more strange.. this video was only on the phone and was not found on the drone SD card with all othet shots.
   
   I tried to analyze the .DAT files on the drone with the viewer, but nothing unusual found during this time frame.
   
   Any ideas ?

I've had this happen a couple of times. Same series of events where it freaks out, then stabilizes and a few seconds of footage is in cache but not on SD card.
