    Hi,

    Today, I freaked out .....
    At 50 meter height suddenly the obstacle alarm sounded on the controller and the app.... and there was nothing in the neighbourhood (????) ...... I descended the Mavic quickly and some small hiccups during the descend ..... The alarm sounded continuously ....

    Reason: The Mavic was looking directly in the low winter sun.
    Solution: Ignore it and turn a few degrees and the alarm goes away ...
    (I did several other flights with the same alarm if you do 360 degrees turns, But rock solid. :) )

    No worries, all okay and happy flying to all !!

    Yup happened to me a couple times...Just a few minutes ago as a matter of fact. I also suspect glare when flying over water and descending to be cause of auto landing that I experienced last week. I was holding the left stick down and it went into landing mode...This is overridden by pressing left stick FULL up.
    FORCE LANDING WTF?!

    I will be disabling all vision sensors from now on unless I am flying within tight quarters. I am used to flying without the nannies and usually fly above and clear of any obstacles.

    Just ran into this as well. The best solution I guess is to turn off avoidance when forced to fly into the sun...?

    Would like some ideas on the Obstacle warning, as well.

    Happened to me yesterday 17 Dec. Went for a flight in NH after the snowfall stopped. Ascended to 200ft and began heading due East. There was no sun since the sky was still overcast heavily from the snow front that had gone thru. No snow was descending during my flight.

    There weren't any obstacles in my path. I got warnings and flight stoppage at least 4 times. I traveled about 1000ft from my Home point. I decided to bring the Mavic back in after the last warning. I was flying with the Gimbal cover on (although I wouldn't expect that to matter).

    Any guesses what's going on to kick the warning on?

    Not flying through/around fog? That will trigger it also.

    Had it happen to me back to back over the ocean in Hawaii. Scary stuff. Had to fly zig zag routes to get it back to shore with not much battery left the first time.

    Put it in 'S mode which turns of collision avoidance then back to p mode
