Was checking the manual this morning and noticed that the instructions for the second part of compass calibration was to point the mavic with the nose down. And I really can remember but think that the image on the go4 app prior to the last update had the image with the nose pointing down and that was the way I always did it, with out any problem. And, my go4 app usually tells me to calibrate the compass upon starting up, which I always do.
Well, yesterday when I started up just after updating to 4.1.18, it asked to calibrate my compass, so I calibrated the compass the same way I always do and got an error message, not calibrated. then I looked at the digram on the app screen and it showed the mavic with the nose/tail horizontal, not pointing down. So I held it that way and did the circle and it calibrated. So...has there be a change in how to hold the mavic during the compass calibration. So I see some have been doing it both ways. Guess I will use the one that works.
