I flied my mavic in the morning time for two days. The temperature was around 28 degree. I had made sure the drone was in warm place before its fly. Two things I noticed that
- there was clearly jello effect even it flied straight
- the altitude reported by the drone was much higher than it was actually at

Does anybody have the same observation?

I have flown as low as 8 degrees F and noticed no Jello but did notice the altitude was high in the flight records (over 15,000 ft rather than a bit over 14,000 msl) but I believe that's based on barometric altitude so it could be OK.  I can post the video I did if you like to see for yourself.

Thanks for the reply.

The issue I noticed was about the relative altitude to the ground. When it reported 50 meters, I think it was around at 20-30 meters by comparing to the tree around it. When it descended and was just a little over my head, it still reported 6 meters.

could be fogging up or icing of your sensors.....What where the conditions other than 28 degrees?

Hi FreezeSun, thanks for your feedback, we've reported this case and our engineers are working on it now.
Just to clarify, when flying at a suitable temperature, there is no issue with the video recording, right?

1st post. Love flying and have a lot to learn.
Had my Standard up today and it was -1 on the ground. Only thing I noticed was a shorter battery life and a slightly slower response.
Got some real nice picts of the river yesterday when water was open and 24hrs later it's frozen over.
