When you activate the props, do you leave the Mavik on the ground (floor) for a while, or ascend a few feet?
I don't have any knowledge of the barometric sensor location or when, in the initiation process, the reference pressure is taken - immediately upon power-on, immediately upon prop activation, or a few seconds later. However, I can conceive of a situation where the drone, on a flat surface with props whirling, could create a higher pressure zone around the lower body of the drone during the baseline pressure reference measurement, thus leading to a negative (relative) pressure reading while hovering.
Just thinking out loud :-) Maybe the DJI software folks could shed some light on the initiation process.
Try ascending a few feet immediately upon prop activation.
