Yes, it's been calibrated, several times. Calibration for for IMU and compass. I have not attempted a vision sensor calibration, as I fly with them off most of the time and don't think that they should be a root cause for this. The P4 Vr 2.0 (mine was shipped in June 2018) early units all seemed to have this issue (yaw during hover or inability to hover in place), and compass errors. Compass error was a inaccurate error and many complained about this, and it was fixed somewhat in one of the 2 firmware updates. I still get an occasional false positive compass error. I call it false positive since the actual compass shows fine, no error, but for some reason the DJIGO4 app puts a compass error across the front of the screen (top left). Simple fix is just do the compass dance.
The yaw issue is much more trouble some and I have had reports of pilots who purchased the Vr 2.0 in Sept and October who also have the same problem. It causes problems in both still photography and video, for me more so stills where I need to take a multiple 5 shot bracket (for exposures beyond the -1.34 to +1.34 DJI currently allows). By the time you have adjusted shutter speed for the 2nd set of brackets, the drone has moved and thus the 10 frame won't align. I have tested similar shots with my MP2, MPP, Spark and several P4 Pros (not Vr 2.0) and none of them have this issue. All stay rock solid no yaw.
The directional control in straight flight is also a bit of a problem, as the drone tends to push to the right in straight flight and when flying straight up. I have also calibrated the sticks a couple of times on the controller in DJIGO4, but no change.
As DJI has never actually agreed that the yaw issue exists (however there are plenty of posts on this site and others) along with youtube videos showing the problem. I am hesitant to send the drone in for a "repair" as I definitely don't want a different physical drone due to the odds of getting one with a camera problem. My camera on the Vr 2.0 is tack sharp, and centered by far the most important thing for my work.
I just don't understand why DJI can't fix this issue with firmware as it's only seems to persist in the Vr 2.0 P4's.
