Hey guys

I am using a Mavic 2 Pro with the smart controller(not so smart is it? I've got a whole separate set of issues with that) all firmware is current and I am using the latest DJI go 4. I have had this aircraft for maybe three months now and ever since I first got it I have always felt a little disconnected from it and don't feel as confident flying it as I do with other Mavic 2s or RC aircraft in general (I have been flying RC helis for about 10 years). I have recalibrated compass, IMU, vision sensors, and also reflashed firmware multiple times with no luck. There is nothing obstructing the gimbal and all the sensors are clean.

Here are some of my symptoms that occur in active track, point of interest, and quick shot. All of which use sensors which makes me lean toward this being a hardware issue.

Frequent subject lost errors, even when the subject isn't even moving followed by erratic behavior by the gimbal I suspect because it is searching for the subject

Yesterday was a new one, at first the aircraft started to yaw rapidly on its own while staying stationary in point of interest mode rather than circling the subject, then decided to increase the radius and appeared normal

In active track mode, in any of the three modes, control inputs on the sticks are completely wrong. Somebody told me this might be by design in a intelligent flight control setting but I get to find anything about that. Giving the aircraft right role moves it either forward or backwards and giving the aircraft back elevator moves it on the roll axis one way or another. And it is not consistent or relative to the subject.

Quick shot Helix do not accurately circle the subject, rather seems like it bounces off or is being stretched with a rubber band.

Here are a few examples of what is happening. I have submitted a support request to DJI however in the meantime I'm hoping one of you are able to help.

Thanks in advance!

your post little bit aged,don't know if you have already resolved this scary issue but did you try new version of GJI Go 4 .25 (not the unofficial site but from the official site?)
Today , during my AT,  I lost the track without any reason while I was tracking a rowing boat on the lake.
My altitude was 23m ,no wind ,no any obstacle around and between me and drone and drone and tracked boat.
Active tracking started normally and about 50 m tracked the boat with normal cruise speed (<12m/s) and after a while suddenly and without  given and message  lost the lock even the boat was still on the view.
M2P turned the head 180 degree  to the direction where the AT started and  when doing this,  a spilt of second  I even saw the front left propeller on the camera view probably  when turning the head  M2P tilted down ( like can see during sport fly)
moment drone was hovering and not accepting my stick movement.
AT cancel  button  (x) was also not responsive for few  second (10sec) then eventually  managed to back to normal fly.
  
I never done this kind AT on water it was the first trial and scary.
Back to home and install the DGI G0 4 .25 from the official web site ( earlier I installed same version but from unofficial website. don't know if this was the  culprit but will give a try next time to see how it will works.
Apart from that POI has  no probelem on my today flight.
