Sometimes after turning my Spark on the video feed on my phone shows that the gimbal is panning slowly to the left or right for a few seconds, then it stops. And this happens before I even take off, so the drone itself is stationary...Has anyone else experienced this? Any solutions?

Hi, sorry for the inconvenience. Regarding your concern, would it be possible if you could show us a sample video of the issue? So we can check this on our end. Please keep us posted for further help. Thank you.

happens to me too

Mine does it too
I just regard it as a standard test function of the gimbal.

The 2 mechanical axxis gimbal for sure is not be able, to pan from the left to the right.

However, the digital 3. axxis of our gimbal seems to do that every now and then
No solution yet.
Would have to come with a new fw., methinks

my gimbal is facing the left a bit so when i turn it one i see it slow correct for yaw digitally
