My phantom 4 pro when flying will momentarily show something close and there is nothing there, Can it be picking up bugs in the air I can see there are no birds around.
I calaberated the vision sensors and still the same issue, should i do a firmware refresh. All the censers are clean.

I see in some other post that it might be a firmware problem? When using DJI Go should the version show refresh or just version number. mine shows refresh could that be telling me to refresh firmware

Are you sure it is not facing into the sun where the sun is at such an angle that the sensors are picking it up?

that is a probality. I will pay attention to that.

Hi, thanks for reaching DJI Forum. We do appreciate bringing this query to us. When was the last update you performed on your aircraft? Yes, it could be the bugs but we have to be certain that there are no problems with your aircraft. If you may change your location and fly the drone and let's see what happens.
