Goodmorning,
I have a problem with my Phantom 4 Pro it gives me the attached message.
I've already done the calibration through the app DJI Assistant

How can I solve this problem?

Thanks, have a nice day
Luca

Do you have a gimbal guard installed?

Hello,
Thanks for the reply,
I have no gimbal protection

Thanks

You may want to have a read of this thread. Same problem but no resolution.

Hi Luca, does the issue appear frequently? Do you mount any accessories on the drone? It would be better to change the flight environment to see whether it remains.

I also have the same problem, even changing location
Phantom 4

Have you tried calibrating the Downward VPS with the DJI Assistant 2? Follow this link:

Done twice and both times DJI Assistant said it was ok

Have a close look at the downward sensors (cameras & ultrasonics) and make sure there's no dirt or grit causing problems.

Edit:- also front/rear visual sensor cameras for completeness.

I did some tests, I went back to the previous firmware and the problem did not occur in any way, I reinstalled the last version and the problem came back
DJI Help, Help, Help

Without further testing, with the previous firmware the problem is eliminated, I would ask the DJI to remedy because leaving the new firmware with this problem is of enormous danger, the phantom comes down in a swooping and if you are not careful you risk destroy it on the ground

Si sono italiano,purtroppo tornando al firmware precedente si hanno altri problemi, la stabilità del phantom 4 è andata a farsi friggere
