Ultrasonic sensor failure after firmware upgrade

[Gabrielle]

Hi, after recently upgrading my Mavic to the latest firmware I have noticed that I consistently get ultrasonic sensor failure.

The Mavic is no longer stable in the air and it drifts and rises and falls by itself.

Anyone else had this problem? Any help would be appreciated!

All sensors are clean?

All sensors are clean?

Just checked and yes the sensors were all clean...

Very odd

How old is the Mavic, what version were you on before updating?

At some point long ago DJI have reduced some tolerance to detect some sensors that were faulty but that wasn't being reported.

Are you flying indoors in atti mode.
Try filming your mp on start up with your phone. If you here a loud clicking on playback your sensors are working.

I'm getting this error also after repair and firmware update.... Maybe issue with ios devices doing firmware updates and I've been doing updates on Android? I only get the error when I get about about 20 ft or so. Did a roof inspection today and didn't get the error at all but still experiencing drifting until I went up higher and got the error
