Try calibrating the VPS in DJI Assistant 2

I agree with AJC-W sounds like you need to recalibrate the VPS

Hi, we're sorry for the inconvenience. I would recommend re-calibrating the vision system sensor of your aircraft using the DJI Assistant 2 to see if that would help. You may refer to the link below for you to download the application to your computer. After calibration of the sensors, kindly re-calibrate the IMIU and compass of your drone. Please keep us posted on the latest progress.

I'm sorry, I forgot to mention that I did all the calibrations, IMU, Vision cameras front and bottom, compass, and FC

Any answer??? Anybody had a look to the file??

You can check the error/pup-op of it in your flight records playback.

What about FW? Latest rev?? DJI Go 4 version.
Do a complete reset of drone settings.

I'm really having issues with my drone phantom 3 it's reading barometer error  after I upgraded it to the latest firmware it's still having same issues please what should I do because I need to use the drone Asap

I wonder why nobody downloaded my flight log ??? No matter I've sent the Mavic as already (1 week ago !!) still no answer from DJI. I realize here you are lost !!!

You may have better luck starting a new thread for your problem instead of randomly posting in the middle of RoadRunner's thread...  Just a thought.
