P4, After Latest successful Firmware update AC via DJi Assistant and RC via DJi Go app, and the new IMU calibration, i got a "IMU Error. Calibrate IMU" message when i start it up again, although the IMU bar in the app is green(but small), after a while warning disappears and Ready to Fly appears.
I did Gimbal calibration, and everything seemed to be OK, but restarting for a test flight gave the same "IMU Error "
I tried to do a "vision" calibration with DJi Assistant but i couldn't enter into the calibration page( i looked the help pages) see screenshot

Explaining this problem documented with screenshots with DJi support they ask me to send the P4 in for analyzing .

So far i only tested real flight after that i got a green topbar, and it flies normal in the backyard, i don't risk further flights.
I calibrate the P4 each time with the greatest caution on a leveled platform, away from any metals or magnetics and following the latest manuals.
Should i send it back?...

Don't worry about it.

Many of us see the IMU error while it is warming up, but it goes away once it is up to temperature.

Like Mark said, the consensus seems to be a bit of a software bug that displays calibration error when actually should say IMU warming up. Hopefully the next update will fix that.

Thanks for replying, i did some flight tests today in the open anyway and nothing seems to be wrong, au contraire, i tried some new intelligent flight modes like Draw an Tripod and they are great.
Also RTH works good, so i will hold the bird where it belongs.
