In the dji go 4 app it says I need to calibrate the avoidance sensors to increase accuracy. When I click on the calibrate button in the assitant I get an error "[size=14.6667px]Frame Alignment error" and won't go past there. Also says Please reboot aircraft which I have.

Not sure what is happening here but this video may help if you have missed something:

Did you leave the Gimball lock on when you turned on the aircraft?

What happens when you turn off the aircraft and re-start the app do you still get the same error message

I found out what it was, Windows 10 didn't install all the drivers correctly. After holding the shift key while booting into windows I was able to get the drivers installed and finally got the dot's to show and was able to finish the calibration.

Glad you got it sorted out. There's no need to calibrate the sensors unless the app asks you too.

I spent hours trying all the fixes in this forum - i tried two different windows 10 machines and then booted to a win 8.1 and nothing worked - finally i installed win 7 on one of the hard drives ... shazam !
