Never fly with compass error!  This is my mistake, lost control for a couple of minutes. Fortunately I was able to take control and landing without damages.

Your compass was fine according to the flight record.  You had no GPS for some reason which just means you were in ATTI mode.  It's important to be able to fly in ATTI mode for when there's a problem with GPS.
Edit: Looking again, it shows GPS to be good, but for some reason it switched between GPS mode & ATTI mode.  You might want to send your flight records to DJI for analysis.

Agree.When the compass error happens, it is recommended to switch to A mode and land the drone asap.

Ok, I didn't know to switch in A mode in this situation....
But if I'm in P and gps isn't available, the drone doesn't switch to Attitude automatically?

If the GPS is not good enough when the drone in P-mode, it will switch to P-Atti mode

in Atti mod the drone can still return home... but wouldnt the drone drift and have  a hard time returning home if there is wind???? Please reply

I never understood the whole ATTI mode and RTH..  maybe if GPS is available, but if it is not, then how the heck will it return home?
I think that still depends on GPS being good....
I;ve seen some small cheap drones with "headless mode" that attempted to remember what happened and return home.. never worked..  
Not sure if I'd trust RTH if ATTI that was caused by GPS issue.
Also, I have heard that compass issues will make your GPS go wild as well...  if it's true, that could actually e a compass calibration that would help with the GPS flipping on/off like that maybe?

The RTH period of ATTI mode is the same as P-GPS mode.But if there exists the strong wind，the drone will have a hard time to go back.

I fly with compass error due to the fact that I live further north then megnatic North Pole, but I fly with good GPS reading. I can't even do follow me and 360 videos

But wait!  You can't go north of the north pole.  If you are at the north pole, any direction you go will be south!

Boy, that's a scenario that I guess would be a head-scratcher for DJI support if you ever had a problem!

Ha! Interesting!  That is not a common issue to have to deal with!

When we use GPS we set the setting to true north, wish DJI had that option, Google Grise Fiord Nunavut Canada
