I flew exact same location over 20 times, and I had never received any warning messages about strong interference and weak signal until today.  Had anyone run into this problem?  I just upgrade to latest firmware, the first flight after the firmware upgrade was fine, this 2nd flight was problematic.  But one thing to noticed is that I was using a different battery.  Not sure if that could cause it.

I don't think the battery would have anything to do with it.
Can you try some different areas, also you have the antennas in the correct orientation right?
You can also perform a factory restore from the Assistant2.

And make sure you have a good compass calibration.

@ken, the antennas was always the same way I had used since getting the mavic on Oct 25. I'll try it at some other locations, but I was just worry if the messages will cause any issues later

Please keep us posted and be careful.

I removed my Apple Watch after that incident and it has never happened again, perhaps the Bluetooth or something magnetic affect it

@dji-ken, it happened again even after I removed my Apple Watch. I'll try to turn off wifi to see if I'm getting it.

I had the same error on a 15 minute flight. And this error showed up about 2 minutes on flight and caused distance to be off on the app. When I tried to land I was not able to control the Mavic and crashed.

Here is a link the flight video log.

And I have flown from this location more than 20 times and just had this problem once.
