callibration trouble

[Sharky7487]

Heres one, I had my mavic 2 pro out yesterday, got a compass error which is my first, nothing in my pockets but couldn’t calibrate the aircraft. Then my phone rang which was in the controller. I then noticed my phone message cannot connect to my internet, forgot to switch the internet off. Once it was off a/c error gone. Radio interference when the phone was searching for a connection. I now use a different phone in airplane mode. Radio interference is annoyingly bad for stray emf.
