Occasionally when using google maps from my phone e.g. on a train, it will report "low accuracy" and request the figure-8 calibration
The magnetometer is mostly relevant if you donot move and want to

know, in which direction the device is oriented.
 However when you move, your direction of travel can will be computed
based on your movement - the magnetometer is then completely irrelevant
and willnot used for that.

I had an extreme case of that, I had a magnetic Qi charger in the car, you could just "chuck" the phone towards it and it would be held in place and charge ... except any map application would tend to think I was doing 180° turns while stationary at junctions, and correct itself after moving off.
But I was thinking of a train journey just last week, where GPS was struggling (I was sitting at the end of a carriage with presumably not much GPS view of the sky) and it was very keen for recalibration.
