Occasionally when using google maps from my phone e.g. on a train, it
will report "low accuracy" and request the figure-8 calibration, I think
it can use the magnetometer better to sense the direction of travel?
The magnetometer is mostly relevant if you do *not* 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 will *not* used for that.
