> What's the difference between:
> Magnetometer

Exposes raw readings*, plus bias (as separate values)

*which might include fixed hardware corrections because of adjacent hardware

> GeomagneticFieldSensor, and

Exposes adjusted values from hard iron in the phone and potentially in hear surroundings - it is intended to give the vector to the earths magnetic north. which means declination and inclination as well

> GeomagneticOrientationSensor

Gives an orientation to the earth magnetic north usually adjusted to the earth plane (no actual magnetic inclination)

> Compass

Same as above, but uses GPS to find location and adjusts to the actual North instead of magnetic North.
