Does RotationVector sensor internally use magnetic sensor to determine the final values? If yes, does it account for Earth's Geomagnetic field?
There two methods in SensorManager to determine rotation, i.e, SensorManager.getRotationMatrixFromVector and SensorManager.getRotationMatrix. Does any of these methods compensates for Earth's Geomagnetic field? If yes, which method is more accurate. If not, how can Geomagnetic field be compensated? Can it be simply adjusted by subtracting the offset in input magnetic sensor values to getRotationMatrix? How can it be done with Rotation Vector sensor?
