The Android rotation vector sensor output is provided relative to magnetic north, see https://developer.android.com/guide/topics/sensors/sensors_motion#sensors-motion-rotate.
We should either update the output metadata or properly convert to a rotation relative to true north by accounting for magnetic declination.
