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. -- Arno Welzel https://arnowelzel.de
