The Samsung Galaxy S6 has as actually almost all smartphones a small electronic compass integrated. This measures the magnetic currents and thus can determine the compass direction.

The following apps are able to use the magnetic sensor of your smartphone:
- Android compass
- Pinux compass
- Super Compass
You know now how to use the magnetic sensor of the Samsung Galaxy S6 as a compass.
