The Samsung Galaxy S6 has in addition to a variety of sensors, also a sensor on board, with which the magnetic north can be detected. With this magnetic sensor, you can use the Samsung Galaxy S6 as a compass. This is mainly for outdoor navigation is a very useful function, provided the magnetic sensor has been calibrated. Because unfortunately the sensor can be influenced by environmental circumstances and thus an indication of the direction is sometimes very inaccurate. To avoid that it is useful as mentioned above, to calibrate the magnetic sensor. We show you how to calibrate the magnetic sensor and therefore the compass function on the Samsung Galaxy S6 and in our article:
