Once you confirm that your device has a compass included in your device, please ensure that Sensor Mode is set to ‘Auto’ in the app.

This can be done by pressing the mini-compass button on the bottom center of the screen or by going to Menu > Settings > Sensors.

Once set to ‘Auto’, point the device (back portion) to the sky to activate the Sensor Mode.

Note: Please ensure that there are no magnets or metal pieces near the device. These objects interfere with sensors and are usually found on device protection covers.
