I was thinking of offering this as an alternative= to customers. http://www.amazon.com/Sun-DC204WB-Slip-On-Wrist-Compass/dp/B001949J1W/ref=sr_1_1?ie=UTF8&qid=1425488514&sr=8-1&keywords=slip+on+wrist+compass
Less battery drain, and probably more reliable. ;) I tried forcing it to use these two sensors: Sensor.TYPE_ACCELEROMETER Sensor.TYPE_MAGNETIC_FIELD Before that, it was defaulting to a RotationVectorSensor if one exists. I thought, at least in the phone world, that was preferable where it exists. On Sony Smartwatch 3, it does exist but apparently not preferable. I don't know about the other devices. Anybody else have secrets to contribute?
