Many phones get this wrong (and HTML5 implementations too). Android's documentation on getOrientation from a rotation matrix is also incomplete and ambiuguous, and there own implementation doesn't seem to follow what they document. I believe this is a poor attempt to cover there gaffe of using left-handed conventions in their deprecated ORIENTATION sensor. Here is a good blog on the topic that may be helpful: http://www.sensorplatforms.com/understanding-orientation-conventions-mobile-platforms/
