Backport GAME_ROTATION_VECTOR on Android < 4.3

Hi,
we are working on a Android app that needs to make use of the sensors to guide the user through what can be described as a panorama style of UI.
We need to track vertical and horizontal rotation.

For Android 4.3 we have been using the new GAME_ROTATION_VECTOR sensor and it works very well. The reason for using GAME_ROTATION_VECTOR sensor is that the ROTATION_VECTOR sometimes just starts to spin and apprently starts to self calibrate the compass or something. A problem that seems to be specifically addressed by the GAME_ROTATION_VECTOR sensor.

Now: Is there a way to backport the GAME_ROTATION_VECTOR to Android <= 4.2? Is it possible to do the fusion in the APK and apply the same filtering as is done in the GAME_ROTATION_VECTOR?

We have tried to do the fusion in the APK and that works, but only as good as the 4.2 devices. We still have the issue that sometimes the magnetic data changes drastically, making the "world spin".
