[android-developers] Rotation Vector Sensor - anyone using it? (issues w/ Galaxy Tab 10.1)

Hello, I am working on improving an augmented reality app I have, and part of that improvement involves making use of the sparsely-documented rotation vector sensor, which seems to integrate the magnetometer, accelerometer and gyroscope rather well on several of my devices.  This will serve to replace the classic magnetometer + accelerometer fusion + filtering that we've had to do ourselves previously.  Making use of this seems to be a huge improvement, and I'd love to deploy it as soon as I can get the feeling it will be safe for most devices.

The problem I am running into is, on my Galaxy Tab 10.1, which just got ICS 4.0.4, the Rotation Vector Sensor does not seem to be working consistently when dealing with screen rotation compensation. North seems to change places depending on how the screen is oriented, even after calling SensorManager.remapCoordinateSystem(), whereas all is good on the Nexus 7 and Galaxy Nexus, and several other gingerbread + devices, that is, North is consistent, after calling SensorManager.remapCoordinateSystem().

I haven't really seen much when doing google searches for anyone really making use of this or running into this sort of thing, so if anyone here has any experience, please get in touch.  Or, if you have some of the less popular devices which have gingerbread+ and are interested in helping evaluate a proof of concept/test APK, let me know.
