Nothing was really missing, apart from "calibration". Since parameters for low-pass filtering (to extract gravity; hardcoded in AOSP in *WindowOrientationListener.java*) are based on real m/s^2 acceleration values, having sensor returning values too far from reality made some check functions reject rotations. I had to add my conversion, with these changes in HAL:
https://github.com/Renesas-EMEV2/Renesas-device_emev/commit/7cb1a28f4baa0cb744f1124aecade3477da87c67 Indeed, after fixing calibration, rotation is correctly propagated when I rotate device. This is for example what I get when tabelt is front.facing, in portrait orientation: V/WindowOrientationListener( 258): Raw acceleration vector: x=-7.967903, y=1.2258313, z=5.5162406, magnitude=9.768268 V/WindowOrientationListener( 258): Filtered acceleration vector: x=-7.772365, y=1.587711, z=5.426243, magnitude=9.611171 V/WindowOrientationListener( 258): Predicted: tiltAngle=34, orientationAngle=282, predictedRotation=3, predictedRotationAgeMS=349.939 V/WindowOrientationListener( 258): Result: currentRotation=0, proposedRotation=3, predictedRotation=3, timeDeltaMS=139.97, isAccelerating=false, isFlat=false, isSwinging=false, timeUntilSettledMS=0.0, timeUntilAccelerationDelayExpiredMS=0.0, timeUntilFlatDelayExpiredMS=0.0, timeUntilSwingDelayExpiredMS=0.0 Note the magnitute of about 9.8 m/s^2, which is closer to real "g", than without calibration. Magnitute was around 16 before and I was getting a lot of "proposedRotation=-1". NOTE - Home launcher screen is never re-oriented. Not sure why... But other screens (e.g. Systems Settings, do get re-oriented).
