I’m able to output the tilt, etc. with 4.3 on iOS using both the PlayerController->GetInputMotionState and the PlayerController->GetInputVectorKeyState. However, as soon as a touch event is registered, all returned values are zeroed. I haven’t figured out how to re-enable them; it appears the touch input cannibalizes the motion input.
Edit: I was wrong. I had an invisible Touch Interface that was (probably) colliding with the GetInputMotionState results. After clearing the touch interface, I’m able to get consistent tilt data from PlayerController->GetInputMotionState.
