Is there a way to calibrate the g sensor on the xoom? I notice that some of the apps I have are way off or backwards such as a level is backwards ( tilt right and the bubble goes left etc.) and the live weather wallpaper I have the grass moves with the direction you move the phone/xoom and on the xoom it is leaning right and the water is pooled on the right hand of the screen. Where on my phone it is working the way it is suppose to be.
