Hi MacRumors. I have an iPod Touch 4G on iOS 6 Beta 4. There is a small feature that when you tilt your device on the Now Playing screen in the Music app, the volume knob changes the knob from where the light is "reflecting". This is not working for me on my iPod touches both on iOS 6 beta 4. My fathers' iPhone 4S is on iOS 6 beta 4 and it works for him. How come it doesn't work for me as for some people I have asked on other forums has said that it works for them. If you have an iPod Touch 4G on iOS 6 beta 4, does it work for you?
