iOS 6 Volume Knob bug?

[touchu4g]

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?

can you dumb it down a litle i dont understand.

The only thing I can think of is that it relies on the gyro, only found in the 4S, to know what angle to reflect the "light", but since you said others with a fourth generation iPod Touch have the feature working I'm not sure why it wouldn't working for you on different devices.

Edit: Disregard this, was not thinking...completely forgot the iPhone 4 had gyro and was not aware that the new iPod Touches had it as well. Sorry!

Thanks for the reply. Isn't there a gyroscope on the iPod touch 4G? I don't know why it's not working. I have gotten this to work on beta 1-2 but after it stopped. It's not a hardware problem. Maybe the people I have asked are still on beta 1 or 2.

The 4th gen iPod touch has a gyroscope, as does the iPhone 4.

Yep it does

I never understood the difference between the gyroscope and the accelerometer. I know that one measures the acceleration and the other measures rotation, but they perform pretty much the same to me...

I know that the reflective volume knob was removed from the iPhone 3GS from iOS 6 beta 3 onwards and replaced with a static knob. The iPod touch (4th generation) may have received the same treatment. I don't know about the iPhone 4 though.

I'm presuming the dynamic volume knob is either a 4S exclusive or a 4+4S only feature.

It's about accuracy and "noise". An accelerometer isn't terribly accurate, and it relies on the acceleration of gravity to figure out where down is. And all it can figure out is where down is. You need a compass as well to figure out forward and right. And when you shake it, the direction of gravity is much more difficult to figure out (if not nigh impossible). A gyro is effectively immune to these effects.

In some cases, it doesn't really matter which you use. But in others, it is night and day.
