Missing SensorCore with Cyan [Lumia 521]

Got Cyan recently on my 521 with PfD 8.1.1, but many features unavailable, like brightness slider, USB options, equalizer etc. But why no SensorCore?

It looks like that feature is only available on newer devices. Nokia's SensorCore opens up Windows Phone to health and fitness apps galore | Windows Central
