As of the period ended May 4th, Lollipop 5.0 is on 9 percent of Android devices and the latest Android 5.1 is on 0.7 percent of devices.
At the end of March, that figure was still floating around 5 percent so the growth has been significant in the last thirty days or so.
Android 4.4 KitKat fell a few percentage points to 39.8 percent but remains the dominant Android OS for the time being.
