Owners of Nexus device (barring the Nexus 6) are in for a special treat, as Google has rolled out the long-awaited Android 5.1.1 factory images for the Nexus 4, Nexus 5, Nexus 7 3G and Nexus 9 LTE, following its recent release of OTA update for the same Lollipop iteration on a bunch of these devices.
