Supposing you've got a Nexus device in your possession, you know the thrill of getting an Android update. Not just any Android update, one that brings a full extra digit to the tens spot after the five. This isn't a new desert - it's a .1 for your Lollipop. Google has begun posting Android 5.1 Factory Images for Nexus devices of all sorts this week, and that includes Nexus 5, Nexus 7, and Nexus 10, too. While we've not yet seen the Nexus 9 appear on this list, nor the Nexus 4, we'll expect at least one of the two to pop up soon.
