After officially rolling out for the Nexus 7 (2012) a few weeks back, it seems both the Nexus 7 2013 (WiFi) and Nexus 10 should be receiving Android 5.0.2 any minute now. Google has posted the factory images for each of the devices via their Factory Images page and as it so often goes, a rollout is expected to should follow shortly behind.
Feel free to either download and manually install via the links below (and erase everything on your device), or simply wait for the impending over-the-air update to begin. If you do take the “wait and see” approach (often times updates can cause unforeseen issues on devices), see how others are taking to the update by visiting the Nexus 7 2013 forums or the Nexus 10 forums for further insight.
