After way too long running Android 5.0, the Google Nexus 9 by HTC is finally getting an update to Android 5.1.1, the latest version of Android. In fact, it’s getting the update before Google’s other flagship Nexus device, the Nexus 6 by Motorola.
The update weighs in at 400.7MB and includes a variety of stability and bug fixes that should hopefully get the ailing Nexus 9 up and running in tip-top condition in no time. (Many users, including me, have been suffering through increasing amounts of lag with no fix in sight for way too long.)
Now that the update is finally rolling out over the air, Google has also been kind enough to update the Nexus factory images page, in case you like to update your Nexus devices that way instead. As of publication, the factory image is only available for the WiFi version of the tablet – the LTE Nexus 9 is still sitting at 5.0.2.[Google+ | Android Police]
