Hot on the heels of the Verizon Moto X becoming the first ever non-Nexus device to get a newer version of Android before a Nexus handset (we’re still trying to get past the shock that gave us), Google has started rolling out the Android 4.4 KitKat update (build KRT16S) for the Nexus 4 over-the-air. The three week delay since Android 4.4′s official unveiling was because of a crucial bug according to Google (though that didn’t stop the company from making the factory images available for the Nexus 4 for the buggy build), but thankfully all of that is fixed and the update is ready to bring Nexus 4 users to the chocolate-flavored land of the world’s most popular mobile OS.
Also rolling out is a bug fix update for the old and new Nexus 7 and the Nexus 10, which brings the build number on all three tablets to KRT16S as well. The factory images, new binaries, and the necessary AOSP and kernel code (for all the hard-working developers out there) are online as well – if you flashed the previously released Nexus 4 4.4 (KRT16O) factory image, it looks like you’ll have to upgrade using the newer factory image for now, as the OTA update file for the new build doesn’t seem to be available.
However, you can grab the update files for the Nexus 7s and Nexus 10 for sideloading – for the Nexus 4, even the OTA file for updating from 4.3 to 4.4 doesn’t seem to be available, so at the moment, you’ll just have to make do by repeatedly hitting the “check now” button in the Settings » About phone » System updates menu.
