Android 4.4.3 is still brand new, with only certain Nexus, Google Play Edition, and Motorola devices having received it at this point (and even within this select group, there are issues). In an incredibly odd move, however, Google has released factory images for Android 4.4.4 (build number KTU84P). At first glance, there isn’t much difference, but there of course is that little something that caused Google to release the update so soon after 4.4.3.
Both factory images and binaries have been posted for KTU84P, with only certain Nexus devices seeing the love at this time — there’s the Nexus 5, the WiFi-only Nexus 7 2013, Nexus 10, Nexus 4, and the Nexus 7 (the 2012 model, in both WiFi and mobile data-supporting flavors).
OTA updates don’t look to be rolling out to devices quite yet, though you can easily flash a factory image (we’re in the process of doing so right now). There’s no word on when other devices (such as Google Play Editions) will begin receiving the Android 4.4.4 update, and when it will start rolling out over-the-air, but yeah — here we go.
As for what’s new in the update, Sprint says security fixes. We’re assuming these security issues are fairly major to justify Google updating so quickly after the 4.4.3 release last week.
