Back on Monday, Sprint gave its users the heads-up that a Nexus 5 update was incoming, and based on the information the carrier made available, this sure looked like the arrival of Android 4.4.3. The weird thing was, Google had yet to announce the update itself, and even the factory image download page for Nexus devices failed to reflect the availability of this new version. As of today, we’re still waiting to see confirmation of users getting this Sprint update. While we wait, more and more evidence for the release of 4.4.3 in the immediate future piles up, and the latest comes to us from Sony’s Google Play edition of the Xperia Z Ultra.
The GPe Z Ultra (which we’re just noticing dropped its “Xperia” branding when joining the GPe family – weird) shows up in a listing on the Bluetooth SIG’s database, updated just today. There it gives a software version number of KTU72.S1.3013, and that first bit there clearly corresponds to its Android build date code.
Remember, the 4.4.3 update Sprint mentioned for the Nexus 5 is KTU84, and we’ve seen signs of KTU79 for the Nexus 7. While KTU72 makes this one a little earlier than both, it’s not by much: those last two numbers stand for the particular day within the quarter, meaning that this Z Ultra build was compiled on March 14 (versus March 25 for the Nexus 5).
Granted, this doesn’t help us out with knowing for certain when Google will release 4.4.3 updates for the Z Ultra, any of the other GPe models, nor the Nexus devices themselves, we’re still interested in continuing to see signs of its impending arrival.
