Sony's relationship with "pure" Android is an interesting one. As a company they generally make it easy to root or otherwise modify their phones or tablets, with a few notable qualifiers. The AOSP for Xperia project, which provides the basic tools for building standard Android ROMs on popular devices, is also one way that Sony stays relevant for those who buy phones with the intent to add aftermarket software. Today it gets two new flagship options, the older Xperia Z1 and Z2.
Sony has announced that the latest version of KitKat is now rolling out to many of its Xperia products with Z in their name. That includes the Z, the ZL, the ZR, and the Tablet Z. For the confused, no, I'm not talking about smearing chocolate all over a Wii U controller. Sony just really likes the final letter of the alphabet, and it's now delivering Android 4.4.4 to four devices all bearing Z in their names.
Update: Xperia Blog has confirmed this update is, in fact, Android 4.3. I can confirm that T-Mobile does, in fact, suck at changelogs. The version has also been tweaked to 10.4.C.0.814.
It might not be the latest and greatest anymore, but the Sony Xperia Z on T-Mobile is still getting some update love today. That mysterious Android 4.3 update that was pulled a few months back still isn't back, apparently. Instead, you get some small tweaks.
Do you use a Sony Xperia Z? Did you buy it from T-Mobile? Then check that Settings menu - according to this T-Mo support page, you're getting a taste of Jelly Bean 4.3 starting today. Of course these things tend to go out in waves, so those without patience can follow the links on T-Mobile's site and manually download and flash the new software (10.4.C.0.797) using the Sony PC Companion software.
Typically Christmas day is a slow one for technology news, but apparently the good folks at the Android Open Kang Project have dragged their coding machines in front of the open fire. Today AOKP has posted the first nightly builds of Android 4.4.2, granting deliciously fresh custom ROMs to all the good little girls and boys. And all the bad ones too, I suppose.
The list of initially-supported devices doesn't cover AOKP's official support list yet, but it covers most of the major Nexus devices, Samsung's Galaxy SIII and S4 American and international incarnations, all five major versions of the HTC One, and a handful of Sony devices (because they tend to be pretty open as far as bootloaders and modifications go).
While the Nexus elite have since moved on to KitKat, there are still a lot of devices just getting by with some flavor of Jelly Bean. At least Sony is keeping its promise of updating devices to the latest version of that sweet-themed platform. Android 4.3 is beginning to make its way to the Xperia Z, Xperia ZL, Xperia ZR, And Xperia Tablet Z.
OmniROM has only existed for a few weeks, but it's already gaining traction with certain groups (you know who you are). The first nightly builds of OmniROM based on Android 4.4 supported 15 devices, and today brings six more to the fold.
If you're using the T-Mobile variant of the slick Sony Xperia Z, check your notification tray - you might have a very welcome waiting for you. According to this T-Mobile support page, the Xperia Z is finally getting an over-the-air update. It's probably not what you were hoping for: the update brings the phone up to Android 4.2. You know, the version that's now over a year old.
If it makes you feel any better, it's been only five months since the Android 4.2 update was sent to the international version of the Xperia Z.
