Owners of the Sony Xperia Z2 smartphone and Z2 tablet want to keep an eye on the notifications panel as a new 23.0.1.A.3.12 firmware is spotted online. The PTCRB are done certifying the build and it could start rolling out anytime between now and the next few weeks. Of course, since it’s just the certification stages, there’s no assurance it is coming. However, the folks over at the XDA Developers forum believe it is likely coming and with bug fixes.

Since most of the features of Android KitKat were patched in the earlier Android 4.4.2 build including white status bar icons, cloud printing, immersive mode, new location menu, full screen movie art from the lock screen and new Emoji faces, we know the latter stages of KitKat are more for enhancing the OS. Don’t expect much by the way of features.


Furthermore, the clever folks are calling this one a phone carrier network specific update since the D6502 and D6503 are the ones with the certification and both are running on the same hardware. That means this likely isn’t a global update.  If it does start rolling, it will come in as a system notification alerting you.

From there you know the drill: tap the “download now” button and when it’s finished tap the “install” option. Preferably use the WiFi network instead of the mobile data so you bypass the heavy traffic from other users installing the same update as you. Furthermore, you skip the unwanted data costs.

Please drop a comment in the section below if you do start seeing this one turning up on your device. We’d love to hear when it starts rolling and what’s inside.
