The tablet variant of the Sony Xperia Z2 SGP521 LTE is starting to see a brand new version of Android 4.4.2 Kitkat firmware namely 17.1.2.A.0.314 arrive over the air to selected devices. The new software update comes in phases so it doesn’t reach all owners at the same time. If you choose to skip the notification you have to go to the Settings > About phone > Software updates > Check for software updates that way. It will not come back as a system notification twice.

Comparatively, those who own the WiFi SGP512 and SGP511 models have to wait a while longer as there is no official word when the same upgrade is expected to come to you.


After you install the file it will give an enhanced touch performance, enhanced battery charging, stability improvements and more. There’s a rumor that it also gives camera improvements coming from a loyal reader. It comes for the model number SGP521 and has the processor info of Qualcomm MSM8974PRO-AB. The baseband version is 8974-AAAAANPZQ-00015-10 and the kernel version is 3.4.0-perf-g35f9635, Wednesday July the 2nd just before midnight.

In addition, Android 4.4.2 is well-known for providing users with cloud printing, white status bar icons, color Emoji support, new Location menu, landscape keyboard improvements for typing, transparent status and navigation bars, immersive mode and more subtle changes to things such as revised TouchWiz UI, Samsung native app updates, performance boosts and more.

Try to install the new firmware build using a stable WiFi connection and not the mobile data plan. Data plans tend to be more expensive and don’t offer as much reliability with the connection. If it drops out halfway through it can cause problems that may lead to requiring a factory reset. Resets can result in data loss. With that in mind, its a good idea to make backups of the market apps with Helium, contacts, photos galleries and other sensitive data.
