The Sony Xperia T2 Ultra is receiving a brand new firmware update via the Sony PC companion that upgrades the software to a fresh Android 4.4.3 KitKat. The Ultra gets the 19.1.1.A.0.165 build number. You can check the number by navigating to Settings > About phone > Build number after you finish installing the new software to confirm the updates success.

After an initial hiccup of calling this the 4.4.4 version on the product page, Sony informs us they made the mistake. We are calling it correctly here.

According to the official change-log posted on Sony’s support page, the T2 Ultra Android 4.4.3 comes with a great deal, including optimized memory for silky smooth performance, added stability, less bugs than previously and the latest enhancements.

We already know KitKat for patching loads of features including new Location menu, cloud printing, white status bar icons, transparent status and navigation bars, immersive mode, color emoji support, full screen album art in the lock screen and movie art. As a result the remaining stages don’t carry much weight until we start seeing the Android L software coming shortly.

Routinely, you don’t have to wait for this rollout to come in stages as a notification since it is available from the PC companion. All you need to do is log on your Windows-based computer and start installing.

The company recommends using a stable WiFi connection to avoid the traffic from others doing the same thing as you. The WiFi also provides a more stable experience resulting in less stalling and therefore not as many people need a factory reset.

You should know that a factory reset results in data loss. Always backup the market apps, phone contacts, SMS texts, music files and all other sensitive data before starting just in case you lose them. A smooth experience will not result in any data loss.

Do you happen to own the T2 smartphone? Have you already gone ahead and received the fresh OTA update on your handset? Please let us know in the comments what you think of it and how it’s working for you. In addition, report any new bugs you find.
