Official Android 4.4.4 KitKat is now available for Sony Xperia Z1, Xperia Z Ultra, Xperia Z1 Compact and Xperia T2 Ultra. Based on Sony Mobile support pages, the new firmware contains several exclusive features such as App to SD card, camera upgrades and latest app versions.
App to SD Card Transfer
By default, Google removed the "App to SD card" transfer on Android KitKat OS which was included to previous Android versions such as 2.3 Gingerbread, 4.0 Ice Cream Sandwich and 4.1 to 4.3 Jelly Bean.
But XperiaBlog noticed something different on the Android 4.4.2 KitKat update of Sony Xperia T2 Ultra and T2 Ultra Dual released by the company. According to a screenshot, both devices which have been updated to the said firmware version regains the "App to SD card" feature that allows certain applications to be moved again to the external storage capacity.
The feature is found at its usual location accessible by going to Settings > Applications. Moreover, Sony Mobile added a new column under the Applications Manager labelled as "On SD card" indicating that users can now transfer apps. In this way, both Xperia T2 Ultra and T2 Ultra Dual can make more rooms on the internal storage by moving selected apps to the SD card.
However, this feature seems not to appear on the Android 4.4.2 KitKat firmware update for the Xperia Z series. It is unknown why Sony Mobile did not include the feature on Xperia Z series and the possible reason right now would be the limited internal storage among mid-range and low-level smartphones.
Sony Mobile upgraded the camera performance of Xperia Z1, Xperia Z Ultra and Xperia Z1 Compact on Android 4.4.4 KitKat. According to their official software support page, these smartphones received "updated and improved camera experience." But the company did not reveal the exact type of improvements added to the devices.
Most Xperia smartphones which have been updated to Android 4.3 and Android 4.4 are using Smart Social Camera app that allows downloadable camera add-ons such as Info-Eye, Timeshift Burst, Motiongraphy and Augmented Reality.
Optimisations on the camera may include faster loading time, better image capturing, improved low-light scene detection and other related changes.
