The Xperia T2 Ultra and Xperia T2 Ultra Dual are currently running Android 4.4.2 KitKat firmware, however it seems that soon enough the handsets will be updated to Android 4.4.3. The leaked screenshot below shows the latest certified firmware build (19.1.1.C.0.56) for the Xperia T2 Ultra Dual (D5322) running Android 4.4.3.
A similar build has not been certified for the single SIM version of the Xperia T2 Ultra, but it can’t be far behind. We do find it strange that, if true, why Sony didn’t just update straight to Android 4.4.4, like it already has done for the Xperia Z1, Z1 Compact and Z Ultra. We’ll let you know when the update starts rolling.
