Sony Mobile promised that the Android 4.4.2 KitKat firmware update for the Xperia T2 Ultra would arrive in July 2014 (along with the Xperia E1 and Xperia M2). Sony appears to be keeping this promise as KitKat firmware has just been certified for the Xperia T2 Ultra and Xperia T2 Ultra Dual.
The Xperia T2 Ultra (D5303) has build number 19.1.A.0.473 and the Xperia T2 Ultra Dual (D5322, XM50h) has build number 19.1.C.0.116. Hopefully, it won’t be too long before the update starts rolling – we’ll keep you posted.
