The Android 4.4.2 KitKat firmware update has been certified by the PTCRB for a number of Sony Xperia devices including the Xperia Z, Xperia ZL, Xperia ZR and Xperia Tablet Z. The same firmware build (10.5.A.0.227) has been certified across all devices, this is the same firmware that leaked recently for the Xperia Z, so there is no question this is KitKat. Also the date of the certification means that the firmware should be on track to launch in May 2014, which was Sony’s release date. We’ll let you know once it starts rolling.
