A new firmware update has been certified by the PTCRB for the Xperia Z2. Build number 17.1.2.A.0.323 looks like a small update, perhaps a bug/security fix, over the current build (17.1.2.A.0.314). The wait for Android 4.4.4 KitKat is set to continue for a little longer then. We’ll let you know once this new build lands.
