After a long wait Android 4.4.4 23.0.1.A.0.167 firmware has been certified for Xperia Z2 and Xperia Z2 Tablet. Sony first updated Xperia Z1 and Xperia Z Ultra on android 4.4.4 version and later on updated Xperia T2 Ultra family on android 4.4.3 version though it was weird that the then flagship model Xperia Z2 was left out in cold without an update.

23.0.1.A.0.167 firmware is certified for all models of Xperia Z2 and Xperia Z2 Tablet globally which clearly means the roll out is very near now. If you noticed Sony has adopted a new firmware number series i.e. 23.0.X.X.X.XXX for Xperia Z2 series now which clearly means a major update over older Android 4.4.2 17.1.2.A.0.314 firmware and may be a new UI like Xperia Z3.
