Surprisingly a new 23.2.A.0.278 firmware has been certified for Xperia Z3 & Xperia Z3 Compact, which possibly looks Android 5.1 Lollipop update over current Android 5.0.2 23.1.A.0.690 firmware build for Xperia “Z3” series. 23.2.A.0.278 firmware has been certified only for Xperia Z3 D6653 and Xperia Z3 Compact D5833 only for the time being.

    According to, my Xperia Z3 Dual should have gotten the new lollipop (23.1.1.E.0.1) by April 1st!! funny thing is my device still running 23.0.F.1.96 firmware & still didn’t get the 23.0.1.F.0.102 which is KitKat 4.4.4 & when checking the device for updates it says: your device is up to date!!! WTF is going on????
