The Sony Xperia Z2 series is witnessing PTCRB certification for a fresh Android 4.4.4 KitKat, namely 23.0.1.A.3.9. It’s the second time we noticed the 4.4.4 number come out, but the first generation didn’t stick well with the device manufacturer and phone carrier networks. In addition to the D6503 smartphone, the Z2 tablet with the SGP-521 model number has a build with the same aforementioned number. To view both variants with the same number is a positive sign, as it suggests they want to push this one out to owners.

As you know, that doesn’t mean you are seeing this one rollout OTA just yet since the PTRCB certification and staged rollout are two separate things. However, it’s the final stage of KitKat have been waiting a long time for and we are predicting this build to stand and see the light of day.


Owners of these handsets have a great deal to look forward to February early next year since the Android 5.0 Lollipop is coming their way. Until then there’s still a couple of months in between and hopefully the end of the chocolate variety can satisfy fans until then. Since this isn’t the release yet, we don’t know what features are coming. There is no change-log until the day it comes out. However, we know this number for coming with Google security patches, bug fixes and a revamped phone dialer.

While most are happy with the current version of 4.4.2, it would mean no “remote play” until four months from now and that’s too long a wait for many people.
