A few days back we saw Xperia Z Ultra C6833 getting android 4.4.2 14.3.A.0.681 firmware update OTA notification on a user’s handset which was believed to be an internal leak or an update on a developer’s handset. 14.3.A.0.681 firmware screenshots revealed the new KitKat UI from Sony and other features also. 14.3.A.0.681 firmware system dump is now available for download and some apps and features have already been ported to other Xperia handsets.

Just now @latter21 from Digi-Wo, a credible source when it comes to Sony Xperia handset’s leaks and other internal info; has just posted a pic of Xperia Z Ultra C6802 running on 14.3.A.0.747 firmware which is android 4.4.2 KitKat, a build higher than what we saw previously ( 14.3.A.0.681 firmware ).

Take a look at sneak peek of Xperia Z Ultra’s latest KitKat 14.3.A.0.747 firmware build about phone details.

As mentioned by original source, there is no tap to wake up feature included. 14.3.A.0.681 firmware details revealed that answering machine and simple home launcher is included while there is no smart call handling, smart backlight control and camera apps are same like on android 4.3.

It was already known that Sony has started testing a new 14.3.A.0.747 firmware build for Xperia Z1, Z Ultra and Z1 Compact and after seeing the leaked pic of 14.3.A.0.747 firmware about phone running on Xperia Z Ultra, we can hope it may be the final build to get released, though nothing is confirmed yet.

We will keep you updated as soon we get more info on Sony’s plan to launch KitKat for Xperia Z1, Z Ultra and Z1 Compact, stay tuned till then.
