Sony Xperia Z may receive its official Android 4.3 Jelly Bean on Dec 19, 2013, based on the support page screenshot of the smartphone. If that's true, Xperia Z will get firmware build 10.4.B.0.569 designed for Xperia ZL, ZR and Tablet Z.

Mistaken Android 4.3 Jelly Bean?

Xperia Blog captured Android 4.3 Jelly Bean scheduled release date on Dec 19 this year based on Sony's official software update Web page of Xperia Z smartphone. It features the firmware build version 10.4.B.0.569 that was certified by PTCRB on Dec 16, 2013.

However, the official Sony Xperia Z software update page has been edited again by Sony, and this time, viewers will see Android 4.2 Jelly Bean with 10.3.1.A.2.67 firmware build released on Sept 23.

It is interesting that Sony may have made a mistake on its Web site with expected rollout date but can also mean something - a possible delay of Android 4.3 Jelly Bean release. Either way, the bottom line is the Xperia Z will get the new firmware soon after the Xperia Z1 and the Z Ultra.

Build 10.4.B.0.569

The captured image by Xperia Blog of firmware build 10.4.B.0.569 runns Android 4.3 Jelly Bean which was certified by PTRCB recently for Xperia Z, ZL, ZR and Tablet Z. The following are the Xperia models getting the newly certified firmware build:

- Xperia Z: C6602, C6603, C6606

- Xperia ZL: C6502, C6503, C6506

- Xperia ZR: C5502, C5503

- Xperia Tablet Z: SGP321.

XDA developers forum member Androxyde made the firmware available for anyone interested to update their Xperia Z C6603 and Xperia ZL C6503 to Android 4.3 Jelly Bean based on official software by Sony.
