Is there a New sony Xperia Z firmware (10.3.1.A.0.236) soon?....actually The Sony Xperia Z version (C660X) may soon be receiving a new firmware upgrade judging by a thread on xda-developers. A poster who has a"brown" developer device says that he has received a new update in the form of build number 10.3.1.A.0.236. This Special Android 4.2.2 version has not been certified on the PTCRB website so far, the latest current firmware is 10.3.A.0.423.
Whether this Special firmware version makes it to used devices is unknown right now, as it is likely to be a test version. Even if it doesn’t, it shows that hopefully a new firmware update is on its way soon for Sony Xperia Z devices.
