This just in: a new update will be unveiled by Sony and it will roll out for the Xperia devices. This update will also fix the Stagefright glitches that were discovered.
Even though the latter upgrade is based on the Android Lollipop 5.1.1 variant, the build number is enhanced from 546 to 23.4.A.0.580. These are the following Xperia devices that will receive the update: Xperia Z3 (D6603 variant), Z3 Compact (D5803 variant) as well as the Z2 (D6503 variant). The big release will happen in Three Austria and it will also arrive to Vodafone subbies located in Spain and UK.
So, if you live in the above mentioned area, hurry and check to see if the update is available for your Xperia device. Do this by going to Settings, click About Phone and then go to Software updates and look for System updates.
The update will not occupy a lot of space, only 2.6 MB and you will also receive a major upgrade regarding the 35 libstagefright libraries. The fix will also function on the Z-series that already work on the v5.1.1 Lollipop. Don’t worry if you recently bought a new Sony gizmo, the update will work on it too because for most Sony devices, the libraries are identical.
According to Sony’s claims, these patches came in from the titan Google and they were meant to target the Stagefright inconvenience. The patch was then rolled out to all carries and it popped-up into the basic software maintenance upgrades.
Stagefright is a pretty useful playback service, that reveals multimedia messages to its users. The glitch that was found in this service permitted hackers to get their hands on those media rights.
Important: The fix can be set-up by hand and you can check out the forum to get a pre-rooted alternative of 23.4.A.0.580 fix (available in UK Vodafone) for the Z3 Compact device.
