You may remember Sony releasing a working AOSP builds for the Xperia S last year, well the story repeats itself now with their latest flagship device. – The Xperia Z!
The Xperia Z can now taste the latest stock flavor of Android 4.2.2 Jelly Bean, this is basically not only a huge contribution to the developer community but also aims to further facilitate contributions to the Snapdragon S4 Pro (MSM8064) SoC. This is essentially a wip developer preview and is in no way suitable for daily use but most core features are working. This includes WiFi, Bluetooth, sensors (partially) and SDcard mounting.
The camera and modem are also working flawlessly but the proprietary code hasn’t been published so it may take a while for them to be made accessible. Those two won’t work but Sony is expected to publish the full sources on Github in the coming weeks.
Sony’s aim is pretty straight forward, they’re willing to replace some of their binaries with fully open source code. This once again proves Sony’s commitment to open their software sources (at least a huge part of them).
