Devs can now start making Android 6.0 Marshmallow custom ROMs for Sony Xperia devices
Sony has just published Android 6.0 Marshmallow AOSP configuration and binary files for all of its recent high-end Xperia products, such as the Xperia Z3, Xperia Z3 Compact, Xperia Z2, Z4 Tablet, and many others.
The company has also added the new Xperia Z5 and Xperia Z5 Compact to its Open Device program, one that ensures that developers can run open-source versions of Android on Sony Xperia devices.
If you're a regular user, and not a developer who wants to try his luck at creating Android 6.0 Marshmallow ROMs for Sony Xperia devices, then what you need to know is that Sony has started working on Android 6.0 Marshmallow updates for some of its devices. Unfortunately, not all of Sony Xperia family members will be officially updated to the new Android version, which is where the importance of Sony's Open Device program comes into play.
Since ROM developers can now get their hands dirty at creating custom ROMs for Sony's 2014 and 2015 Qualcomm-based Xperia devices, this means that you'll likely be able to get a taste of Marshmallow through a custom ROMs even if your device is not mentioned on Sony's list of Xperia devices scheduled to get Android 6.0 Lollipop.
