Sony continues to impress by how well they take care of their customers and extend transparency toward their Android update process. They just invited 10,000 Xperia device owners to beta test the Android 6.0 Marshmallow update.
Right now, this beta test is only for folks who own the Xperia Z3 or Xperia Z3 Compact. All other Xperia devices need not apply just yet. This means the Xperia Z3+ was also excluded. Perhaps there is something different enough in the hardware of that device that Sony needs to work on Android 6 a bit longer before a full blown beta test.
For more details on this program and how to sign up to be one of the 10k customers assigned to the beta test, just check out this link here: Sony’s Concept for Android™: Marshmallow edition | Sony Smartphones
