Sony had announced early this month that an Android 6.0 Marshmallow preview update will be rolled out to randomly selected 10,000 lucky Xperia Z3 and Z3 Compact users. And it’s only been just a few hours after the build has been rolled out to those few lucky ones.

Xperia Z2 and Z3 series are going to get Android 5.1.1 update this month

Sony has mentioned that the preview build will be rolled out incrementally in the coming weeks, so there’s no need to panic in case your Xperia Z3 or Z3 compact hasn’t got the beta yet. Furthermore, Sony said that it will announce any new features as they will be added to the beta build. Sony has also stated that it has made some secret spaces available, which directly means that if you act right now and download the app named “Sony´s Concept for Android” from the Play Store, you will be able to test out the new beta update.

In order to join the test-run, you need to be an owner of an Xperia Z3 or Z3 Compact in any of these countries: Norway, Sweden, Finland, Denmark, Iceland, Latvia, Estonia, Ireland, Lithuania, Germany, and United Kingdom. It is important to remember that this update is just a preview and not a full-fledged Marshmallow upgrade and is meant to showcase how Sony’s UI will look like with Android 6.0.
