The latest build of Google’s mobile operating system — Android 6.0 Marshmallow — is just around the corner. It has already started rolling out to miscellaneous Android One handsets and will be hitting the Nexus 6 and Nexus 5 very soon. As we know, various manufacturers do take their time to update their relevant smartphone models to the latest Android build – after all, their proprietary UI skins and phone-specific apps take some time rehashing and testing.

However, Sony fans may have a chance to test the Marshmallow build for Xperia early – so long as they own an Xperia Z3 or Xperia Z3 Compact, that is. As a part of the Sony Concept for Android initiative, the company will let 10,000 enthusiasts try its new interface ahead of launch.

Sound exciting? In order to participate, one must be located in one of these countries: Sweden, Denmark, Norway, Finland, Iceland, Estonia, Latvia, Lithuania, United Kingdom, Ireland, or Germany. If that’s the case – download the “Sony’s Concept for Android” app, linked below, and register. All that’s left then is to wait and hope that you were among the first 10,000 people to do so.

The Z3 and Z3 Compact are just a small portion of Sony handsets that will be getting the Android 6.0 update. Check out this article for the full list.

Foaming at the mouth to try this out? Well – good luck!
