Although the concept programme was initially limited to 10,000 users, Sony says that it has now released a "last minute batch of extra spaces". This means that you can also participate in the programme if you were not among the initial team.

You just need to provide information such as your email address, age and level as a mobile phone user on the mobile app to download Android 6.0 Marshmallow on your Xperia Z3 or Xperia Z3 Concept ahead of its public release.

The test is still limited to select European countries, including Sweden, Denmark, Norway, Finland, Iceland, Estonia, Latvia, Lithuania, the United Kingdom, Ireland and Germany. Also, the participation is on first come, first serve basis.

The list includes the newly unveiled Xperia Z5, Z5 Compact and Z5 Premium as well as the Xperia Z4, Z3+, Z3, Z3 Compact and the Z3 Tablet Compact among others.
