Sony is currently working on a new concept build for Android which could replace their current skin for their Xperia devices. They are currently running a beta test in Sweden. They will be inviting users into the program soon if they live in that region.
The beta will be running from July 27th to September 13th of this year. You’ll only be able to test the software if you are using an Xperia Z3. Note, the Z3 Compact will now work for this test. Once the beta test has come to an end, the testers will be able to restore their devices to the current Xperia software.
