Sony's Xperia Z3 is one of the first non-Nexus device to support the Android N Developer Preview. It was previously rumored that Google would allow other manufacturers to begin testing the software, and that appears to have proven true. You will need to flash the first image (of Developer Preview 2) and then Sony will push future updates over-the-air to the phones.
So, if you happen to have a Xperia Z3 laying around, and want a taste of the latest operating system before it is officially available to everyone, you can give it a go now.
