Sony on Monday announced that it has released the Android M Developer Preview for some of its Xperia devices, and for developers who are enrolled in its Open Device program. That means, potentially, you can get the new operating system up and running on your device, even if you don’t own Google’s Nexus 6.

Keep in mind that Android M is still very much a work in progress ahead of its full launch, likely sometime this fall, and Google doesn’t recommend you install it on a daily driver. Sony feels the same way, and said that it’s mainly built for folks to prepare for the full Android M release and to “test and verify apps on the new platform” Specifically, Sony said that “it’s important to note that the AOSP software is not certified or intended for regular use,” and that “it’s only available for devices with an unlocked bootloader and comes with some limitations, for example, the modem and the camera are not implemented.”

The release is available for devices supported by Sony’s Open Device program, which includes the Xperia Z3, the Xperia Z3 Compact, the Xperia Z3 Tablet Compact, the Xperia Z2, the Xperia Z2 Tablet, the Xperia Z1, the Xperia Z1 Compact, the Xperia Z Ultra, the Xperia E3, the Xperia M2, the Xperia T2 Ultra and the Xperia T3.
