Thus, the devices in Sony’s Open Device program can now run a preview build of Android M, which was available until only on Nexus devices. Of course, the preview build is mainly meant for developers, but several Xperia owners who want to flash a developer preview image can now do so freely. The Android M preview has been released for the following smartphones:
Xperia Z3, Xperia Z3 Compact, Xperia Z3 Tablet Compact Xperia Z2, Xperia Z2 Table Xperia Z1 Compact, Xperia Z1, Xperia Z Ultra Xperia E3, Xperia M2, Xperia T2 Ultra, Xperia T3
However, Sony does point out that these builds are not meant for daily usage and in order to use them, you will need an unlocked bootloader. Furthermore, you need to know that the modem and the camera have not been implemented yet. So, if you know what you’re doing, go ahead and follow the official guide from Sony’s website in order to get instructions on building the AOSP M Developer Preview and download the necessary software binaries needed for the operation. After that, you can create your test image, flash it onto your device and explore the Android M Developer Preview platform.
