Get Android M Developer Preview On A Nexus 5, 6, 9 And Player

Android M was introduced to the world by Google at developer I/O 2015.  This upcoming iteration of Android is going to have some core changes but not that many changes to the UI.  It looks like Android M will basically all be about system enhancements.

Device manufacturers will be adapting the Android M for their latest flagships and for some of their older devices as well.  Google will be one of the first to role this firmware for their devices, but they have also now bought a developer preview of the Android M.

Developer preview images of the Android M developer are already available for the Nexus 5/6/9 and the Nexus Player.  If you are an Android enthusiasts and you can’t wait for the complete build of the Android M, you can flash the developer preview and get a taste of it now.  In this guide, we’re going to show you how you can install Android M developer preview on a Nexus 5/6/9 and the Nexus player.
