Xbox SmartGlass has now been updated for Android.  The 1.5 release includes support for Android-based tablets 7” and larger.  This update also brings with it the same continuous awake mode that other platforms received, meaning that as long as SmartGlass is connected to the console, it will not turn off, even during intermissions of active use.  Numerous design and usability improvements are included, as well as bug patches.
