Two weeks shy of Google detailing the next big revision of Android at its annual developer conference, the current Android version is still struggling to make its way out to devices. Android 6.0 Marshmallow is currently running on just 7.5 percent of active Android devices that have access to the Google Play Store. The rest of the field is dominated by 2014's Android Lollipop at 35.6 percent, 2013's KitKat at 32.5 percent, and 2012's Jelly Bean at 20.1 percent. 2011's Ice Cream Sandwich still clings on to a stubborn 2 percent and the immortal Android Gingerbread (version 2.3!) accounts for 2.2 percent of Android smartphones.
