Google: 12.4% of Android devices now run some version of Lollipop
Android fragmentation data June 2015
Android 5.1, the latest version of Google's mobile operating system is installed on just 0.8% of all Android devices. With only a few exceptions, Nexus devices are the only ones currently rocking Android 5.1 Lollipop, although that's set to change over the course of the next couple of months. The 5.0 version of Lollipop, on the other hand, is much more popular, with a share of 11.6%.
Although its share has dropped over the past couple of months as more devices get updated to Lollipop, Android 4.4 KitKat remains the most popular Android version, with a 39.2% share of the Android pie. JellyBean, which is the name given to Android versions 4.1, 4.2, and 4.3, comes in second, with a share of 37.4%.
