The previous Android version, Lollipop, went down slightly from 35.6% in May to 35.4%, but it is still the version of Android with the most installs.
KitKat went down from 32.5% in May to 31.6% in June. Jelly Bean went down from 20.1% 18.9% in the same period, while Ice Cream Sandwich dropped from 2.0% to 1.9%. Gingerbread went down from 2.2% to 2.0% and Froyo is around on just 0.1% of all Android devices.
Hopefully, new initiatives from Google like the Hall of Shame will help turn the tide.
