Google has released new data detailing Android distribution for the 7-day period ending on April 1, 2014, revealing that its latest operating system version – Android 4.4 KitKat – is now installed on 5.3% of all Android devices that connect to the Play Store, a significant increase from early March, when KitKat accounted for 2.5% of installations, and early February, when KitKat was installed on less than 2% of devices. However, it’s still Jelly Bean that’s the most popular operating system in Google’s Android ecosystem, with the three different Jelly Bean versions combined accounting for 61.4% of Android users.

Much older Android OS versions are still in the picture, with the new data showing that 14.3% and 17.8% of Android users are on Ice Cream Sandwich and Gingerbread, respectively. Traces of Froyo and Honeycomb are also present, although both Android versions are under 1.2% combined.

Compared to last month, all OS versions other than KitKat have declined when it comes to market share. Google is expected to release a new KitKat version soon, to fix various bugs, and launch a new Android version later this year, quite possibly alongside new Nexus hardware.
