Google officially introduced the latest KitKat version of its Android operating system in October last year, and despite three months passing, it continues to be installed on less than 2 percent of all active Android devices worldwide, according to new data. KitKat is installed on 1.8 percent of all Android phones or tablets that log in to the Google Play store; that’s a small increase on the 1.4 percent that it charted in January. Jelly Bean — the precursor to KitKat — saw its figure rise to 60.7 percent from 59.1 percent the previous month. Particularly of note is the fact that the newest Jelly Bean build — Android 4.3 — rose from 7.8 percent to 8.9 percent over the past month. Looking at the most significant of the rest: the ratio of devices running Ice Cream Sandwich dropped from 16.9 percent to 16.1 percent.
