Google revealed that more than one-fifth of devices visiting its Play store in the fortnight to 4 September 2012 were running Android 4.0 (Ice Cream Sandwich), as penetration of this version of its OS grew.

The growth, to 20.9 percent, is an increase from 15.9 percent in the period to 1 August, and from 10.9 percent in the period to 2 July.

The biggest single version of the platform remains Android 2.3 (Gingerbread), although this has now dropped below the 60 percent mark – all versions of this accounted for 57.5 percent of visits during the period.

The latest release, Android 4.1 (Jelly Bean), accounts for just 1.2 percent of visits, largely due to the currently limited device support.

The company noted that the majority of devices visiting fell into the “normal” screen size category (between three inches and five inches). The most common screen resolution was what Google defines as “high” density.

In total, 51.9 percent of visits were from devices with “normal” screens and “high” densities.
