Android 4.0 now on a quarter of all Android devices

Android 4.0 Ice Cream Sandwich is slowly dripping its way onto more devices.

As seen over the last two weeks of October, ICS now flavors 25.8 percent of all Android devices, up from 23.7 percent in the prior month and 20.9 percent in August.

Android 4.1, aka Jelly Bean, ate up 2.7 percent of the market in October, up from 1.8 percent the previous month.

The most dominant version of Android remains version 2.3, or Gingerbread, still found on more than 54.2 percent of all Android devices. That\’s down slightly from 55.8 percent last month and 57.5 percent the prior month. Gingerbread is still king after its debut almost two years ago, though the latest number shows that its powerful grip on Android is gradually losing steam.

Android 2.2 Froyo remains a major force with a 12 percent share. The three versions prior to Froyo collectively account for 3.5 percent of the market. And Android 2.2/2.3, or Honeycomb, holds just 1.8 percent of all Android devices.

Google and its Android partners have been rolling out Ice Cream Sandwich and Jelly Bean to more phones and tablets. But the update process involves device makers and mobile carriers, so it can be a slow one.

Google is prepping to unveil Android 4.2 next month on the new Nexus 4 phone.

The latest data is based on the number of Android devices that accessed the Google Play store in the 14 days ending November 1.
