Google has updated the Android distribution chart which shows that version 4.0 Ice Cream Sandwich is starting to make some headway among devices in the wild. Adoption of the operating system increased by 5 percent since last month with total distribution now sitting at 15.9 percent but considering the fact that it was released more than nine months ago, the figure isn't terribly impressive.

Honeycomb accounts for 2.3 percent of all Android installations but the surprising data relates to Gingerbread as more than 60 percent of devices are still running software that was released in December 2010. Even more telling is the fact that 15.5 percent of devices are still using Froyo and 4.2 percent have Éclair installed.

Android 4.1 Jelly Bean has made the list for the first time with an introductory showing of 0.8 percent, not too bad considering the OS has only been available for less than a month and is limited to Google-branded Nexus devices as well as Motorola's Xoom tablet. It will be interesting to see how quickly Jelly Bean is adopted over the coming months.

Hopefully it won't take device manufacturers and carriers too terribly long to roll out the new OS to devices already on the market, although if Ice Cream Sandwich is any indication, that might not be the case.

Distribution data was collected during a 14-day period ending on August 1, 2012 based on the number of Android devices that accessed the Google Play store during that time frame.
