Google has released a new report highlighting the levels of 'fragmentation'within the user base of its Android mobile OS across the range of currently available Android-based smartphones, Information Week reports.
The study shows that the Android version 2.1, code-named 'Eclair', now runs on almost 60 per cent of all Android devices, a rise of 4.2 per cent compared to last month.
Android 1.6 - 'Donut' - accounts for 20.3 per cent of Android smartphones, and Android 1.2, known as 'Cupcake' is installed on 15.3 per cent devices.
The recently launched Android 2.2 'Froyo' can be now found on 5.5 per cent of Android devices, up from 3.3 per cent last month.
The rise in the deployment of Android 2.2 is said to be because companies are rushing to provide the firmware update for all Android devices used on their networks.
Starting with Google, which provided the Froyo update for Nexus One, wireless service providers, such as Sprint and Verizon Wireless, have been rolling out the operating system update across their networks.
The company wrote on the Android Developers Community blog that the new metrics were based on Android devices accessing the Android Market store during a 14-day period ending August 2.
