About 45.3 percent of Android-based devices are currently on Froyo, Google said on its developer site. Version 2.3 Gingerbread is not too far behind, however, with 38.2 percent of devices running more current versions of the OS (0.5 percent are running 2.3 or 2.3.2).
About 11.7 percent are still on Android 2.1 Eclair. Just over 1 percent have the earliest versions of the mobile OS, dubbed Donut and Cupcake.
On the Honeycomb front, the tablet-optimized OS has yet to make any great inroads. Most, or 0.9 percent, are on Android 3.1, while 0.7 percent have Android 3.2 and 0.2 percent have Android 3.0.
The first phone to run Android Gingerbread, the Nexus S, made its debut in December. By January, only 0.4 percent of devices were running Gingerbread, with phone makers slow to upgrade. But Motorola soon started rolling out the upgrade to its Droid lineup, including the Droid X, X2, and the Droid 2 Global and Droid Incredible, and newer Android phones are coming to market with Gingerbread pre-installed, helping to boost its user base.
For Honeycomb, the first 7-inch tablet with Android 3.2, the Acer Iconia Tab A100, was released in August. At IFA, meanwhile, Toshiba unveiled its AT200 tablet, the thinnest Honeycomb tablet yet. Last month, Viewsonic also announced two new Android tablets, the 7e and 7x.
All eyes are now, of course, looking to the next Android release, known as Ice Cream Sandwich, which will combine the best of Gingerbread and Honeycomb. Google previewed Ice Cream Sandwich at the Google I/O conference in May, but recently sent out invites for an October 11 event that might include the launch of the next OS.
Android is doing well in the U.S., but could that change with the launch of the iPhone 4S, especially with the addition of Sprint? About 56 percent of U.S. buyers who acquired a new smartphone in the last three months opted for an Android device, according to data from Nielsen. Overall, about 43 percent of smartphone owners have an Android device, while 28 percent have an iPhone.
ComScore, meanwhile, said recently that Android has captured the “lion’s share” of the U.S. smartphone market, but adding Sprint or any other carrier could help Apple regain market share.
