Google's latest mobile operating system, dubbed Ice Cream Sandwich, is now on 0.6 percent of Android devices, according to stats released yesterday.
About 0.3 percent of devices are running Android 4.0-4.0.2, while the other 0.3 percent are on Android 4.0.3, Google said on its developer Web site.
At this point, however, the most popular version of Android is Gingerbread, or version 2.3. About 55 percent of devices currently run that version of Android, followed by its predecessor, Froyo, with 30.4 percent.
In early December, 50.6 percent were running Gingerbread while Froyo was on 35.3 percent of phones.
Android 4.0 Ice Cream Sandwich was first announced at a joint Google-Samsung event in Hong Kong in late October, and Google released the OS's source code about a month later. The first device with ICS, the Samsung Galaxy Nexus, made its debut overseas on Nov. 17, with the U.S. version on Verizon Wireless following suit on Dec. 15.
Ice Cream Sandwich pulls in elements from Gingerbread and the tablet-centric Honeycomb OS, or Android 3.0. At this point, Honeycomb is still on a limited number of devices—3.3 percent across all versions.
There are still a few people on the earliest versions of Android, meanwhile. About 0.6 percent are on Android 1.5 Cupcake, 1.1 percent are on Android 1.6 Donut, and 8.5 percent are on Eclair, or Android 2.1.
Recently, Google's Android chief, Andy Rubin, said there are more than 700,000 Android device activations each day.
