With 8 months having past since Google first released Ice Cream Sandwich, we are starting to see some real traction in the number of devices running the latest version of Android. According to the developer dashboard on Android.com, the current install base for ICS is sitting at 10.9%. The most popular version is Gingerbread with 64%. Gingerbread is two major releases behind, although you should keep in mind that Honeycomb was never released for phones – only tablets. If you add Froyo with 17.3% into the mix with Gingerbread, you have 81.3% of Android devices running a version between 2.2 and 2.3. A number of OEMs have promised to release updates to bring their popular devices to ICS, but after 8 months there is still a lot of waiting and very little to show.
These numbers are based on the data collected during a two week period that ended on July 2nd, and is based on the number of devices that have accessed the Google Play store in that period. These numbers may not be an extremely accurate representation of the existing user base as some users might never login and to the store. However it can be a very good indication for developers when they are looking to decide what version of Android they should be targeting with their application.
