Android Ice Cream Sandwich
Android 4.0 Ice Cream Sandwich, or ICS, was announced at the CTIA conference in Hong Kong in October of 2011. Sales of the first widely-avaliable ICS handset, the Samsung Galaxy Nexus began in November 2011 in Europe and North America.
As an attempt to unify the tablet and smartphone versions of the Android OS, Google had ambitious plans to get it on as many handsets as possible, in order to reduce the amount of platform fragmentation that has been plaguing the mobile OS ecosystem since its launch in 2007.
As of November 2012, one year after its release, ICS accounts for about 25 percent of all OSes installed on Android phones. But it pales in comparison to Android 2.3 Gingerbread, which occupies over 53 percent of the installed base and is four generations behind the current build of Android, Jelly Bean 4.2.
OEMs have struggled to update Gingerbread-based dual-core handsets and tablets to ICS, taking as much as a year to do so, and some, such as Google's Motorola Mobility division have even had to abandon their efforts due to the technical complexities involved.
As if this wasn't bad enough Jelly Bean, version 4.2, has been on the market since late summer and is already in the crosshairs of OEMs looking to release new handsets and tablets. Like version 3.0 "Honeycomb" before it, ICS it seems was a yet another transitional operating system release with a limited lifespan.
