Android Jelly Bean is the latest version of the Operating System and the most coveted version of Android available today. However, Gingerbread still has the most coverage of Android since it is still the overwhelming majority version.
Six months after launching Android Jelly Bean, only 10.2% of all Android users are running the latest version. Android 4.0 Ice Cream Sandwich, which is also another popular release owns 29.1% of Android distribution, the last major mile stone release. Gingerbread, while it may have lost some market share, still owns 47.6% of all users, however it Gingerbread is now looking dated and pales in comparison to ICS for app developers due to it’s vastly expanded and tablet developer friendly API.
The major, and obvious, plight of Android is fragmentation and users are often stuck on lower versions of the Operating Systems. With Nexus devices in such high demand, it is hoped that non-Nexus manufacturers understand that the users want devices that will receive updates for the duration of at least two years and those updates should be timely. Of course this is an ideal world, many budget handsets sell with older OS versions simply because the handsets due not pack enough power for newer flavours.
