According to recent figures released by Google, only 28.7 percent of all Android users are on the current version of Google’s Android OS, Android 2.2 Froyo.
41.7 percent of Android users are on the previous version, Android 2.1, whilst 17.5 percent are on Android 1.6 and 12 percent of users are still on Android 1.5.
So far Android 2,2 has been released for a number of handsets which include the Nexus One, Motorola Droid, Motorola Droid, Droid Incredible, Evo 4G, Droid X and Samsung Galaxy S.
Many of the earlier smartphones which are using Android 1.5 and 1.5 wont be able to upgrade to Android 2.2, and it seems this is a major problem facing Android, which other platforms do not have, although the recent release of iOS 4.1 for the iPhone only saw certain features brought to certain devices.
Google also announced recently that Android 2.2, really isn’t designed for tablet computers, and they are planning to release Android 3.0 in the near future, which will have a much stricter set of guidelines and make it easier for all future Android handsets to run the latest version of Android.
