Google has always done a very good job of getting their users to upgrade to new versions when upgrades are available. That, plus the fact that newer devices are running on updated versions of the Android software means that more than 60% of their users are running on Android 2.2 or higher such as unlocked Samsung Nexus S Google Black. In fact. A vast majority of their users are either running 2.3, or 2.3 which seems to be the most popular option for new smart devices that have come out in recent months.
Most devices are currently being upgraded to either 2.2 or 2.3, and with version 3.0, Gingerbread right around the corner you can exact many new devices to be released for that version of the operating system as well. Android 1.6 still has 4.8% of the user base, while Android 1.5 still has 3% of the total user base.
Google also announced in a recent press release that they are activating more than 300,000 new phones per day. A number of these devices will be making their way to the Canadian market here soon, and users can expect these devices to run on Android 2.2 or higher when the release time comes.
This just goes to show how adept Google has become and getting their users to upgrade to new versions when the upgrade is available for all of the new features offered. Comparatively,Apple updates have done well as well such as in unlocked iphone 4, but have not seen the same level of success that Google has seen. There are going to be many new devices coming out in the future that are highly anticipated, running on Google Android 2.2 or higher, so expect these numbers to continue to climb here in the future as well.
