Its growth appears to have stalled, but Android 1.5 is still the most widely used firmware version for devices that access the Android Market. Google’s latest platform version breakdown comes only weeks after the latest report which was their first since the Droid received Android 2.1.
The newest firmware Android 2.1 jumps up to 32.4% of devices, while Android 1.6 dropped to 29.4%, and Android 1.5 was down to 37.2%. Even though Android 2.1 might not be the leader, it was the only version to increase while the others fell.
This report should look drastically different next month as many first generation phones upgrade to Android 2.1. It looks like Android 2.2 will be coming as well, so we might return to four major versions for a period of time.
Finally, it is interesting to note that only 0.6% of devices remain on Android 2.0.1. These are Droids that have not been upgraded to Android 2.1, but Motorola should be proud they achieved such a high rate updates. A recent leaked document from Sprint revealed that up to 90% of their Samsung Moment’s were running a non-current software version.
