Last month Google noted on their Android Developers blog that 83% of all Android devices run OS 2.1 or higher. A month has passed and several devices have either launched or been upgraded to a newer OS. The number of Android devices that are currently running OS 2.1 (Eclair) or higher has reached 87.4%. Breaking it down by individual OS numbers: 2.1 rings in at 35.2%; Android OS 2.2 (Froyo) is now at 51.8% and the newly released OS 2.3 Gingerbread on the Nexus S is at 0.4%.
