Google has released the Android distribution numbers for the month of September, showing continued growth for Android 4.4+ KitKat. The premier version of Android saw a rise of 3.9% compared to last month figures, which now accounts for 24.5% of all Android devices available in circulation. Android 4.1+ Jelly Bean and 2.3 Gingerbread are seeing a steady decline in marketshare, which has positively affected KitKat.
The fact that Android 4.4 is on nearly 25% of all Android smartphones and tablets in the market today will certainly come as good news for Google which has been fighting the ghosts of fragmentation for long now. It will be interesting to see whether the number takes a rise and if the arrival of Android L will have any bearing on the growth of Android 4.4.
It must be also noted that the marketshare of Android 4.0 Ice Cream Sandwich has also marginally decreased, but nowhere close to being extinct just yet. Android 2.2 Froyo on the other hand is only running on 0.7% of all Android devices, so it might go out of circulation soon.
