Last month, Google revealed that the newest versions of its Android OS - the 5.x Lollipop releases - were installed on 18.1% of active Android devices. That figure has grown further in recent weeks - but Lollipop is still nowhere near catching up with its predecessor.

Google's latest official figures, collected during the seven days up to and including September 7, show that Android 5.0 has grown very slightly over last month, from 15.5% to 15.9%. Version 5.1 saw a larger increase, almost doubling from 2.6% to 5.1%, giving a combined total for Lollipop of 21%.

But it's the version that came before Lollipop, Android 4.4 KitKat, that continues to rule the roost - last month, it accounted for 39.3% of active devices, and it didn't move much this month, slipping by only 0.1 percentage points. Every other version of the OS declined slightly compared with August, including 2.2 Froyo, which now runs on only 0.2% of active devices.

So eleven months after it was first announced, Lollipop is now on a fifth of Android devices, but in just a few weeks' time, Google will officially unveil Android 6.0 Marshmallow - and after that, the long wait for the new version to roll out begins again...
