As of a week ago, there have been new numbers and Marshmallow has started catching up with its older brothers. Last month, it finally made past 15% of the mass android smartphones, with Lollipop and Kitkat still leading the numbers, but as you can see, not for much long.
The older versions(Froyo, Gingerbread and ICS) are almost long gone but Jellybean still holds a large chunk of the mass and that is combined jellybean of course(4.1, 4.2 and 4.3). As Jellybean, Kitkat and Lollipop still get the latest out of playstore with the help of updates, they are still usable but as Android 7.0 Nougat releases, it'll change everything. Although it still take ages for people to update their phones as most people don't prefer Nexus so fingers crossed for that one.
