With the wide range of devices and active versions of the Android operating system out there, complaints that the platform is severely fragmented are justified. Fortunately, KitKat is starting to gain some ground and now enjoys an install rate of over 20% –this is a good thing. July of this year was sitting at a 17.9% adoption rate, which was a jump over June at 14.9%.
Slow and steady wins the race, so they say, and this kind of continual improvement is a more significant sign than the number itself. Understandably, older Android releases are declining, with releases like Ice Cream Sandwich falling nearly to the single digits for percentage of installs.
Which version of Android a device is running becomes significant when discussing operating fundamentals like security, it is difficult to speak about the platform as a whole when there are so many varieties running with so many patch levels. It is also important to developers trying to create apps: each version of Android supports a particular set of tools and capabilities.
By comparison, Apple boasts that nearly 90% of all devices are running their latest operating system (iOS 7).
