A high degree of fragmentation is a problem that Android app developers have had to deal with since day one. KitKat, the latest iteration of Google’s dessert-themed Android updates was supposed to change that. It was designed to be more compatible with low-end devices in order to get it to more devices more quickly.
Thus far, it doesn’t seem to have worked though: according to Mixpanel less than 10% of Android devices are currently running KitKat, which was released in October 2013. By contrast, iOS 7, released in late September has been adopted by 85% of iOS users and even iOS 7.1, released as late as March, has a significantly higher adoption rate (42.77%) than Android KitKat.
