Android 6.0 Marshmallow is out in the wild and making its way to Google backed devices running the stock build. However, its predecessor Lollipop is not down and out, especially on a platform that is known for being fragmented. Indeed, the Lollipop build from last year has plenty of room for growth in the coming months and already accounts for a sizeable amount of the Android pie.
It now accounts for 23.5% of all Android devices, making it the third most popular build at this point in time. In second place is the nearly five year old Jelly Bean with 30.2%, which only highlights the problems Google has with a fragmented software base. KitKat (itself now two years old) is the most popular build with 38.9%.
