It seems that three months since its release, the adoption of Android 5.0 Lollipop seems to be unprecedentedly slow.
Still, as can be observed from the graph below, three months into its existence KitKat somewhere around 2% was already present in a significantly higher number of devices than Lollipop currently is.
Compared to previous major upgrades of Android, Lollipop is quite big. It renews the UI design (Material Design) from Holo which has been in use since Android 3.0 (2011), it features a new ART runtime that replaces Dalvik which has been in use since, the beginning and it also has support for 64-bit devices. Lollipop is brand new in many ways, and I thought that Google would try very hard to drive quick adoption.
This clearly hasn’t been the case. I strongly doubt that this was intentional.
A bit worrisome.
