Android fragmentation visualized. It’s not pretty. OpenSignal:
Fragmentation is both a strength and weakness of the Android ecosystem, a headache for developers that also provides the basis for Android’s global reach. Android devices come in all shapes and sizes, with vastly different performance levels and screen sizes. Furthermore, there are many different versions of Android that are concurrently active at any one time, adding another level of fragmentation. What this means is that developing apps that work across the whole range of Android devices can be extremely challenging and time-consuming.
Compare the Device Fragmentation chart with the Brand Fragmentation chart. Android is not winning. Samsung is winning.
