Sales numbers always show gains for Android as a whole quarter after quarter. The little green robot continues to be unstoppable, and in the past few years that has largely been thanks to Samsung’s domination of the Android device ecosystem. It ruled the high-end with the Galaxy S series and cleaned up at the low end with devices like the Galaxy Ace. The newest numbers show Android still on the rise, but Samsung is faltering as it deals with attacks from both ends of the market. The Korean OEM might have to change to stay on top.
