Although it is clearly an astounding number of daily activations, the increase appears to be quite steady. In August it was reported that over 550,000 Android devices were being activated daily, with a total of 150 million devices activated worldwide. In June the number of daily activations was 500,000, while in May it was only 400,000. At this rate of growth, Android is likely to hit 1 million activations per day quite soon.
With such rapid increases in activations, it is no surprise that Android now holds over 50% of the global smartphone market share.
