Nielsen has Android near 52 percent of US smartphone share in Q2, iPhone ekes out its own gains

If there was doubt as to whether or not Android would soon become the majority smartphone platform in the US, that's just been erased by Nielsen. Google crossed the tipping point in the second quarter after getting close in the winter, with 51.8 percent of current smartphone users running some variant on the green robot's OS. As we've seen in the past, though, the increase is coming mostly at the expenses of platforms already being squeezed to within an inch of their lives, such as the BlackBerry (8.1 percent) and Windows (4.3 percent combined). Apple still isn't in a position to fret: it kept climbing to 34.3 percent and swung the attention of recent buyers just slightly back in its direction. The real question for many of us might center on what happens in a summer where Samsung has thrown a Galaxy S III-sized curveball at Americans and any new iPhone is likely still a few months away.
