Here's a minor surprise: Android slipping at all in US market share. Although it saw just a tiny drop of two tenths of a point from where it was in March, and still saw a gain over January, Google's platform was down to 50.8 percent in April. Nothing dramatic enough to make Mountain View worry, as such, but definitely a sharp break from the rapid growth of last year. Apple could meanwhile claim a small victory for the month as a result by continuing to grow -- even if we wouldn't call its 31.4 percent iPhone share a revolution. Of the other platforms, only Microsoft had anything to crow about, as the Lumia 900 launch brought Windows Phone back just over the four percent mark.
The positions among individual cellphone makers as a whole didn't budge in April, and whatever losses came to Android's partners in that area were spread evenly across top-dog Samsung as well as LG and Motorola. Perhaps the biggest twist was HTC holding its ground at a steady six percent, which hints that the HTC One S' arrival at T-Mobile might have been just the ticket to keeping Taiwan in the fight.
