Android's leading share of the U.S. smartphone market remained virtually unchanged over the last three months, increasing just 0.6% to 51.6% as of June, according to the latest comScore data. The surging growth the Google platform saw in 2010 and 2011 has stalled out this year with Android reaching a majority of smartphones. Whether the strong sales of the recently released Samsung Galaxy S III will give Android renewed momentum won't be clear until third quarter quarter figures are released.

Apple's iOS picked up 1.7 percentage points to increase to a 32.4% share, while RIM's BlackBerry platform continued to lose ground, dropping 1.6 points to 10.7%. Microsoft's Windows Phone came in at 3.8%, and Symbian, 0.9%.

Among manufacturers, Samsung's share remained roughly the same for the three months ending in June, dipping from 26% to 25.6%. LG had 18.8%, Apple (15.4%), Motorola (11.7%), and HTC, 0.4%.

Looking at mobile content use, three-quarters of mobile users sent text messages, and more than half used downloaded apps as well as used a browser. The share of people listening to music increased 2.3 points to 27.6%--the biggest jump among mobile content categories tracked by comScore.
