ComScore: Android's U.S. growth plateaus in Q2, BlackBerry in freefall


Google's (NASDAQ:GOOG) Android mobile operating system continues to dominate the U.S. smartphone landscape, but its market share lead remained unchanged from the end of the first quarter of 2013 to the close of the second quarter, digital research firm comScore reports.

Android controlled 52 percent of the U.S. smartphone subscriber market in June, identical with its March total. Android's holding pattern is particularly notable given that Samsung Electronics--the world's largest Android device manufacturer--released its latest flagship smartphone, the Galaxy S4, during the second quarter period.

Apple's (NASDAQ:AAPL) iOS continues to grow, jumping from 39 percent U.S. smartphone share in March to 39.9 percent in June. BlackBerry (NASDAQ:BBRY) tumbled from 5.2 percent market share to 4.4 percent: The manufacturer rolled out its new Z10 and Q10 smartphones during the second quarter, and its poor U.S. showing suggests the devices didn't catch fire with consumers.

Microsoft's (NASDAQ:MSFT) Windows Phone experienced slight gains during the second quarter, increasing from 3 percent U.S. market share in the first quarter to 3.1 percent. Symbian slipped from 0.5 percent to 0.3 percent: Nokia (NYSE:NOK) is halting shipments of Symbian-powered smartphones this summer.

ComScore notes that close to 142 million Americans own smartphones, up 4 percent since March and corresponding to 59 percent mobile market penetration. Apple leads all manufacturers with 39.9 percent U.S. market share, followed by Samsung at 23.7 percent, up from 21.7 percent in March. HTC trails at 8.5 percent, down from 9 percent three months earlier.
