iOS controlled 39.2 percent of the U.S. smartphone subscriber market in April, up 1.4 percentage points since January, while Google (NASDAQ:GOOG)-backed Android slipped from 52.3 percent to 52 percent. Android lost ground throughout the first quarter after reaching 53.4 percent nationwide smartphone share at the close of 2012: This spring, Samsung Electronics--the world's largest Android device manufacturer--released its latest flagship smartphone, the Galaxy S4, which is expected to revive the platform's U.S. fortunes moving forward.

BlackBerry (NASDAQ:BBRY) tumbled from 5.9 percent market share in January to 5.1 percent in March, but the operating system is also in line to mount a comeback in the coming months. The company did not release the BlackBerry Z10--the first smartphone running its overhauled BlackBerry 10 operating system--until late March, too late to significantly impact comScore's data.

Microsoft's (NASDAQ:MSFT) Windows Phone experienced a small decline in March, sliding from 3.1 percent U.S. market share in January to 3 percent. Symbian held steady at 0.5 percent.

ComScore notes that 136.7 million Americans own smartphones, up 7 percent since January and corresponding to 58 percent mobile market penetration. Apple leads all manufacturers with 39.2 percent U.S. market share, followed by Samsung at 22 percent, up from 21.4 percent in January. HTC trails at 8.9 percent, down from 9.7 percent three months earlier.
