comScore surveyed more than 30,000 U.S. mobile subscribers for the report.
Not only did Android have 50.1 percent of total smartphone market share, up from its 46.9 percent in comScore's last report in November of 2011, that 3.2 percent rise was more than double Apple's 1.5 percent rise during the same timeframe, to 30.2 percent.
Samsung was the top handset manufacturer overall with 25.6 percent market share (that includes both smartphones and non-smartphones). However, that number was flat from November 2011, while Apple gained 2.3 percent to 13.5 percent overall, in third place. LG dropped 1.1 percent to 19.4 percent in the No. 2 position, while No. 4 Motorola dropped 0.9 percent to 12.8 percent and No. 5 HTC rose 0.4 percent and 6.3 percent.
However, comScore tracks installed user base, not new handset sales. Last week's Nielsen report showed similar numbers among "all smartphone owners," but in terms of recent purchases, within the last three months, Nielsen's data showed that the iPhone 4S fueled an Apple surge that cut Android's 16-point lead over the iPhone to 5 points.
This comes despite a recent report that indicated that the iPhone was outselling all Android models combined at AT&T and Sprint, and was even with Android at Verizon.
