Today marks the first day of May, and those of you that love digging into market share percentages of smartphone platforms and OEMs have a reason to be excited about the start of a new month. Research firm comScore has put out its latest U.S. mobile subscriber market share report, which covers the months from December 2011 through March 2012. Things haven't changed much since last month's report, meaning Android is still at the top of the smartphone OS heap, moving up 3.7 percent to finish March with a 51 percent share of all U.S. smartphone users. Apple's iOS was the only other platform to see a market share gain during the period, growing 1.1 percent to finish with a 30.7 percent share. Rounding out the top five is BlackBerry falling 3.7 percent to a total of 12.3 percent, Microsoft tumbling 0.8 percent to finish at 3.9 percent and Symbian holding steady at 1.4 percent.
On the device manufacturer side of things, the positions are also fairly similar to last month's standings. Samsung is the king of the OEM hill with a 26 percent market share of all mobile devices (smartphones and non-smartphones), LG finished second with a 19.3 percent share and Apple wrapped up March in third at 14 percent. In the bottom spots, we've got Motorola at 12.8 percent and HTC with a 6.0 percent share. comScore also reports that, at the end of the three-month period ending in March, 234 million Americans age 13 or older owned a cell phone, with more than 106 million smartphone users.
Again, there's not a ton of surprise in these latest numbers from comScore, with Android and iOS continuing to gobble up market share while their competitors, well, don't. It'll be interesting to check out the next couple of reports from comScore to see if the arrival of the Nokia Lumia 900 can help Microsoft regain a bit of the market share that we've watched it lose recently. Until then, you can find the latest figures from comScore at the source link below.
