Ready for some hardcore smartphone market share numbers? ComScore's got 'em for the three-month period ending in May 2012, and you probably won't be terribly surprised by the outcome. First, let's tackle smartphone platforms: Apple and Google posted minor increase month-over-month at 0.5 and 0.1 percent, respectively (1.7 and 0.8 over a three-month span). Microsoft (consisting of Windows Phone and Windows Mobile) didn't budge between April and May, though it nudged up a tenth of a percentage point since February. RIM dropped 0.2 percent over one month, but it already experienced a much more painful sting -- 2.0 percent -- during the three-month period. Symbian also went through similar concerns, going down 0.2 percent month-over-month and 0.4 percent since February.
As for specific manufacturers, Apple once again comes out on top, adding 1.5 percent to its customer base over the last three months for a total of 15 percent share. Samsung, still leading the pack in total market share at 25.7 percent, only grew by 0.1. Given the OEM's success in deploying the Galaxy S III to every major US carrier, we suspect that number will spurt up even higher over the next quarter. Among the companies losing share: LG, Motorola and HTC, losing 0.3, 0.8 and 0.2 percent, respectively.
