Research firm comScore conducted a survey and found that Android users accounted for 50.9 percent of the U.S. smartphone market while iOS accumulated about 31.9 percent. Results of the study came from the MobileLens service, which surveyed 30,000 mobile subscribers during the months of March, April, and May. While the Android platform and iOS platform are the leading competitors among smartphone providers, new data suggests that Apple is outpacing Android these days. The comScore data shows that there are two iOS customers for every one Android customer over the course of the last three months.

Both companies made strides but Apple more than doubled Android’s growth during the last three month period. Google’s Android gained 0.8 percent during these months while Apple’s iOS gained 1.7 percent.

RIM came in third place during this three month period with a share of 11.4 percent, which is a 2 percent drop from the beginning of February. The Blackberry makers continue to struggle and undergo internal restructuring. Microsoft’s share grew 0.1 percent and finished in May with 4 percent of the market. Finally, Symbian OS came in fifth, finishing with an impressive 1.1 percent share, dropping 0.4 points.

The findings showed that smartphone owners account for 110 million of the 234 million users aged 13 or older who use mobile devices. At the end of May, the number increased 5 percent from February and this number is steadily increasing. Samsung takes the cake, though, as it holds a 25.7 percent share of the market, up 0.1 percent from the last report. Apple, however, continues to show growth on the newest iPhone 4S, and grew 1.5 points, taking 15 percent of the entire market.
