Another month, another batch of numbers from ComScore that give us a glimpse into the United States smartphone market. The research firm is out with July 2012 numbers today, and the results show market share across the mobile platforms from April 2012 to July 2012, without many big surprises. During the period, Cupertino-based Apple led in total gains. It boasted a 2-point change in overall smartphone platform (OS) market share and a 1.9-point change in total U.S. smartphone and non-smartphone sales. However, South Korea-based Samsung continued its strong lead as the world’s top handset manufacturer. It boasted 25.6-percent of the total marketshare in July 2012, while Apple held 16.3-percent behind LG. Furthermore, Android continued to lead in OS marketshare with 52.2-percent. Apple fell behind in second place with 33.4-percent.

The amount of growth could be considered a little odd for Apple, especially considering the much-anticipated iPhone 5 nearing its release (remember these numbers are from July). Apple invited select members of the media today to a Sept. 12 event where the next iPhone out of Cupertino is expected to be unveiled. A Sept. 21 release date is also rumored and could kick off what analysts think may be record-setting sales for the September quarter. You would think the slow down of sales for the iPhone 4S would contribute to a slow down in growth, as indicated earlier today:

A separate analyst note released today showed the iPhone 4S knocked off its spot as the top-selling smartphone, as it was replaced by Samsung’s widely popular Galaxy S III. The Android handset sold 10 million units during its first month on the market. Of course, we will play close attention to October’s numbers when things may look a little different.
