We're so used to constant flux in smartphone market share that it's a surprise when things don't move. Yet that's what we're facing today. ComScore found that the US smartphone field in September was virtually unchanged from where it was in August, even down to smaller players like Symbian and Windows Phone. Accordingly, Android still ruled the roost at 52.5 percent, while 34.3 percent were iPhone adopters. It's difficult to say whether or not the iPhone 5 had a tangible impact -- while Apple had banner sales in the last several days of September, we don't know to what extent that was offset by people holding off from buying an iPhone 4S.
Overall cellphone sales showed some of that more reassuring give and take. The positions remained the same, but the US was once again a painful market to be in for anyone that isn't Apple or Samsung. Apple crept up to within a stone's throw of toppling LG at 17.5 percent to its rival's 17.7, while Samsung's successful shift to smartphones helped it keep exactly 26 percent of the mobile sphere. We're most curious to see how October shakes out: between a full month of iPhone 5 sales and the Droid RAZR HD, we may learn that the calmness of September was just a momentary illusion.
