Comscore, a "global leader in measuring the digital world", has released its July 2011 U.S. Mobile Subscriber Market Share report. The report covers Smartphone and OEM market share activities from April 2011 to July 2011.

With respect to platform marketshares, there wasn't much change at the top with Google and Apple holding steady at the #1 and #2 spot. Microsoft, however, has fallen from a 6.7% market share to a 5.7% market share and is holding steady in the #4 position behind RIM. The report identifies 82.2 million people in the U.S. owned smartphones during the three month period.

With respect to Mobile OEM market activity, Samsung leads the way with 24.5% followed closely by LG with 20.9% and Motorola with 15.6%. We should not that these stats take into account Smartphone and Feature Phone (aka dumb phone) sales those 13 years and older (about 234 million) during the three month period. Apple and RIM, only offering a smartphone, comes in at 4th and 5th respectively with 8.3% and 8.2%.

So, why the decline with Microsoft? Likely most are holding out on investing in the Windows Phone until the new Mango phones hit the market. We still have the wildcard webOS crowd who may seek out Windows Phone as an alternative if webOS doesn't find a life boat.

Microsoft and Windows Phone users are a patient bunch and while a 1% drop isn't good, it will be interesting to see what the next quarter's numbers will look like. Could we see a double digit share of the market?
