We're starting to see a distinct shift in US smartphone market share that leaves Android having to share the spotlight. ComScore's results for this past June have Google hitting a new high of 51.6 percent share, which still gives it something to crow about -- that's both a small increase over a month earlier and a return to the 51 percent mark. However, Android is still competing with an iOS platform that's been growing at a healthy rate, reaching 32.4 percent of the American space. The fuel for both sides comes from an all too familiar decline in BlackBerry, Symbian and Windows share. Samsung is still in the top spot as far as manufacturers, although it's shrinking where Apple and HTC are on the way up. We'll be looking to see how much the Galaxy S III affects the numbers during the summer, but less patient observers can get the manufacturer results after the break and the full scoop on current market share at the source.
