comScore has released its US smartphone subscriber study for the three month period ending July. Reflecting similar observations by Millenial Media, iOS continues its ascendancy in the US market. comScore computes its marketshare figures based on active subscribers, which is generally seen as a more reliable representation of market trends than web usage traffic, which is what Millenial uses.
comScore reports that iOS was the only platform to show positive growth, rising 1.2 points from 39.2% in April to 40.4% in June. In comparison, Android fell 0.2 percentage points with even larger decreases experienced by BlackBerry which dropped from 5.1% to 4.3%. Windows Phone’s share remained constant at 3.0%.
