Google's Android platform is having little trouble holding onto its No. 1 spot in the U.S. in terms of the number of mobile subscribers. According to comScore's mobile subscriber market share report for the month of November 2011, there were 234 million Americas age 13 and older who used mobile devices for the three-month average period ending in November, many of which are turning to Android.
There were 91.4 million smartphone owners in the U.S. during the three months ending in November 2011, and of those, 46.9 percent were using Android, according to comScore . That's an increase of 3.1 percentage points over the three-month period ended in August 2011, enough to extend its lead over Apple's iOS platform, which accounted for 28.7 percent of all U.S. smartphone subscribers, an increase of 1.4 percentage points.
All other mobile platforms struggled to compete with Android and iOS during the past three months. Research In Motion gave up the most U.S. smartphone market share, dropping 3.1 percentage points to 16.6 percent, though still enough for a commanding third place finish. Behind RIM was Microsoft with a 5.2 percent share (down 0.5 percent) and Symbian at 1.5 percent (down 0.3 percent).
