It means Android grew its lead over iOS very slightly, but everyone else aside from the two most popular smartphone platforms was a loser.
In terms of overall cell phone (both smart- and non-smartphones) manufacturer market share, Samsung ranked as the top OEM with 25.3 percent of U.S. mobile subscribers (unchanged from September), followed by LG with 20 percent share (a slight drop of 0.6 percent) and Motorola with 13.3 percent share (a drop of half a percent). Apple was the sole OEM in the top five that increased its market share, rising 2.2 percent to 12.4 percent. RIM dropped again, from 7.1 to 6.7 percent.
Smartphone use continues to climb. 97.9 million people in the U.S. used smartphones during the three months ending in December (up from 91.4 million people in the previous comScore ranking).
In terms of mobile phone use, comScore's survey showed that 74.3 percent of U.S. mobile subscribers text messaged in December, up 3.2 percentage points. 47.6 percent of mobile subscribers downloaded applications, up 5.1 percent. 47.5 percent of subscribers used Web browsers on their devices, up 4.6 percent.
31.4 percent gamed on their devices, up 2.6 percent, and 23.8 percent listened to music on their mobile phones, up 2.9 percent.
In a positive note for those waiting for Facebook to go public (as opposed to its S-1 filing on Wednesday), 35.3 percent of mobile subscribers accessing social networking sites or blogs during the period, up 3.8 percent.
It was a pretty "positive" comScore result, with the losers being LG, Motorola, Microsoft, RIM, and Symbian, and with Android and Apple continuing to rise.
A recent Nielsen report showed that iPhone sales skyrocketed in Q4 2011, meaning that although market share continued to go the way of Android, that might change. Much of that recent sales rise was driven by the iPhone 4S; it remains to be seen if the recent Android introductions (Galaxy Nexus, RAZR, RAZR MAXX and the upcoming Droid 4) will reverse that trend.
