Q4 smartphone numbers are in: Android rockin’ 53.4% of US market share

Thanks to comScore’s latest report, which ranks platform market share as well as the top five U.S hardware OEMs, the numbers are in for the final quarter of 2012. Nearly 126 million people in the U.S. owned smartphones between September 1st and December 31st, representing a 5% growth from Q3 2012.

On the platform front, Android is still dominating with a massive 53.4%, growing slightly from last quarter by 0.9%. Apple comes in at second place with 36.6%, growing 2% over the past 3 months. Both BlackBerry and Windows Phone continued to decline between Q3 and Q4 falling a few percentage points each.

Besides sheer market share, comScore also monitors mobile phone manufacturers. With almost no change from last quarter, Apple remains on top, producing 36.3% of all mobile phones. Samsung out grew Apple last quarter by gaining a few percentage points in Q4, coming in at 21%, HTC continues to decline, dropping nearly 2 percentage points last quarter. Motorola dropped less than 1% and LG gained less than 1%. Maybe LG would have risen a bit more had the Nexus 4 been easier to find?
