Apple became the biggest vendor of mobile phones in the US for the first time, selling an estimated 17.7 million units in the fourth quarter, for a 34 percent market share. This compares to 12.8 million units and a 25 percent share in Q4 2011. Samsung sold 16.8 million phones for a 32.3 percent share in Q4 2012 compared to 13.5 million phones and a 26.9 percent share in Q4 2011. LG sold 4.7 million units for a 9 percent share in Q4 2012, versus 6.9 million and 13.7 percent in Q4 2011.
Samsung was the top phone vendor for all of 2012, taking a 53 percent share, ahead of Apple's 43.7 percent and LG's 20.5 percent. In 2012, LG lost market share as it struggled to compete with its bigger rivals in the high-growth smartphone category, but it will fight back this year with models such as the Optimus G LTE Android phone, said Linda Sui, analyst at Strategy Analytics.
