LG Electronics has pushed Apple into third place in the North American mobile phone market.
LG rose to second place with a 13 percent share in December, overtaking Apple, which had 12 percent, according to Hong Kong market researcher Counterpoint Research.
LG was in second place in North America until the third quarter of 2011, when it ceded the position to Apple after the release of the iPhone 4S.
But sales of Apple's new smartphone, the iPhone 5, have been poorer than expected, while LG is doing brisk business with the Optimus G and Nexus 4.
With Apple performing poorly, Motorola and Taiwan's HTC also increased their market share, to 9 percent and 8 percent. Samsung Electronics held the top spot with 33 percent.
