After a half-year fall from the top-five grace, LG is back and in the No. 3 slot with 10.3 million units sold, an increase from last year of more than 110 percent and a record for the company. Driving its success were its L-series and Nexis 4 phones, both of which are of the 3G variety. Also high on LG's hit list was its Optimus G LTE phones. The Korean electronics giant is pinning its hopes for continued success on its new F-series mid-range phones and entry-level L models.
