Selling 10 million units of smartphones — a feat that LG reached back in December with its Optimus L-series lineup — is nothing to sneeze at. Now, the company has even more impressive news to share.

According to the Nexus 4 maker, an additional 5 million units of the series have been scooped up by customers in the past two months or so. In total, LG’s popular budget range has sold to the tune of 15 million units, with one L-series phone apparently sold every second.

Coupled with the reported brisk sales of the Optimus G and its Nexus twin, no wonder LG is moving up the Android manufacturer ladder. The Korean is showing no sign of slowing down, as it’s aiming to sell 45 million smartphones in 2013.

Helping the company get there is the successor to the L-series models. The new L-series II family — consists of the Optimus L3 II, L5 II, and L7 II — was announced earlier this week by LG, which as expected don’t offer anything too exciting in the specs department. But hey, as long as they’re priced right, there’s no reason why the new models won’t fly off the shelves.
