Coming just a day after LG announced their Optimus L Series II line of smartphones, sales of the currently available Optimus L Series devices have reached a new milestone. In short, LG has said Optimus L Series sales have topped 15 million. This handset originally launched during Mobile World Congress in 2012 and according to LG, has been selling at the rate of one device per second over the previous two months.

Looking back, the Optimus L Series reached the 10 million mark back in December of 2012. Given those details, it now makes perfect sense as to why LG announced the Optimus L Series II line. Why mess with a good thing? Of course, while LG has already announced the Series II line of handsets, they are still planning to make an official unveiling during Mobile World Congress 2013. LG has said the Optimus L Series II devices will “carry on the legacy of its predecessor, offering a user experience unique to LG smartphones.”

Coming from the previous announcement, we know the Series II devices will include the Optimus L3 II, L5 II and the L7 II. We have yet to see a full set of specs for the complete line, however LG did offer enough to give an idea. The L7 II will be the top of the line and include a 4.3-inch WVGA IPS display, dual-core 1GHz Qualcomm MSM8225 processor, 768MB of RAM, 4GB of internal storage, a microSD card slot, 2460 mAh battery, VGA quality front-facing camera and an 8 megapixel rear-facing camera.

Shifting over to the L5 II and the L3 II and we know that these will have a 4.0-inch WVGA and a 3.2-inch QVGA IPS display respectively. Otherwise, the only other bits that LG has shared in terms of these two include the battery sizes, which will be 1700 mAh and 1540 mAh. Regardless though, MWC is quickly approaching and we know more information will be available at that time.
