LG have used Mobile World Congress this year to show off their entire range of smartphones, something the South Korean company calls their "four-tier strategy". LG should easily pull this off, as they have a large variety of smartphones under their belt now.

This includes the Optimus G Series, Vu: Series, F Series and LII (L2) series. We've already seen what LG are capable of with their high-end smartphones, the Optimus G series. The Optimus Vu hasn't exactly set sales records, nor has it got consumers tripping over themselves buying it, but they're continuing to put effort into it adding pen input and multi-window apps which are part of their QSlide software.

The two latest additions to LG's smartphone lineup are the F Series and II Series. Both of these enter the middle- and low-end markets, respectively. The F Series will see the F5 and F7 smartphones, which have decent specs and should be LTE-capable. The LII Series concentrates on design instead of the best specs, where it allows LG to mess around with the design without hurting their other, more expensive devices.
