Hello, what's this? While many of us were out enjoying the spring weather, @evleaks was busy posting photos of an unknown LG smartphone that, if real, represents a notable shift in the Korean company's design language. The device shares the Nexus 4's slightly curvy outline and lack of front-facing hardware buttons, but appears to have a taller screen, a new speaker grille and a different sensor layout. It's not very likely to be part of the Nexus program with that conspicuous LG logo at the front, but there are few other clues as to where it would fit in LG's phone family -- is it an Optimus G sequel, an Optimus LTE2 follow-up, or something entirely fresh? We may well see more of this mystery hardware in the near future, though, and there's already a close-up of the top bezel to be found after the break.
