Yesterday LG teased a 48 second mysterious video on YouTube that showed off various angles of new devices on their G, L, V and F series. LG only noted that we’ll “see the difference” at Mobile World Congress. However, why wait for MWC when the some of the details will unfold itself on Twitter. According to reputable device leaker EVLeaks, LG will announce the LG Optimus F7 and the Optimus F5. The pictures are above – the Optimus F7 is on the left and Optimus F5 is on the right. No details of specs, but both will run Android and looks incredibly similar to the Optimus G in design.
