After a couple of leaks last week all but completely unveiled the Optimus F7 and F5 to the general public, LG's made the devices official today at MWC 2013. The two handsets are part of the company's mid-range line, devised as a bridge for users crossing over from aging 3G networks to LTE. But that's not all the 4.7-inch F7 and 4.3-inch F5 have in common. Both run Android Jelly Bean 4.1.2 (skinned) and pack a dual-core setup, 8GB of internal storage, 1.3-megapixel front facing camera and LG's suite of custom software. Of course, there are bound to be significant differences between the two, so follow along as we dive into our initial impressions.
