The large-screen smartphone market is now one of the most fiercely competitive in the wireless industry. But even though nearly every phone maker has produced a competitor to the Samsung Galaxy Note, only a handful of products have actually been worth considering. LG's Optimus G Pro, a 5.5-inch flagship introduced last year, was one such exception. A year later, its 5.9-inch successor picks up where the first Pro left off, adding enough extra firepower to take on the Galaxy Note 3 spec for spec. The LG G Pro 2 may very well have what it takes to stand up against its big-screen rival, but it'll have to overcome a few minor obstacles in order to succeed.
