The LG G Flex 2 is a pretty good phone, even compared to LG's own flagship G4, and it's a great option if you're tired of all the ever-bigger screens that seem to be the current rage. It's also got a pretty decent price: US Cellular sells it for $50, AT&T sells it for $100, and Sprint is selling it for $200 at the moment, with off-contract prices ranging from reasonable at around $500 to ludicrous at over $700 (thanks, AT&T). If you want a good deal without the carrier ball and chain, Expansys is currently selling the phone for just $329.99.
That's about $170 off of the cheapest outright carrier price, and a good $30-100 off of the international models sold on Amazon (with no warranty). The phone on Expansys is a brand new 32GB version, and this GSM-LTE model should work on AT&T, T-Mobile, and other GSM-based networks in the US and elsewhere. (It lacks the 1700MHz band, so T-Mo reception may be spotty depending on your location.)
Other specs include a 5.5-inch 1080p OLED curved screen, 2GB of RAM, a MicroSD card slot, a 13MP rear camera, and a respectable 3000mAh battery. The processor is a Snapdragon 810 rated at 2.0GHz, but in his review David Ruddock concluded that it was severely underclocked to prevent overheating. Expansys is offering free standard shipping to the US. The international version is running Android 5.0 according to the spec sheet, but it shouldn't be too long before the 5.1.1 update is sent out.
