A little digging around the FCC's website has revealed the existence of another unannounced Samsung Smartphone. Carrying the model number SM-G7102, the device reportedly features a large 5.2-inch display and is powered by a 2.3 GHz quad-core processor (which can't be anything else but Qualcomm's Snapdragon 800 chipset in action) and come with Android 4.3 out-of-the-box. Its display's pixel density isn't too exciting, just 288ppi. We're looking at an HD (1280 x 720) display here, which would have been fine on a high-end 5.2-inch phone if we were still in 2012.
Also, the SM-G7102 will reportedly be a dual-SIM enabled device, which would make it one of Samsung's most powerful dual-SIM phones on offer.
