LG Optimus F7, as long as I know, at this time, comes along with US Cellular carrier and Boost Mobile Carrier. For US Cellular it’s named as LG Optimus F7 US780, for Boost Mobile is called as LG Optimus F7 LG870. It’s designed with touch-bar form factory at 4.7-inch True HD (720 x 1280 pixels) IPS LCD Capacitive touchscreen. The OS is installed with Jelly Bean Android v4.1.2 and powered with dual-core 1.5GHz.
