The LG G4 was last year's flagship for LG, but it's still a smartphone that will compete with today's high-end devices. The LG G4 sports a 5.5-inch QHD display, powered by Qualcomm's Snapdragon 808 hexa-core processor along with 3GB of RAM. There is 32GB of storage included here, along with a micro SD card slot that can support up to an additional 256GB of storage. So there's plenty of storage available for the user. All of this is powered by a 3000mAh battery that is removable - something you don't see with many smartphones today. The back is removable here, so you can swap out the plastic back for one of the nice looking leather ones. This particular listing offers the LG G4 in either black or the brown leather back.
Now this is the H811 model, which was made for T-Mobile in the US. It does have the right bands to work with any GSM carrier, as well as being unlocked. Meaning you could take it over to AT&T, MetroPCS, or any other MVNO that runs on either of their networks. Unfortunately, those on Sprint and Verizon or even US Cellular are out of luck, due to them being CDMA carriers, and not being compatible.
