The LG K7 is the middle smartphone of the new K series, consisting of the K4, K7 and the K10. The K series does a great job of bringing new design into an otherwise uninspiring market where many of the devices are starting to look the same. It will be interesting to see how much design plays in influence on what OEMs make in the future.
The K7 smartphone comes in two unique models: the 3G variant of the LTE version. You need to make sure you are looking at the specs for the right device, as they can change between the two. Most notably, the internal memory will change, the camera megapixels, and the CPU will change.
