After officially announcing its new K-series of smartphones at CES, and launching the K10 smartphone, the company has now teased a third member of the lineup. In an official LG K10 and K7 product video, at the end, we can clearly see the unannounced LG K4 smartphone.

Since it looks smaller than the K10 and K7, which have 5.3-inch and 5-inch displays, we can assume the K4 should be around 4.7-inches. It will be an entry-level smartphone sold at an affordable price tag. As for the availability, pricing and specifications, you'll have to wait for new rumours to come out.
