LG's latest K-series of smartphones officially has only two members, the LG K10 and K7, but we have already seen the unannounced K4. Besides the LG K4, at its official Facebook page, the company has confirmed other smartphones from the same affordable lineup.

The lineup consists out of five smartphones, including LG K4, K5, K7, K8 and K10 devices. The K4, K5 and K8 have yet to be announced, but since the company has confirmed them several times, one through a video and now on Facebook, it is probably only a matter of time before they go official.
