LG released an updated version of the K4 smartphone in 2017.

The LG K4 models include either Single-SIM or Dual-SIM card capabilities. In Dual-SIM versions, one SIM card can be in use while the other card is in standby. It includes 8 GB of internal storage and 1 GB of RAM. The K4 includes a 1940 mAh removable battery, meaning that the battery is not attached to the inside of the phone using any kind of permanent adhesives.
