LG has started rolling out Android 4.4 KitKat firmware for various devices available only in South Korea. The first one to get it is the South Korean model of the LG G Pad 8.3 slate. The update is available both via OTA service and LG's Mobile Support Tool.
LG Vu 3 has been brought onto the KitKat bandwagon too. Its KitKat firmware is available for all three carrier-bound versions in South Korean, but you must get it via the local LG support website.
LG has already launched KitKat updates for the LG G2 and G Flex worldwide. LG Optimus G Pro is also getting Android 4.4, but it is available only in South Korea for now. It seems LG is putting quite the efforts to bring its devices on the latest Android version. Hopefully more internationally available smartphones will get the same treatment.
