LG has been always late in bringing software updates to its Android smartphone (even flagships), but it looks like things have changed a bit. LG Korea has officially announced that they will be rolling out the latest Android OS update, Android 4.4 KitKat, for LG G2 in Korea later this month. The update is reported to get rolled out before the end of this month, the dates aren't yet revealed.
The update has been only announced for South Korean LG G2's, hope LG reveals the 4.4 update plans for international G2 soon. LG G2 was launched with Android 4.2.2 Jelly Bean and is skipping Android 4.3, and directly jumping to Android 4.4 KitKat.
