Future plans for rollout in other markets not yet available
LG has announced that it will begin rolling out an update to Android 4.4 KitKat for Korean variants of the G2. Speaking specifically of the model for its own domestic market, LG says that KitKat will be hitting its flagship by the end of the month, and considering that we're half way through December we have just two more weeks to wait before at least some G2s start seeing the software.
Unfortunately no specifics are given on what changes LG plans to bundle along with the move to KitKat, nor does it offer any timeframe for G2s in Western markets. Considering the carrier involvement here in the states that's not hard to imagine, but knowing that LG has the software ready for at least one variant has us hopeful that it won't be too long before we have more information on a more advanced rollout.
