You are aware that this is the Nordics part of the forum, we have very little to no knowledge about Korean updates. My best tip would be to check in with the Korean Members forum or to keep track of updates from Sammobile or another FW-dedicated site... In general, there is no announced schedule for updates, they are rolled out when they are. It depends on things like carriers etc. And updates are rolled out in batches, so not everyone get it the same date, or week.
