There is no official update schedule, and the first reports confirm that KitKat has started seeding to the LTE-Advanced (LTE-A) Snapdragon 800-based version of the Galaxy S4 in Korea. The new firmware brings the Android version of the S4 up to 4.4.2 and is allegedly available for download either over the air (OTA) or via Samsung’s Kies software.
What does Android 4.4 KitKat bring to the Galaxy S4? Initial reports mention an improvement in overall speed of operation thanks to better RAM management, and TouchWiz is also said to have been bumped to its latest version, coming with a slight facelift.
If you are wondering what’s happening with the international rollout of the KitKat update for the Galaxy S4, right now Samsung has already missed its January deadline, but chances are that it should start arriving very soon, given the fact that Korea is getting it and that a test ROM has already leaked out.
And Samsung better hurry up - the Galaxy S5 is expected to get officially unveiled in just around three weeks on February 24th at the Mobile World Congress in Barcelona. Having KitKat on the Galaxy S4 by that time, would be great, don’t you think?
