Poland and its S800-based Galaxy Note 3 unites were the first to taste the Android 4.4 KitKat with the latest TouchWiz upgrade. It seems the update has had no major issues as now Samsung is pushing it to other regions as well.
The Exynos-powered Galaxy Notes 3 in Russia have been recently updated with KitKat, while today both Exynos and S800 Note 3 units in South Korea, India, and the Baltic region (Estonia, Latvia, Lithuania) are joining on the KitKat fun too.
We guess the update process will now be hitting full steam and may more countries will be joining those in a few days. Reportedly the OTA update weighs at about 360MB, so you might want to make sure you download it over Wi-Fi when the time comes.
