There are some users who are seeing that their Galaxy S3 and Samsung Galaxy S4 receiving the Android 4.3 Jelly Bean proper and infection free update in Europe. Hard to the fact that the update was first rolled-out but was shortly found to be infested by a lot of bugs and was pulled ever since. Not after AT&T resumed seeding the fixed version of the Android 4.3 Jelly Bean update and now the update has started making its way to other regions.
Users that have installed the Android 4.3 Jelly Bean update with the bugs should shortly receive a small patch update through Samsung Kies and the Samsung Galaxy S4 should receive Android 4.4 KitKat soon as well so this is not the last one.
