Samsung Galaxy S3 Finally Gets The Fixed Android 4.3 Firmware I9300XXUGMK6

Almost a month ago, Samsung released the Android 4.3 I9300XXUGMJ9 firmware update for the Galaxy S3. Unfortunately this release was full of bugs and made the GS3 day to day usage quite frustrating. Finally, after many complaints, Samsung released the updated / fixed Android 4.3 Jelly Bean. The newly released upgrade also lacks the Samsung Knox security feature.

UPDATE: The fix for the issues with Galaxy S III Jellybean 4.3 upgrade has begun rolling out to selected users in the UK, and will continue to do so. Specific upgrade schedules will vary by mobile operators. Please check your phone for the upgrade.

We would like to say again that we are sorry for the inconvenience this has caused, and we assure you that we are doing all we can to get service back to normal.
