A new and official Android 4.3 Jelly Bean update has been rolled out to Samsung Galaxy S3.

As posted on International Business Times, a fresh stock firmware based on Android 4.3 Jelly Bean update is now available for the global version of the Samsung Galaxy S3. The latest Android 4.3 Jelly Bean update has build number I9300XXUML2. The post reads, "This update comes after Samsung resumed Android 4.3 upgrade service, which was suspended temporarily following users' complaint over major bug issues."

Users of Samsung Galaxy S3 who are interested to install the official Android 4.3 Jelly Bean update can do so using either the Over-The-Air notification or the Samsung KIES desktop tool.

However, for those who cannot wait for the OTA update to arrive on their region, Galaxy S3 owners can opt for the manual installation process.
