Galaxy S3 I9300 users in France finally get some relief, thanks to the release of XXDLJ2 ROM based Android 4.1.1 firmware update over Samsung KIES. Another pleasant surprise for S3 users is that the firmware reportedly supports most of the countries without issues.

The full list of countries or regions supported by the firmware includes Austria, Belgium, France, Germany, Hungary, Italy, Spain and the United Kingdom. Samsung has been releasing software updates in phases, although the Galaxy S3 gets the maximum number of custom ROMs and official updates as it is Samsung's flagship smartphone. However, there is still no word on the release of official Android 4.1.2 Jelly Bean update for Samsung devices.
