The Samsung Galaxy S3 Android 4.1 Jelly Bean update is having its second wave rolling out this week.

News has emerged that Samsung has released the new upgrade in Sweden over KIES with a brand new build “XXDLI,” and the software should be further rolled out across more countries in the near future.

Along with the new Jelly Bean update come new features such as Google Now, a smoother UI, as well as offline voice typing support, expandable notifications and more user-friendly settings.

However, the U.S. version of the Galaxy S3 will be one of the last versions to receive the JellyBean software, and will be a source of frustration for customers there.

The Jelly Bean update for the S3 was finally confirmed for the U.S. recently. The handset will receive it on all five of major U.S. carriers including AT&T, U.S. Cellular, Sprint, Verizon, and T-Mobile.

For Sprint users a leak has already emerged which shows up as a ROM at XDA's developer's forum, where it can be installed on the Samsung Galaxy S3. TouchWiz skin is included in the leaked build, which also comes with Project Butter and Google Now.

Meanwhile, a new Samsung Galaxy S3 with Android 4.1 JellyBean already pre-installed will be launched in Japan later this year, according to new reports. The variant of the device will come with a 1.6GHz Exynos chip that allows this S3 to function at faster speeds than the international and U.S. versions of the best selling handset.

According to rumors the device will be released in both black and grey and will probably also be released in other color variants soon after release for customers to have more choice.
