Since its release date, Samsung Galaxy S3 owners have eagerly awaited the Android 4.1 Jelly Bean update. Samsung announced that the next-generation software will roll out in September, but did not specify a specific date.

However, Galaxy S3 users with a knack for tinkering with their devices may be in luck. A new build of the test firmware for Android 4.1.1 Jelly Bean has reportedly leaked out, according to Sam Mobile. The latest version, known as I9300XXDLI5, is said to be the "most stable leak" to date. The Samsung-themed website said that nearly all of the issues from previous builds have been fixed in this updated version.

"This build is very much near perfect so we believe that Samsung will actually start rolling out the Official Jelly Bean update for the Samsung Galaxy SIII very soon," writes Sam Mobile. When the release date for Android 4.1 Jelly Bean actually hits, users will be able to install the software via Kies or an over-the-air (OTA) update.

Sam Mobile says that they are receiving leaks for Android 4.1 Jelly Bean every day, which indicates that the update is likely to launch in the next week.

Below is a list of noticeable changes found in the new test firmware:

- Maps compass is fixed.

- Maps arrow for direction is fixed.

- User interface is smoother and faster.

- Smart Stay is improved.

-  Very stable.

-  No FCs

The website warns that this is a pre-release of Jelly Bean and it is not the official version, so users should expect some minor bugs.

This is one of many leaked versions of the Jelly Bean software for the Galaxy S3 that has surfaced in the past couple of months.  The same website obtained Android Jelly Bean firmware near the end of August, which offered users an opportunity to test the new software update ROM. This version of the software was called I9300XXDLG4, and dates back to July 31. Some users experienced issues with this build, such as the formatting issues with the internal SD card which could prevent some apps from being installed. However, these issues are said to be resolved with the newly leaked edition.

As Galaxy S3 Release Date Nears, Jelly Bean Expands

Last week it was reported that Android 4.1 Jelly Bean has expanded to 1.2 percent of the overall Android market share, according to ZDNet. Android is known for rolling out its updates slowly and steadily, as Android 2.3 Gingerbread still remains the most widely used operating system.

However, the latest software upgrade seems to be releasing to Android devices at a surprisingly timely rate.

According to data collected by Google, 1.2 percent of Android devices accessing the Google Play store within a 14-day period which finished on Sept. 4 were running on Jelly Bean.

It was also reported that Android 4.0 Ice Cream Sandwich is present on 21 percent of Android devices, becoming the second most-deployed version of Android. This is based on the same data cited above.

Android 4.1 Jelly Bean is referred to as "fast, fluid, and smooth" in its official description, and boasts improved performance across the Android system. Devices already running on the updated OS include the Nexus 7 tablet, the Motorola Xoom, the Galaxy Nexus and the Nexus S.
