It seems that no software update is complete without a leak before its release date. Androids are no exception. Yesterday, the Android 4.3 (Jelly Bean) software update for the Galaxy S4 was made available online.

Two weeks ago, Sammobile, a Samsung-tracking site, leaked the first Android 4.3 build. Yesterday, Sammobile released the final build of the Android 4.3 update for the Galaxy S4.

"...that means nothing will be included or excluded in future builds of Android 4.3 for the SGS4, except a few bug fixes and improvements here and there," Sammobile said.

Sammobile tested the software for two days and says that there were no major changes as of yet, besides minor improvements.

It has not yet been established if downloading this leaked version of the Android 4.3, which is being called "firmware," is safe for devices, nor has it been determined if the program works perfectly once downloaded.

In the directions for the Android 4.3 download, Sammobile states that "This test firmware is a pre-release firmware and not official from Samsung," and "This firmware will WIPE your device."

Sammobile recommends that downloaders who are willing to take the risk of installing an unofficial update to perform a back-up before downloading. Still, Sammobile insists that they "fully tested this firmware and this firmware works perfectly as any other official firmware."

According to Sammobile sources, the Android 4.3 will be released officially for the Galaxy S4 in the next one to two weeks.
