Following the leak of Android 4.3 Jelly Bean firmwares for Galaxy S4 and Galaxy Note 2, now it's the turn for one of the most popular Galaxy smartphones. An Android 4.3 test build has leaked for the international model of the Samsung Galaxy S3 bearing model number GT-I9300.

Sammobile has managed to obtain the first ever Android 4.3 test build, which comes with base firmware I9300XXUGMJ9. The leaked firmware has been tested for a few days and is very stable. However, a few bugs are likely as the I9300XXUGMJ9 is a test build. Users are advised to make a backup of all data before installing the firmware.

There are a lot of changes and improvements in the new Android 4.3 firmware over the previous Android 4.1.2. Samsung has reportedly changed the core User Interface (UI) like the one found on the Galaxy S4 as well as Galaxy Note 3. Besides, the Settings app has been completely revamped with a new tabbed interface. Although, Samsung has changed the core UI elements, it is still using the same old original Galaxy S3 launcher and widgets.

Samsung Knox, the new enhanced privacy and security technology first implemented on the Galaxy Note 3, is also not there in the Android 4.3 test build. But, Samsung is expected to add the Knox security feature before the final version is rolled out. It should be noted that this I9300XXUGMJ9 is a test firmware and Samsung might either add or remove features in the upcoming builds of Android 4.3.
