With the release of Android 4.4 KitKat through Google Nexus 5, several Android manufacturers being rolling out the update to their own devices.

Samsung is among those who have yet to complete the release among its devices. According to the company, it will be rolling out the Android 4.4 KitKat update to Samsung Galaxy Note 3 and Samsung Galaxy S4 throughout the first quarter 2014. For users unsure when they would receive the update, developers at XDA leaked the builds for the new OS.

Samsung has been working on getting the Android 4.4 KitKat device to its international models and U.S. devices for the past couple of weeks. Specifically, the company has been testing and certifying builds for Samsung Galaxy Note 3 and Samsung Galaxy S4. But as the roll out may not take a couple of weeks for some regions, some users grow impatient on when they can try out the OS.

For third-party providers like XDA developers, users have the option to test the builds of the operating system. Designgears, a member at XDA Developers forum, has provided the leaked builds for Android 4.4 KitKat under AT&T.

The leaked builds cater to Samsung Galaxy Note 3 and Samsung Galaxy S4 devices under American carrier AT&T. For those who cannot wait for the official release of the update, they can download the builds and flash their devices.

It is important for users to understand that the leaked builds are test builds. This means providers of the update cannot be held responsible for what happens to the devices after flashing. Users can download and update at their own risk.

The KitKat builds provided at XDA are not official and there might be some features on the over-the-air update which may not be present on the leaked builds. Users should be prepared for reboot issue with their Samsung Galaxy S4 build. The reboot issue surfaces when working with video codecs. As for people who do not mind minor issues, they can choose to use the builds as provided. It is best to double check flashing instructions to avoid problems.
