Team Kang is currently launching nightly Android 4.4 AOKP builds on the Samsung Galaxy S4, giving owners of the device the opportunity to experience the KitKat OS ahead of the official release. As you might expect, nightly builds are still under development and they may contain bugs, but on the bright side, new AOKP nighlies are being launched in a timely manner, so a bug today might be dealt with tomorrow.

This is a guide for installing the latest Android 4.4 AOKP custom ROM on the US Cellular Samsung Galaxy S4. One thing that you need to keep in mind, is that AOKP is based on KitKat as well as CM 11. It features vanilla Android user interface, so TouchWiz will no longer be an option once you apply this ROM.
