I just happened to be browsing around and of course saw all the screenshots of Android 4.3 on an S4. Anyhow, I do not own this device, therefore I cannot test or confirm whether it works or not, and this also applies that if you test, it is at your own risk. Anyhow here is the link for the download that is available in both Deodexed and Odexed. Enjoy!
