The leak stems from a Samsung insider with access to an early build of Android 4.3 (JWR66N) as the company adapts it to run on the phone’s hardware. This insider, who provided screenshots as proof, believes the phone will actually be updated with the latest “Jelly Bean” installment this July. That said, we’ll likely see the HTC One Google Play Edition get the same first-class Android 4.3 love next month along with the Nexus 4, Nexus 7 and Nexus 10.
Install Android 4.3 on your Galaxy S4
A recently leaked Samsung firmware based on Android 4.3 (JWR66N for those keeping track) has been found to work pretty darn well on the original TouchWiz-laden Snapdragon-powered Galaxy S4. However it was not rootable until today, and therefore somewhat less viable of an option for those who can’t live without their root applications. Cue XDA Elite Recognized Developer Chainfire and his modified version of SuperSU, which is specially adapted for use with 4.3.
For this root, SuperSU is running in daemon mode (new feature), and launched during boot.
The daemon handles all su requests, and while this should mostly work just fine, some apps may expect their su session to be running on the same branch on the process tree as the app that launched the session.
Whether these changes are due to Samsung or just Android 4.3 in general remains to be seen. But needless to say, once we see a few more 4.3-based firmwares, we will have an answer. There are also some other differences that will you will want to be aware of, especially those of you using a CWM-based recovery, so I highly recommend checking out that post in full. For how to root android 4.3 follow on.. If you’re currently running the 4.3 leak on your S4, this is probably something you’ve been looking forward to for a few days now. The flashable zip file itself can be downloaded from the Google+ post, and the current SuperSU thread should be used for any related issues.
