Yes, Android 4.3 firmware has been leaked for Samsung Galaxy S4. Even though it is a leaked firmware, it is very stable and much faster than Android 4.2.2. This version comes with many new improvements and enhancements. Now Samsung Wallet is a default app and Samsung Knox, which is an application to protect your phone, seems to be working perfectly without any problems.

Keyboard is improved for a better typing experience and there is a new Reading Mode which optimizes the screen to make everything look sharper. And another big improvement is the color reproduction. This means that colors are improved and there’s less black clipping.
