The official Android 4.3 update for Galaxy S4 is scheduled Oct/Nov release, and before the update goes live you can have a look at what all changes you will notice after the original update.

According to the Sammobile's post, the new update is very stable and the performance has received a significant boost, much faster and lag free than Android 4.2.2. The update will bring Samsung's own Knox security service and Samsung Wallet. Sammobile reported that, the Knox service works flawlessly on the smartphone, but there are problems with Wallet.
