Sprint has begun rolling out its Android 4.3 update for the Samsung Galaxy S4, just a day after the update was made available to users on Verizon.

The update weighs in at a whopping 537MB, and it’ll be available to download over-the-air. In addition to Android 4.3 and all the improvements that come with it, this update adds Galaxy Gear support, KNOX functionality, and more.

Android 4.3 first began making its way to the international Galaxy S4 two weeks ago. Samsung doesn’t give us a change log with its software updates, but here’s what came with that one:

– OpenGL 3.0 Support
– TRIM Support (Makes the device much faster)
– ANT+ Support
– Samsung KNOX Implementation (KNOX bootloader and dedicated application)
– Samsung Wallet comes pre-loaded
– Improved RAM management
– Improved Display color reproduction (Display looks much sharper than before)
– Improved TouchWiz Launcher (Much less launcher redraws and less lag)
– New Samsung Keyboard
– New Samsung Browser (Full screen by default, new tab interface and more)
– New Reading Mode (Optimizes display for reading, used by only a few specific applications)
– New Camera firmware
– Minor UI tweaks (Contacts app, Flashlight Widget, dialog boxes etc)

The Sprint update should be largely identical, so users should be able to enjoy all of the changes and improvements listed above. If you haven’t received a notification for the update yet, tap the “update” button within the software update menu.
