Android 4.3 leaks for a bunch of AT&T Samsung devices: Galaxy S3, Note II, S4 and S4 Active

DesignGears, a well-known Android developer, has recently leaked Android 4.3 test firmwares for a bunch of AT&T Samsung devices. That include: AT&T Galaxy S III (SGH-I747), AT&T Galaxy Note II (SGH-I317), AT&T Galaxy S4 (SGH-I337) and AT&T Galaxy S4 Active (SGH-I537). Yesterday, guys over at geek.com got hold of a leaked Best Buy document which revealed that AT&T will officially update the Galaxy S4 in last week of October, Galaxy S III and Galaxy Note II in November and Galaxy S4 Active in December.

CHANGES AND IMPROVEMENTS IN ANDROID 4.3 UPDATE
- Galaxy Gear 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 colour 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 (Optimises display for reading, used by only a few specific applications)
- New Camera firmware
- Minor UI tweaks (Contacts app, Flashlight Widget, dialog boxes etc)

Keep in mind that these are pre-release firmwares, they are bound to have bugs and stability issues and are no where near final builds. But, if you really can’t wait till the official roll out and want to taste that Android 4.3 goodness then head over to the firmware thread located over at XDA-Developers for your respective device, where you will find the download link, instructions and more.
