Samsung may be facing technical difficulties in updating the Galaxy S3 in Europe, but everything seems to go to plan when it comes to the American AT&T version of the Galaxy S4.

The AT&T Galaxy S4 Android 4.3 update has kicked off in earnest today, with AT&T users reporting on XDA-developers and other channels the presence of an over-the-air update package that weighs in at 719MB. The update brings support for the Galaxy Gear smartwatch, Samsung’s Knox secure work environment, and slew of under the hood improvements, such as support for OpenGL 3.0, support for the TRIM command (should speed up flash storage), better RAM management, and enhancements to Samsung’s proprietary apps. Overall, your AT&T Galaxy S4 should receive a slight speed boost, thanks to the tweaks applied in this update.

The Android 4.3 update brings firmware to build number JSS15J.1337UCUEMJ9, and rolls out as an OTA now. Check out the About Device section on your Galaxy S4, though patience is the name of the game with OTA releases.

With the Android 4.3 updates for Sprint, Verizon, and US Cellular behind us, and now AT&T joining the fun, T-Mobile is the only big carrier left to roll the update to the Galaxy S4. According to a leaked roadmap that proved accurate so far, we can expect T-Mo’s update around November 18.
