At long last U.S. Cellular pushes out the rather hefty, much-anticipated Android 4.4.2 over-the-air (OTA) update to all Samsung Galaxy S3 handsets located in the United States. The upgrade brings the latest build of KitKat to the handset, complete with a multitude of additional bug fixes and speed optimizations.

Android 4.4.2 is a considerable upgrade from 4.3, packing a completely redesigned user interface, SMS message integration in the standard Hangouts application, Google Now on the home screen, Wi-Fi printing capabilities for HP ePrinters and Google Print customers, autocomplete for the traditional telephone dialer, Emoji integration, built-in word processing software and lots more.

The full changelog for the 300MB update can be seen below:

• Android 4.4.2 OS upgrade.
• Improved system performance.
• Transparent notification bar.
• Improved RAM management.

If you own a Samsung Galaxy S3 on U.S. Cellular and haven’t yet received the OTA update, you can head into “Settings,” then “About Device,” and select “Check for Updates” to manually scan for the upgrade.
