Samsung's Galaxy Note 3 may already be running the latest version of Android in some places. Here in the US, however, most carriers still haven't updated the faux leather-covered device to KitKat. But, starting today, at least a good number of Note 3 owners will be getting a taste of it, with AT&T announcing that its version of Android 4.4 is now rolling out to the 5.7-inch handset. You can expect to experience quite a few new things as part of this, such as a revamped user interface, improved GPS and the option to choose a default messaging app. The update is said to be available now -- all you need to do is tap your way to that Software Update menu, download the goods and voilà.
