If you own a Samsung Galaxy S III on AT&T’s network, be on the lookout for an OTA update if you haven’t already received it. A lot of users are reporting it’s a small update — only 82MB — but it comes packing with a few user interface changes, as well as a handful of bug fixes.

Some of the user interface tweaks include the addition of a screen brightness adjuster in notifications, a new “VPN Client” app, keyboard improvements, added effects to the default camera app, and auto-scaling of widgets (not to the extent of Jelly Bean, though). AT&T doesn’t say what all has been improved and fixed, so you’ll have to do some exploring to find out what all changed.

The Galaxy S III is Samsung‘s flagship smartphone and was released over three-and-a-half months ago. It’s already sold over 20 million units and is one of the best smartphones on the market right now. It’s certainly nice that Samsung and AT&T are keeping it fresh with updates, and we’re pretty excited for Jelly Bean to come aboard next month.

If you’re having problems with the update (a handful of users are, apparently), you can head over to the dedicated thread on XDA Developers. If you’re safely up and running with the new update, let us know how it is in the comments!
