If you’ve got the AT&T Samsung Galaxy S6 (SM-G920A) and S6 Edge (SM-G925A), you folks may have gotten an update to Android 5.1.1 Lollipop early this morning. Yes! AT&T has finally started rolling the Android 5.1.1 Lollipop.  This update will bump the Galaxy S6 to  baseband version G920AUCU3BOI2, and it weighs in at staggering 660.90 MB (or a bit less, according to the screenshot above).  Meanwhile,  the Galaxy S6 edge will move its baseband version to G925AUCU3BOI2.

The push might be in connection to the Samsung Pay’s launch in the United States.  Though the initial changelog details have not yet been confirmed, as AT&T's Support pages isn't updated yet. But on Samsung US support pages it says that it has  Network Enhancements (CIQ) included in it.

But if we just base on the update's enourmous file size and looking back to Android 5.1.1 update running on other carrier's Galaxy S6. It should have some few changes to notice beforehand. You may then notice the new rounded Apps icons and some new features like the Samsung Pay, Live streaming in the camera app and UHQ audio, wallpaper motion effect, rotate button in calculator, might also have some few apps from AT&T itself and etc.

Fortunately, the update is only available via Over-The-Air (OTA) over a Wi-Fi connection and couldn't be seen via Smart Switch for PC/MAC. The release might run into several days and not everyone may get the update at the same time.  So if you haven’t yet gotten your update, you can check for it manually by heading into Settings > About device > Software update. If you'll received a message that says something like "Software Update Interrupted. No update is available for your device at this time. Please try again in 24 hours", Don't panic,  it only means that the server is busy, so you should keep on checking until you'll get an open slot and you may then download the update.
