Almost all major carriers in the U.S. have already rolled out the Android 6.0.1 Marshmallow update for Samsung Galaxy S6 and Galaxy S6 Edge released in April 2015. However, firmware for AT&T versions of the aforesaid handsets got delayed for a long time.

Now, the latest news is that AT&T has finally started pushing the Android 6.0.1 update to its Samsung Galaxy S6 and S6 Edge units. The downloadable file is reportedly 1.45 GB in size. Upon downloading and installing the software package, the AT&T handsets should show the following build number: MMB29K.G920AUCU3CPD6.

The Android 6.0.1 Marshmallow OTA update is being rolled out in phases. Hence, AT&T’s Samsung Galaxy S6 and Galaxy S6 Edge owners may have to wait a couple of days before every unit gets the firmware notification. The other way is to check the Settings menu of the handset for notifications.

Apart from the Marshmallow goodness, this update apparently comes with AT&T specific changes as well. For instance, changes have been made to add video calling support and full preload for Amazon.

At the same time, AT&T has removed the following apps — Keeper, AT&T Live and FB Messenger from the firmware. AT&T Mail and YP Mobile, on the other hand, have been shifted to a Virtual Preload.

Furthermore, the key Marshmallow-specific feature is the Doze Mode, which saves the stand-by battery life of the handset by putting it to deep sleep when not in use for a stipulated period of time. Other features include Google Now on Tap to enable contextual search depending on the content displayed on the phone’s screen, changes to app permissions and addition of a bunch of creative emojis.
