Sprint's Galaxy S6 got Marshmallow in March, and Verizon and T-Mobile followed in April. After months of waiting, AT&T is finally rolling out the Android 6.0.1 Marshmallow update to Galaxy S6 and Galaxy S6 Edge owners. New additions include UI tweaks throughout, new emoji, an updated Samsung browser, and Google Now on Tap. AT&T is also removing Keeper, AT&T Live, and Facebook Messenger, and moving its AT&T Mail and YP Mobile apps to virtual preload so you can uninstall them freely. The updates are available for both AT&T's Samsung Galaxy S6 and S6 Edge devices, and they're around 1.5GB in size.
