AT&T is the only carrier left that hasn’t added back the multi-window feature to their Galaxy Note II. We don’t know why it disappeared from the US models in the first place, but each one has been putting it back in through updates. AT&T is finally doing the same, releasing the update as an OTA tomorrow. It should be a small update, but it will add the coveted feature back and I’m sure will make a lot of customers happy. If you don’t get the notification immediately, check for updates Settings > About phone > Software updates. And if you don’t get it tomorrow, it may be rolling out slowly, so you should get it soon.
