After T-Mobile now AT&T is giving update to Galaxy Note 2 with multi window feature. AT&T announced this today and it will be receiving an over-the-air update with multi-window support tomorrow.
Multi Windows view feature which allows users to open and work on different windows at once. For Example i’m reading news on one side and on other side i’m watching you tube. Currently this feature is available only for Samsung, Google and other third party apps like Facebook and Twitter.
