Samsung Galaxy Note 7, the latest iteration in the Note series is a powerful phablet with a stylus or the S-pen. S-pen adds lots of functionality to the device and the newer S-pen is now even waterproof. So you can take down notes even underwater, even though one might never do that. The Note 7 comes with the latest version of TouchWiz UI which has been named GraceUI. Some may find it pleasing to the eyes due to the less use of vibrant colors while others might not.

The newer TouchWiz UI is still based on Android Marshmallow but the update might arrive within a couple of months. Though the newer version of TouchWiz UI has been trimmed down a lot there might be some carrier bloatware present on your device. To get rid of bloatware you would need to root your device. Or, if you want to tinker with the user experience of your device rooting is the first step you should take. Given below is the step by step guide to root your AT&T Galaxy Note 7.

  1. Thanks for sharing this, very helpful. I was able to put the AT&T ROM on with Odin 3.12.

    Unfortunately I am unable to add Super User Permissions though. When running the adb shell the su command returns not found and if I go to the sh directory I get ‘permission denied’ any thoughts on things to try?
