TouchWiz was the synonym for Samsung’s custom user interface on Android smartphones. Samsung has yet to announce it, but according to Android 7.0 Nougat beta builds, the user interface TouchWiz is about to get replaced by the new branding – Samsung Experience.
Although the user interface will have a brand new name, don’t expect any drastic changes. Except for a few new features that come with Android 7.0 Nougat, and maybe a few others that Samsung will include, the user interface will mostly look the same. The update is expected to start rolling out by the end of the year, or early in 2017.
