TouchWiz is a discontinued user interface developed by Samsung Electronics with partners, featuring a full touch user interface. It is sometimes incorrectly referred to as an operating system. TouchWiz was used internally by Samsung for smartphones, feature phones, and tablet computers, and was not available for licensing by external parties. The Android version of TouchWiz also comes with the Samsung-made app store Galaxy Apps. It was replaced by Samsung Experience in 2017 with the release of Android 7.0 "Nougat".
