TouchWiz (or Samsung TouchWiz) is the user interface created, designed and developed by Samsung Electronics with partners, featuring a full touch user interface. TouchWiz is available only on Samsung devices. It is sometimes incorrectly identified as an operating system. TouchWiz is used internally by Samsung for smartphones, feature phones and tablet computers, and is 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 One UI in 2018 with the release of Android 9 Pie.
