TouchWiz is a front-end touch interface developed by Samsung Electronics with partners, featuring a full touch user interface. It is sometimes incorrectly identified as an operating system. TouchWiz is used internally by Samsung for sophisticated feature phones and tablet computers, and is not available for licensing by external parties. The Android version of TouchWiz also comes with Samsung-made apps preloaded.
