TouchWiz

TouchWiz is touch interface created and developed by Samsung Electronics with partners, featuring a full touch user interface. TouchWiz is available only on Samsung phones. 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 Samsung-made apps preloaded (except Galaxy S6 and S6 Edge, which have removed all Samsung pre-loaded apps, leaving one with Galaxy Apps, to save storage space, due to the removal of MicroSD).

The latest version of TouchWiz is TouchWiz 6.0, which is on the Samsung Galaxy J1 mini Prime and TouchWiz Nature UX 5.0 on the Samsung Galaxy J3 (2016). feature a more refined user interface as compared to the previous versions, on Samsung's older flagships released prior to Galaxy S5's release. The status bar is now transparent during home screen mode in TouchWiz Nature UX 2.0 and TouchWiz Nature UX 2.5. In TouchWiz 4.0 on Galaxy S II and the Galaxy Note (both later updated to Nature UX), some of the features added include panning and tilt, which makes use of the accelerometer and gyroscope in the phone to detect motion.

TouchWiz is used by Samsung's own proprietary operating systems, Bada and REX, as well as phones based on the Android operating system. It is also present in phones running the Tizen operating system.

TouchWiz was a central issue in Apple v. Samsung.
