context_page_description: 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.
context_section_description: The second version of TouchWiz was released in 2011, to support Android Gingerbread and Android Honeycomb (2.3 - 3.2.6). The Galaxy S II was the first device preloaded with TouchWiz 4.0. This version includes better hardware acceleration than 3.0, as well multiple touchscreen options involving multi-touch gestures and using the phone's accelerometer. One such feature allows users to place two fingers on the screen and tilt the device towards and away from themselves, to zoom in and out, respectively. "Panning" on TouchWiz 4.0 allows users to scroll through home screens by moving the device from side to side.
