TouchWiz was used internally by Samsung for smartphones, feature phones and tablet computers, and was not available for licensing by external parties.
[4] TouchWiz version 1.0 was officially launched with the original Samsung A887 Solstice,[5] a phone released on AT&T in the United States in 2009.
This version includes better hardware acceleration than 3.0, as well multiple touchscreen options involving multi-touch gestures and using the phone's accelerometer.
[9] A multi-touch magnification feature and a picture-in-picture mode ("pop-up play") have been added to the precluded video player, as well as panning and zooming motion gestures in the gallery software.
[10][11] To complement the TouchWiz interface, and as a response to Apple's Siri, this version introduced S Voice, Samsung's Virtual assistant.
Other additions and accessibility improvements are "easy mode", a simplified home screen option with larger icons, "smart rotation", where the screen rotates after the orientation of the user's face detected through the front camera, a low-light shot mode, the ability to adjust the volume of each side of headphones separately, a "reader mode" for Samsung Internet (formerly known as "S Browser") with adjustable font size, "Page Buddy", which can detect the user's intended action such as opening the music player when plugging in earphones, and the ability to read the news feed from Facebook in particular directly from the lock screen well before common lock screen notifications were released with Android 5.0 "Lollipop".
[14][15] This version supports Android Jelly Bean (4.2.2) and was released in 2013; the Samsung Galaxy S4 was the first device to use TouchWiz Nature UX 2.0.
The camera was also improved in this update: shutter lag was reduced, and features like a 360° panorama mode were added.
[20] To the existing split-screen feature, the abilities to drag and drop items in between and open select apps twice was added.
Also, icons in the context menus were removed for minimalism,[24] and any disabled options, where previously they would have been visible but unusable (Graphical widget), now do not show up at all.
This version has an ultra-power-saving mode, which drastically extends the battery duration by making the screen grayscale, restricting the apps that can be used, and turning off features like Wi-Fi and Bluetooth.
This version of TouchWiz continued the design that was initially seen on the Galaxy S5, with slightly more rounded icons, but also incorporated Lollipop's additions and changes, such as making the notification drop-down menu merely an overlay instead of a full-screen drawer and colouring it neon blue.
The black theme had been in place since the original Galaxy S, because it reduced battery consumption as Samsung mainly uses AMOLED display technology.
It was changed because of a patent licensing deal with Google, which required that the TouchWiz interface follow the design of "stock" Android more closely.
[39][40] With TouchWiz 5.0, Samsung reverted to the earlier, simpler naming system, without the "Nature UX" infix, to reflect aesthetic changes.
This update cleaned up the user interface, reduced the number of duplicate functions, and used brighter and simpler colours with icon shadows.
However, it is opened with a triple-press of the home button instead of a swiping gesture, lacks on-screen keys (navigation, volume controls, app/contact shortcuts) and only has one fixed size.
Shortcuts on the left pane are no longer customizable, and the settings are on a separate page rather than on top of an active viewfinder.
This version was also released for the S5 It features a redesigned notification drop-down and colour overhaul, replacing the original blue and green hue to white.
On this version, Samsung also added accessibility options such as Show button shapes, where buttons are outlined with a visible border and a shaded background to increase contrast from the background, and the ability change the display density setting, although this was initially only accessible through a third-party app as the setting was hidden by the system.
An update to the Galaxy S7 and S7 Edge made it official, allowing users to change it under the display settings.
