TouchWiz


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.

History

Overview

The first, original edition of TouchWiz, released in 2008. This 1.0 version is officially launched with the original Samsung Solstice in 2009. 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 feature a more refined user interface as compared to the previous versions found on Samsung's older phones 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, some of the features added include panning and tilt, which makes use of the accelerometer and gyroscope in the phone to detect motion.
TouchWiz was abandoned by Samsung in late 2016 in favor of Samsung Experience. 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 the legal battle between Apple and Samsung.

TouchWiz 1.0

This was the original edition of TouchWiz, released in 2008, with pre-introduction on SGH-F480. This version is officially launched with the original Samsung Solstice in 2009. Various versions of TouchWiz 1.0, with different features, were used on Solstice's siblings such as the Samsung Eternity, Impression, Impact and Highlight.

TouchWiz 2.0

This was the original second edition of TouchWiz, released in 2009. This version premiered with the Samsung Solstice 2 in 2010.

TouchWiz 3.0

Released in 2010, to support Android Froyo. This version premiered with the Samsung Galaxy S. A lite version of TouchWiz 3.0, with reduced features, was used on the Samsung Galaxy Proclaim.

TouchWiz 4.0

The second version of TouchWiz was released in 2011, to support Android Gingerbread and Android Honeycomb. 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.

TouchWiz Nature UX

The third version of TouchWiz was renamed to TouchWiz Nature UX. It was released in 2012 and supported Android Ice Cream Sandwich. The Galaxy S III, Galaxy Star and Galaxy Note 10.1 were the first devices preloaded with this version, although a lite version was used beforehand on the Samsung Galaxy Tab 2 7.0. TouchWiz Nature UX contains more interactive elements than previous version, such as a water ripple effect on the lock screen, and "smart stay", a feature which uses eye tracking technology to determine if the user is still watching the screen. To complement the TouchWiz interface, and as a response to Apple's Siri, this version introduces S Voice, Samsung's intelligent personal assistant.
The colour palette of the user interface has been adapted to the colours of nature, prominently green and blue, to visually represent the slogan “Inspired by Nature”.
This version of TouchWiz also utilized many colour gradients.

TouchWiz Nature UX 2.0

This version supports Android Jellybean and was released in 2013; the Samsung Galaxy S4 was the first device to use TouchWiz Nature UX 2.0. Even more eye tracking abilities were introduced with this version, such as "smart scroll", which allows users to scroll down and up on webpages by tilting their head downwards and upwards, respectively.
The on-screen buttons for photo, video and modes now have a metallic texture, and both photo and video recording modes are combined into one viewfinder page rather than separared by switching modes.

TouchWiz Nature UX 2.5

TouchWiz Nature UX 2.5 was released in 2013 to support the last updates to Android Jellybean, and was first used on the Galaxy Note 3 and the Galaxy Note 10.1 2014 Edition. This version completely supports the Samsung Knox security solution, as well as multi-user capabilities. The camera was also improved in this update: shutter lag was reduced, and features like a 360° panorama mode were added. The settings menu is equipped with a new search feature.
A vertical one-handed operation mode has been added for the Galaxy Note 3. It can be accessed with a swiping gesture on either side of the screen and allows variably shrinking the simulated size of the screen. It also is equipped with on-screen navigation and volume keys.

TouchWiz Nature UX 3.0

This update was released in 2014 to support Android KitKat. It was first seen on the Galaxy S5, Galaxy K Zoom and the Galaxy Note Pro 12.2. It later appeared on the Galaxy Alpha.
The home screen and settings menu were made more user-friendly with larger icons and less clutter. Also, icons in the context menus were removed for minimalism, and any disabled options, where previously they would have been visible but unusable, now do not show up at all.
The one-handed operation mode available on the Galaxy S5 allows setting shortcuts for apps and contacts.
The new colour palette utilizes oceanic colours to reference the Galaxy S5's water resistance.
Some budget devices, such as the Samsung Galaxy Trend 2 Lite, Galaxy J1 Ace, Galaxy V Plus and Galaxy Grand Neo Plus feature a reduced version of TouchWiz Nature UX 3.0 called "TouchWiz Essence UX", which is adapted for devices with less than 1 GB of RAM. 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.
The redesigned settings menu has flat icons instead of previously used self-coloured clip-art, and is equipped with three distinct viewing modes: Grid view, List view and Tab view.

TouchWiz Nature UX 3.5

This is a slightly modified version of TouchWiz Nature UX 3.0, released in 2014 for the Galaxy Note 4, Galaxy Note Edge and Galaxy A-series. Most of the changes made were minor, aesthetic ones, including an overhaul of the cluttered settings menu, the inclusion of quick setting shortcuts and centralization of the lock screen clock. However, the camera application was stripped down to its most basic features, removing features such as the WiFi Direct-powered remote viewfinder, nonetheless gaining an AF/AE lock feature accessible through tapping and holding in the camera viewfinder.
The "grid view" setting menu viewing mode introduced in TouchWiz Nature UX 3.0 has been removed. Menus and system applications use white instead of dark backgrounds.
The ability to use shortcuts for apps and contacts in the one-handed operation mode has been removed.

TouchWiz Nature UX 4.0

This version comes with Galaxy S5, and so supports Android Lollipop and was released in 2015. Update 4.0 eventually became available to the Galaxy S4, Galaxy Note 3 and Galaxy S5 and Note 4, and other Lollipop-compatible devices, but with fewer features.
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. TouchWiz Nature UX 4.0 also included a visual overhaul for the whole system, changing the black background in system apps to a white theme, similar to TouchWiz UX 3.5 seen on the Note 4 & A series. 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.

TouchWiz 5.0

With TouchWiz 5.0, Samsung reverted to the earlier, simpler naming system, without the "Nature UX" infix, to reflect aesthetic changes. This version was released in 2015 primarily for the Samsung Galaxy S6, and supports later updates to Android Lollipop. This update cleaned up the user interface, reduced the number of duplicate functions, and used brighter and simpler colours with icon shadows. Many icons in top bars have been replaced with uppercase text labels such as "More".
A new version of TouchWiz 5.0 was released in September 2015 for the Galaxy Note 5 and S6 Edge+. The new version features updated iconography, with stock apps now featuring "squircle" icons instead of freeform, and a re-added single-handed operation mode that was removed on the Galaxy S6 after being available on the S5. However, it is opened with a triple-press of the home button instead of a swiping gesture, lacks on-screen keys and only has one fixed size.
Mid-range and entry-level devices feature a version named TouchWiz Essence 2.0. It is similar to TouchWiz 5.0 but icon shadows are not included along with or without Theme Support. It is comparatively lighter, faster and featured on devices such as the 2016 A series, Galaxy A8, Galaxy S5 Neo, tablets and the J series devices which run Android Lollipop. It also doesn't feature the Sparkling Bubbles lockscreen effect exclusive to Galaxy S6 devices and the Note 5.
Galaxy S6 user reports suggest that the frame skipping and still frame image extraction features have been removed from Samsung's video player software.

TouchWiz 6.0

This version of TouchWiz began during initial beta testing of Android Marshmallow on the Galaxy S6 in December 2015, for users who had signed up for the beta program, and became formally available in February 2016. It features a redesigned notification drop-down and colour overhaul, replacing the original blue and green hue to white. This version also removed the weather while centring and enlarging the clock on the lock screen, as well as bringing back the ability to customize the shortcuts on the lock screen. Icons are slightly modified with a flatter look, removing the shadows that featured previously. The Smart Manager was removed as an app, and was moved to a settings option instead.
On this version, Samsung also added the ability to 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.
TouchWiz 6.0 also includes Google's additions to Android: Doze and App Standby to improve battery performance, Now on Tap to quickly access the intelligent personal assistant Google Now, and Permission Control to limit the permissions granted to a particular application.

TouchWiz Grace UX

First released with the Samsung Galaxy Note 7 for Android Marshmallow, the Grace UX was named after the device's codename, and eventually made its way to older devices, including the Galaxy Note 5 through an update, the Galaxy S7 and S7 Edge through the official Android Nougat update. The Grace UX features a cleaner, flatter look to iconography and extensive use of white space. TouchWiz Grace UX devices also benefit from the Secure Folder functionality, which enables users to keep certain data, and even apps, behind a secure password.
In addition, for most countries, all the languages that were absent from previous versions will be available in this release, starting with the Galaxy Tab S3.
