Washington: South Korean tech giant Samsung unveiled the new One UI Watch software for its upcoming Galaxy Watch portfolio at MWC 2021 but did not reveal the next Galaxy Watch 4. Samsung while unveiling One UI Watch at the event stated that the new interface will make its debut on a new Galaxy Watch “later this summer,” reported Mashable. The new smartwatch interface, One UI Watch, combines the best features of Wear OS and Tizen. During the event, the South Korean company demonstrated what the actual software will look like. It showed how settings on the smartphone will mirror those on the watch. The experience, it said, will be seamless. The tech giant also teased new integrations with apps like Starva, Adidas Running, and Spotify, the latter of which will bring offline playback to Wear OS. Samsung also said that it will open its watch face design tool to Google developers, allowing them to create, unique watch faces.
