One UI version 4 was officially tested for several weeks before the official implementation of this version of the system to Samsung's phones. The company did not talk about the software release date for a long time, but a few dozen hours ago the list of planned system upgrades for the equipment of this manufacturer leaked to the Internet. At least its beginning turned out to be correct as Samsung has officially launched One UI 4 for the Galaxy S21 series phones.
Some users who have Galaxy S21, Galaxy S21+ or Galaxy S21 Ultra phones can download the new version of the system today, but Samsung's release of One UI 4 for all users will take several weeks. The new version of One UI introduces, among other things, notifications about the use of the microphone and camera by specific applications, a new privacy menu containing all the necessary information in one place, and moreover, Samsung has updated the appearance of widgets and added new emoji and gifs available via the keyboard.
