Samsung One UI 3.1 is out now -- check out every new feature

Samsung started rolling out its latest One UI 3.1 software update to select regions last week, bringing new features from the Galaxy S21 phone series to more devices, including the Galaxy S20 series, Galaxy Note 20 series, Galaxy Z Fold 2 and Galaxy Z Flip. 

Samsung never uses stock Android software, but instead puts its own spin on the design. In the early days of Galaxy phones, it was something called TouchWiz, which was heavily criticized by reviewers. In late 2018, Samsung unveiled One UI with the aim to make it easier for users to navigate their phones. The third generation of the software arrived in December along with Android 11.

One UI 3.1 includes the following new features, all of which are already available on Galaxy S21 phones: 

• Enhanced single take: An updated Single Take feature for phone cameras lets you capture multiple images and video clips by pressing the shutter button just once. The feature launched on the Galaxy S20, but the S21 line brought more effects. 
• Object eraser: The new intelligent photo editing tool cuts out any unwanted parts of your pictures, without manual editing. 
• Multimic recording: Record audio through both your phone and a connected Bluetooth device at the same time, for better quality audio and video.
• Eye comfort shield: This new setting automatically adjusts the blue light being emitted from your phone based on the time of day, which could help with eye strain. You can enable it from your Quick Settings panel. 
• Private Share: This feature lets you share encrypted files and set permission and expiration dates for the data, as well as grant read-only access.
