What's New

One UI 4.1 Update
One UI 4.1 brings you the latest features for your Galaxy devices. More intuitive, more fun, more secure, and easier than ever.
Check out the changes below.

Camera
It's easier than ever to capture great photos and videos.
More options for portrait videos
Capture great portrait videos even when your subject is far away. You can now record portrait videos with the 3x lens on the rear camera in addition to the 1x lens.
Zoom in farther in Pro and Pro video modes
The telephoto lens is now supported in Pro and Pro video modes so you can capture clearer images and videos of far away things.
Get the full director’s view
You can save your director’s view videos with separate front and rear videos so you can edit them later, even after you’re done recording. When you play them back in the Video player, you can switch between different views such as split-screen or picture-in-picture.

Gallery
Do more with your memories. Gallery brings enhanced features for remastering and organizing your pictures and videos, and sharing is now easier than ever.
Powerful remastering
Make your photos look better than ever. Sharpen blurry faces, fix distortion on TVs or computer screens, and increase brightness and resolution.
More suggestions
Get help creating artistic portraits and exciting highlight reels. Gallery will suggest the best effects for your pictures.
Add portrait effects
You can now add background blur to any picture with a person in view.
Portrait relighting
Adjust the lighting for portraits, even after you've taken them, to make sure you always get the perfect shot.
Convert unnecessary motion photos to still images
Save storage space by converting motion photos to still images. Gallery will suggest pictures where motion isn't necessary, such as documents.
Share albums as links
No need to invite people to shared albums individually anymore. Just create a link that can be shared with anyone, even if they don't have a Samsung account or Galaxy device.
All your invitations together
Easily accept invitations to shared albums, even if you miss the notifications. Invitations that you haven't responded to yet will appear at the top of your shared album list.
Create time lapse videos
Turn a picture into a vivid 24-hour time-lapse video. A button will appear for pictures of scenery including the sky, bodies of water, mountains, or cities. Your video will appear as if an entire day has passed.

AR Zone
Express yourself like never before in augmented reality. Create your own emojis, stickers, doodles, and more.
More decorations for your emoji stickers
Show your own unique style by adding GIFs from Tenor as decorations for your custom AR emoji stickers.
Add more to your AR doodles
Create 3D stickers by scanning real-world objects, then add them to your AR doodle. You can also add GIFs from Tenor and Giphy.
Background colors in mask mode
Keep the focus on your AR emoji while wearing it as a mask. Choose from a variety of colors to use as your background.

Smart Widget
Your Home screen widgets just got smarter. Just choose the widgets you want and let your Galaxy do the rest.
Group widgets together
Save space on your Home screen by combining multiple widgets into one Smart Widget. Swipe left or right to scroll through your widgets, or set them to rotate automatically to show you the most relevant information based on your activity.
Get suggestions on your Home screen
Your Smart Widget will tell you when it's time to charge your Galaxy Buds, when it's time to get ready for an event on your calendar, and more.
