Samsung has done a great job of updating its devices to One UI 3.0 based on Android 11 over the last few weeks. The software update has already rolled out to several Galaxy devices, and we expect Samsung to maintain its fast rollout schedule for its next software release — One UI 3.1. For the unaware, One UI 3.1, which is also based on Android 11, debuted with the Galaxy S21 series earlier this month, and it packs quite a few new features and changes. The update has already started rolling out to the Galaxy Tab S7 and Tab S7 Plus, and it should arrive on other Galaxy devices in the coming weeks. While you're waiting for the update to roll out to your device, here's a quick look at all the new software features and changes included in One UI 3.1.

Note: Not all of these features will be available on other Galaxy devices. To find out what features are headed to your device, be sure to thoroughly read the update changelog when the One UI 3.1 update arrives on your device! In addition, this post doesn't include some of the new features that are exclusive to the Galaxy S21 lineup.

New features in One UI 3.1

Google Discover feed integration

You can customize the stock launcher on One UI 3.1 to display the Google Discover feed on the minus-one screen. By default, the stock launcher is configured to show Samsung Free on the minus-one screen, but you can change that by following these steps:

• Tap and hold on the home screen to open the customization settings.
• Swipe all the way to the left until you see the following page
• Tap on the Google Discover option

The Google Discover feed will then show up on the minus one screen. You can switch back to Samsung Free anytime you want by following the same steps. You can also turn off the feature altogether by tapping on the toggle in the top right corner.

Google Home Device Controls

Samsung has integrated Android 11's Device Controls feature into the 'Devices' option in quick settings. With this feature, you can add smart home devices from Google Home and other compatible smart home apps to this menu. The feature lets you easily control all your connected Google Home devices without opening up the Google Home app. You can follow this guide to access Google Home Devices controls on Galaxy devices running One UI 3.1

Google Duo integration

Samsung has worked closely with Google to offer better Google Duo integration in One UI 3.1. The company's latest software release features seamless Google Duo integration in the stock dialer app. As you can see in the below screenshots, the three-dot menu in the stock dialer now has a new 'Make video calls using' option. Tapping on this option lets you select Google Duo as your preferred video calling service.

Once you select Google Duo as the default video calling service, you'll notice a new Google Duo button next to the call button on the dialer whenever you select a contact who's available on Google Duo. You can tap on this button to instantly start a video call with the contact.

Along with seamless Google Duo integration in the stock dialer, the Galaxy S21 lineup also supports Google Duo's auto-framing feature. The feature automatically keeps you front and center during video calls, eliminating the need to adjust the frame constantly. As of now, it isn't clear if the feature will roll out to other Samsung devices with the One UI 3.1 update.

Video call effects

While we're on the topic of video calling, let's take a look at another cool new feature in One UI 3.1 — Video call effects. The feature can be found within the 'Advanced features' section in the device settings, and it lets you automatically add cool background effects during video calls.

As you can see in the attached screenshots, the feature currently offers three background effects — Blur, Color, and Image. When enabled, the Blur option adds a background blur in the video calls, the Color option covers the background in a solid color, and the Image option covers the background with a custom image of your choice.

After you select one of the three options, you can tap on the 'Preview' button to see what the background will look like during video calls. The page also lists supported apps that will make use of the video call effects once the feature is enabled. For a demo of what this looks like, check out our dedicated article on the topic.

Remove GPS location data from photos & Private Share

During the Galaxy Unpacked event, Samsung talked about a new privacy-related feature for the Galaxy S21 lineup. The feature lets you easily remove location data from photos before you share them.

To do so, all you need to do is select a photo in the Gallery app, hit the share button, and then tap on the "Remove location data" option underneath the preview in the share sheet. Using this feature will strip the photo of location data like the latitude and longitude of where it was taken before it's shared.

To give you more control over the content you share, Samsung has also launched a new Private Share app. You can use it to share any file, including images, videos, and documents, and choose when to revoke access to the file. However, you first need to enable the app from the device settings. You can do so by heading over to the Biometrics and security settings and tapping on the new Private Share option. This will open up a new window that will let you add the Private Share app to the app drawer.

You can then open the app by tapping on the Private Share icon, tap on the 'Share files' button in the menu, and then select the recipient from the following screen. The app will then let you manually revoke access to the file at any time, or you can wait 2 days for the recipient's access to automatically expire. The new Private Share app works on all Galaxy devices running Android 9 or later, but both the sender and the recipient need to have the app installed on their device to share files.

Continue apps on other devices

If you're a part of the Samsung Galaxy ecosystem and use more than one Galaxy device regularly, then One UI 3.1 packs a cool new feature for you. The feature, called 'Continue apps on other devices,' can be found within the Advanced features section of the device setting. Once enabled, it lets you continue using an app on a different device that's signed in to the same Samsung account.

To continue using an app on a different device, all you need to do is open up the Recents screen on the other device and tap on the new icon. You can also use this feature to copy text, images, and more on one device and paste them on the other device. But you'll need to have this feature enabled on both devices for it to work as expected. You'll also need to turn on Bluetooth on both devices and ensure that they're connected to the same Wi-Fi network.

It's worth noting that this feature currently only works with the Samsung Internet and Samsung Notes apps. But Samsung may expand support to more apps in the near future.

Eye comfort shield

Eye comfort shield is a new feature in One UI 3.1 that builds upon the Blue Light Filter feature found on previous versions of the software. The feature can be found within the Display settings, and it lets you limit exposure to blue light by altering the display colors.

As you can see in the attached screenshot, the feature includes two options — Adaptive and Custom. The Adaptive option automatically adjusts the colors based on the time of the day to limit blue light. While using this feature, you'll notice minor color adjustments during the day and significantly warmer colors at night.

The Custom option lets you manually select the color temperature based on your preference. It also lets you set up a schedule to enable your custom color settings automatically. You can either have your custom color settings enabled all the time, vary from Sunrise to Sunset, or change at a specified time.

Object eraser

The Galaxy S21 devices also come with a new Object Eraser feature in the Gallery app. The feature lets you easily remove unwanted objects from your photos. However, the feature isn't enabled by default. To enable it, you'll need to tap on the three-dot menu button in the top right corner of the editor. In the drop-down menu, you'll have to select the new Labs options and then tap on the toggle next to the 'Object eraser' feature on the following page.

Once the feature is enabled, you'll see a new icon in the image editor with a prompt highlighting its functionality. To remove an object from your image, tap on the new icon and then select the unwanted object on the following page. The feature will then highlight the selected object, and you can tap on the 'Erase' button to remove it. In my testing, I found that the feature does an 'OK' job of removing objects. Your mileage may vary.

New Camera features in One UI 3.1

Director's view

The new Director's view feature on the Galaxy S21 lineup lets you capture videos from all the cameras on the device simultaneously. On the Galaxy S21 Ultra, this means that you get access to four different camera angles at the same time on the viewfinder, and you can switch between them seamlessly.

Vlogger view

The Vlogger view on Galaxy S21 devices lets you use the front and rear camera simultaneously. This is great for vloggers, as it lets them capture their reactions while recording something from the rear camera at the same time. It's worth noting that while Samsung talked about the feature during the Galaxy Unpacked event, I wasn't able to find it on my review unit.

Single Take 2.0

Samsung has updated the Single Take feature with the launch of the Galaxy S21 lineup, and it now lets you capture more frames each second. On top of that, Single Take 2.0 also records slow-motion clips. Furthermore, the feature now also lets you choose the type of shots you wish to capture. You can tap on the new arrow icon in the top right corner and then select shots from the following menu. The feature offers 6 options to choose from — Filtered videos, Filtered photos, Speed effect clips, Portraits, Wide/cropped shots, and Highlight videos.

Focus enhancer

The camera app on the Galaxy S21 Ultra also includes a Focus enhancer option that pops up in the bottom right corner of the viewfinder while using the primary 108MP camera. The toggle only shows up when you're trying to take a picture of a nearby object, and it ensures that the entire object remains in focus.

This is one major issue I had with the primary camera on the Galaxy Note 20 Ultra, and I'm glad Samsung has added this new feature to address that. I sincerely hope Samsung rolls it out to the Galaxy Note 20 Ultra and the Galaxy S20 Ultra with their One UI 3.1 update.

You can read about these new productivity features in more detail here.
