One UI 3.1 updates for your Galaxy phone

A bunch of new photo and video features are waiting for you on Note20, S20, or S21 devices with the One UI 3.1 update. If you love filming on the go, you can now capture your voice through both your Galaxy earbuds and phone with the Multi mic recording feature. The Object eraser tool lets you remove items from your photos with just a quick tap. And when you’re sharing your photos with friends, use the new Private Share option to control how your photos are received by others. Some previous features have received improvements as well, like taking photos with Single Take and protecting your eyesight with Eye comfort shield.
Note: Supported features may vary by device and software version.
Object eraser
Do you need to remove something from your photo, like a book or a chair in the background? The Object eraser tool on One UI 3.1 allows you to do just that. If you tap the area containing the item you’d like to remove, the tool will delete it without changing anything else in the photo. Before you can use the Object eraser, you'll need to add the tool.
Navigate to and open Gallery, and then select the photo you want to edit.
Tap the Edit icon at the bottom (it looks like a pencil), and then tap More options (the three vertical dots).
Tap Labs, and then tap the switch next to Object eraser to add it to your editor.
Tap Back, swipe left on the bottom of the screen, and then tap the new Object eraser icon. It looks like an eraser.
Tap an object or section of your photo, and then tap Erase to remove it. Tap the checkmark to save the image. If you are not happy with how it looks, tap the X icon and then try again.

Multi mic recording
The new Multi mic recording feature on One UI 3.1 devices lets you simultaneously record audio through your phone and a connected Bluetooth device, like your Galaxy Buds Pro. This feature will ensure your voice carries clearly in your videos, even if you’re doing something else at the same time, like playing a game or listening to music. You’ll need to use Pro Video mode to access Multi mic recording.
Using two fingers, swipe down from the top of your phone’s screen to open Quick settings. Touch and hold the Bluetooth icon to open the Bluetooth menu.
Make sure your buds are synced and appear under Paired devices.
Next, navigate to and open the Camera app, and then tap MORE.
Tap PRO VIDEO, and then tap the Microphone button.
Choose how you'd like to record audio from the available options, i.e. BT Mix will use both the phone's microphones, and your headset microphones.

Private Share
If you’re concerned about some of the photos you’re sharing, you can use the Private Share option on your One UI 3.1 device. This will prevent recipients from sharing your photos in the future. You can also remove location metadata from photos that you’re sending to others.
Note: Your phone needs to have an active SIM card to use Private Share.
First, navigate to the photo you’d like to share, and then tap the Share icon.
To remove location information from the photo, tap Remove location data at the top of the screen.
Swipe to and tap Private Share to choose a recipient to share your photo with. You can search for a contact or choose a recent contact.
Note: To add a shortcut to your Apps screen, tap the Settings icon and then tap the switch next to Add Private Share to Apps screen.
Tap the name of your chosen contact, and then tap Send.

Single Take
If you’d like to capture several photos of your friends or a few selfies at once, you can use the Note20's or S21’s Single Take. Along with the photos, this feature will generate a short video for you too.
With the One UI 3.1 update, S20 users can start enjoying Single Take’s improved options as well, like speed effects and facial detection.

Eye comfort shield
Sometimes, your phone screen’s brightness can be a little too much for your eyes, especially at night. To protect your vision, you can use Eye comfort shield (or Blue light filter on previous OS versions). Eye comfort shield can help you fall asleep easier by changing your screen to a warmer tone automatically as the day progresses. When you look at your phone at night, your eyes will adjust to the screen’s color without getting irritated.
