Learn about Google Duo
Set up Google Duo
Google Duo is a free service. Before you set up and use Google Duo you need:
- A phone number
Access to a phone that can receive SMS messages
To use Duo across multiple devices and platforms, you need a Google Account.
Make video calls to your contacts
Get great video and audio quality
To make sure you're looking and sounding your best for a video call:
- Check your lighting. If you're in low lighting, Duo will adjust the brightness of your video. If you want to turn the setting off in a call, tap the screen and turn off Low Light mode . Or, you can turn it off in Settings.
- You can switch camera views to show yourself or what you're looking at in front of you. If the camera points to your face, hold your device at eye level to help others see your face.
- Make sure nothing (ex: your finger) is blocking your device's camera or microphone.
Connect to Wi-Fi before calling. Using Wi-Fi will save your data usage and also could be a better video connection. If you can't, turn on your data.
See a video preview with Knock Knock
When you call a contact using Duo, the other person can see live video of you while the device rings if they have you as a contact. You won't be able to see the person you're calling until they answer.
You can also turn Knock Knock off.
Move your picture during a video call
When you make a Duo call, your face shows up in a small rectangle on the screen. To move it, touch and hold the rectangle, then swipe your finger across the screen to another corner. To show your face on the entire screen, tap your picture.
Use less data
For unwanted calls, you can also block a phone number from calling you.
If you're having problems with your video call, try fixing your call quality.
