Make Quality Video Calls With Google Duo

Technology is changing the way we communicate - it's becoming more easier with innovative applications. Talking to people and seeing them at the same time despite being in a distant location improves communication. Google is helping us communicate better which has been marked by the release of Duo.

Duo is a simple, high-quality video calling mobile chat app available on both Android and iOS. Duo will be competing with other instant messaging apps such as Facebook Messenger, Skype, IMO, WhatsApp and FaceTime. But unlike others, Duo is a standalone video calling app, it is purposed only for video chats.

Duo has its unique features which include a simple interface, Knock Knock - a live preview feature that enables you to see the caller before you pick. Duo is a cross-platform app with high-quality video. Duo can dynamically adjust the video and audio quality to suit whatever kind of connection you’re on and can maintain the call even when switching from Wi-Fi to cellular and vice versa.

Many Google apps require signing in with a Gmail account but Duo requires only your mobile phone number. This is so because duo works with phone numbers and not username or password. It like directly calling a number from your phone contact. The recipient must also have the Duo app.

How To Begin With Google Duo

Knowing what Google Duo does, the next step is to begin using it. Duo is very easy to set up. Go to Playstore or App store and download it. After that, follow these steps below.

==> Launch the App. The Duo logo will display for some few seconds.

==> You'll get a welcome message, also requesting you to agree to its Privacy Policy and Terms of Service. You must click on 'I AGREE' to proceed further.

==> Input your phone number and click on 'NEXT'.

==> A verification code will be sent to your phone number by SMS. Type the code. If you didn't receive the code via SMS, then try the CALL ME option.

==> After verifying your phone number, click on the video icon to initiate a video call.

You will see a list of your contacts on DUO and you can invite the people that are not on Duo.

==> To adjust the settings, Click on the three dotted lines at the upper right.

You can decide to turn off vibration, remove live preview (knock knock), unregister your number or block numbers and set a limit on mobile data usage.

Note: Knock knock is available currently only on Android.


If you’re having problems verifying your phone number through Duo, try the following steps to finish verifying your phone number:

1. Check your phone number

Make sure your phone number was entered correctly with the right country code.

2. Check for a good Wi-Fi or mobile data connection

Check your settings to make sure WiFi or mobile data is turned on and airplane mode is turned off. Move to where you have a better mobile data connection. Your network signal icon should have at least 1 bar. Test your connections by visiting a website.

3. Make sure that you can get the SMS verification code

Check that your cell signal is on and that your airplane mode is turned off. If your signal is weak, move to where you have a better cell signal. Your network signal icon should have at least 1 bar. Test your connections by sending yourself an SMS.

4. Request a new verification code

On the verification code screen, you can ask for the code again.

If you don’t receive a text message, tap Resend SMS.

If you have a cell connection and aren't getting the SMS, request a call by tapping Call me.

5. Try fixing the app

Quit & restart: Go to your device’s Settings >Apps > Duo > Force Stop. Open Duo again. Uninstall and re-install the app: Try uninstalling Duo. Then re-download Duo and open the app. Restart your phone: Try turning your phone off and turning it back on. Then open Duo again.

If none of the above solve the issue, you can ask questions in the Duo Help Forum.
