Google Duo was a video and audio calling service that competed with FaceTime from Apple, WhatsApp and Messenger from Facebook, and Skype from Microsoft. In contrast to Apple’s FaceTime, Duo didn’t cost anything to download or use, and it was compatible with both iOS and Android devices. When Google integrated Duo and Google Meet in August 2022, the latter service became branded solely as Meet.
Here, we’ll break down the current procedure in detail while also providing historical context for those who are curious.
To Whom Do We Owe the Transition from Google Duo to Google Meet?

It makes sense to consolidate Google’s two video-calling apps, Duo and Google Meet, which were previously in an odd form of rivalry, as the company did at the beginning of June 2022.
The integration then started around the beginning of August 2022. However, the procedure wasn’t as streamlined as we had hoped. While the former Google Hangouts app has been retired, the newer Google Meet app has been renamed Duo (original).
Google has rebranded Duo without changing any of the app’s core functionality, but has added all of Meet’s features. However, the original Meet does not yet have all of Duo’s features and will likely be phased out in the future.
Check out our Google Meet section if you’re curious about the inner workings of the latest edition of Google Meet (and Duo). The following describes the previous operation of Duo before the merger.

The function of Google Duo, please.
Stepping into Action
Go ahead and get the Google Duo app on your iPhone or Android device.
I accept Google’s Terms of Service and Privacy Statement.
Set the permissions for Duo to access your device’s microphone and camera and receive notifications.
Ensure your phone number is correct.
Enter the one-time code that was delivered to your cell phone through text message.
Soon after, the app’s primary user interface will load.
The main interface of Google Duo consists of a split screen, with your camera feed in the upper half and your contact lists in the lower half. Additionally, a search bar and settings menu can be found at the very top of the page.
Using a Camera to Communicate
When you first launch Duo, you’ll see the camera view, followed by the search bar, and then your contacts and groups.
Start a video call by searching for the person you want to talk to, tapping their name in the results, and then tapping the video call icon in the middle of the bottom of your screen.
If you use Google Voice for the first time, the search engine will “Smile! This is Knock Knock Time “with a message saying that their phone will vibrate and display your number if your friend has you saved as a contact. However, your friend cannot see you while they are calling you thanks to this function. So, when you make a video call to a friend, a screen will appear to warn you that your video is visible, followed by the person’s name or number and an end button superimposed on the view from your camera (likely you).
When a buddy video calls you, you’ll get an incoming video call screen that offers a preview of what your friend’s camera is seeing, the person’s name or number, and options to answer the call or end it. Depending on your settings, you may be alerted to an incoming video call even if you aren’t actively using your phone.
The real video call screen, which includes a view of whatever your buddy’s camera sees and four buttons, is displayed if you accept or your friend accepts a video call from you. These controls include a volume slider, a camera switch, a night mode toggle, and a call end button. The camera view of your friend can be shrunk to a circular thumbnail, and you can tap the thumbnail to expand your view. To put it simply, everything is easy to understand.
When a call is terminated by either party, the user is returned to the main screen with the camera, search bar, and “Create Group” button.
Take note that you can welcome friends to Duo and search for contacts by name or number using the same search box. Even though it may seem apparent, remember that your friends will need to instal Duo in order to make video calls to you using Duo.
Keep Tabs on Inclinations

Google Duo‘s primary interface (the camera view/search bar and ‘Create Group’ button screen) may be navigated by tapping the three horizontal dots button in the top right corner of the screen. The next screen will let you choose between visiting Settings, Privacy in Duo, obtaining assistance, or providing feedback. Click the gear icon and select Settings.
Several options, such as the ability to disable Knock Knock and Low-light mode, can be found here. In addition to features like Siri Shortcuts for iOS, you may restrict your mobile data, turn on vibration when ringing (Android only), delete your phone number, link your number to a Google Account, and block unwanted calls.
Turning on features like Duo Moments allows users to appear in and snap in-call images that may be shared with the group.
