Google Duo: Understand Google’s Video & Voice Call App

Google Duo is free to use and work across iOS and Android devices – unlike Apple’s FaceTime. Duo relies on the phone number, enables you to reach people in your phone’s contacts list. It allows end-to-end encryption and has nifty features like Knock Knock, which will enable you to see a live video of the caller before answering it.

It’s effortless to use, too, because the app’s interface is straightforward. Here’s how Duo operates, including how to get initiated and whether it’s safe to use.

Google Duo’s main interface is a cover that is split into two, with the top half revealing you what your camera views and the bottom extending up your groups or contacts. In addition, there’s a search bar at the head and a menu for reaching settings.

Video Calling

Each time you open Duo, you’ll notice the camera view with the contacts, search bar, and groups below. To commence making a video call, type in the connection you need to video call in the search bar > select the title from the list > tap on the ‘Video call’ icon in the center at the bottom of your screen.

When a person video calls you, and you happen to be using your phone, you’ll notice an incoming video call screen, which includes a view of whatever their camera sees, the name or the number of the person, and buttons to either reply or ends the video call. If you’re not utilizing your phone, you may receive a notification that states a video call is incoming, but that depends on your notification preferences. When you or the person end a call, you will be taken back to the camera view/search bar and the ‘Create Group’ button screen.

Manage Preferences

While on Google Duo’s main app interface, tap the three-horizontal dots key in the upper right-hand corner. You’ll then view alternatives to go to Settings, Privacy in Duo, Help, including Feedback. Hit the Settings option. Below this menu, there are various settings you can change, including the ability to turn off Knock Knock and Low-light mode. You can also check your mobile data usage, allow your phone to vibrate while ringing (Android only), unregister the phone number, append a Google Account, and block numbers, with different things like Siri Shortcuts for iOS users. There’s also the capacity to turn on features like Duo Moments, which arise in and take in-call photos shared with the group.

Extra Features

Duo has a Knock Knock feature that lets you see a live video before you reply. You can stop this feature under the ‘Settings’ menu within the app. In addition, Duo has a feature called Low-light mode that will make you more visible to the person on the other end of a video call if you are in poorly lit surroundings. You can disable the feature mentioned above under the ‘Settings’ menu mentioned in the ‘Manage Preferences’ section above.

Google Duo extends group video calls for up to 32 people. To create a group, tap on ‘Create Group’ at the bottom of the Google Duo screen and select the contacts you want to add. Like FaceTime and WhatsApp, Duo offers voice calling as well as video calling. You can also send recorded messages. The Duo requires your phone number. The app allows you to reach people in your phone’s contacts list. No separate account is needed.
