What is it, what is it for and how does the Google Duo video calling application work?

Without a doubt, the Google Duo video calling application is among the best applications to make video calls worldwide, being an alternative to using Google Meet for free.

In recent years, applications to make video calls have gained popularity, and of course, Google can not stand idly by. Downloading or downloading Zoom could not become the only option.

It is for this reason that it has been developing a very attractive application that is practical and easy to use. It’s called Google Duo.

Through this section we will be talking about the Google Duo video calling application, what it is for  and how it works.

What is Google Duo and what is it for?

The Google Duo video calling app is a simple video chat app that works on both iPhone and Android. This is part of understanding what the Google Duo video calling app is, what it is for, and how it works.

Introduced by Google in 2016, it is one of several chat and video apps offered by the search company.

It is designed to be a quick and easy video chat app like Apple’s FaceTime. But since it is cross-platform, Android and iPhone users can video chat with each other.

How does video calling work on Google Duo?

As soon as the Google video calling application opens, the front camera is activated. This can be very annoying for some users.

Most video chat apps activate the camera (and sometimes even ask permission to do so ) only when you initiate a call.


The application screen is divided into two parts. A large part shows what the camera is focusing on.

At the bottom is a small section that shows the most recent contact, as well as buttons to create or group or invite non-Duo users to get the app.

Make the video call

First you need to have the application installed on your device, in case you do not have it, you must install it through the Play Store (Android) or the App Store (iOS).

Once installed on your device, you must complete the startup process, where you must complete some steps so that you can start using the application.

When you are inside the application you can use the ” Search bar ” at the top to find the person you are looking for. Or you can also swipe your finger over the bottom to open the full contact list.

Select on the name of a person and you will see the options to initiate a voice or video call. If you call someone and they don’t answer, you are offered the option to record an audio or video message instead.

For a group call, tap the ” create a group” button on the main screen of the application. You can add up to eight contacts to the group chat or call.


Only a few settings are available during a video call. It can be muted or switch to the rear camera of your mobile. Tapping the three vertical dots in the window opens additional options such as “Portrait” and “Low Light” mode .

The latter is especially useful if the lighting in the place where you are is not very good, and it allows to obtain a fairly bright and clear video.

Record audio and video messages

One great feature of the Duo that makes it stand out from the crowd is the ability to record and send video messages, and even add fun filters and effects.

Of course, you can also send audio messages, but in the application market you can find a great variety that allow you to do so.

The option to send one automatically offers if someone doesn’t answer your call, or you can just send a video message first.

Send audio and video messages

Touch a contact name and choose from the options to send an audio or video message, or a note. You can also attach images from your device’s photo gallery .

To record a message first, simply swipe your finger across the main screen to bring up the contacts available on your mobile. You can select up to eight contacts

Just tap the ” Record ” button at the bottom of the screen to get started. Press it again to finish and send the recording.
