What is Google Duo?

Google Duo is a mobile video chat app.

The History of Google Duo

Developed by Google. It was announced at Google’s developer conference on May 18, 2016, and began its worldwide release on August 16, 2016.



Share Your Phone’s Screen on Google Duo

On a video call, you can use Google Duo to share your phone's screen with others. The person on the other end of the line will be able to see your complete screen. If you allow screen sharing, your camera will switch off.


Use Google Duo From a Web Browser

One of the most useful advantages of Google Duo is that it can be used on a PC. You can make audio and video calls from your computer using Duo's web client.


Make Calls From the Dialer App

You don’t need to open Google Duo every time before calling someone. You can make video and audio calls to your contacts directly from your phone’s Dialer app.


Use Duo's Picture-in-Picture (PiP) Mode

With PiP mode, you can minimize your video calls to a smaller screen and use some other app simultaneously. This only works on Android smartphones running Android 8.0 or above, and iPhones running iOS 14 or above.


Make Use Of Duo's Data Saving Mode

Google Duo has a Data Saving mode, which is useful for people with metered data connections. It saves data by reducing the quality of video during video calls. By default, Google Duo makes HD video calls at 720p resolution.


Send Messages to Your Contacts

Like any other video calling app, Google Duo allows you to send messages to other people, but in a slightly different manner. You can send voice messages, photos, videos, and notes with text or doodles to your friends.
