Google Duo apk

Google Duo - High Quality Video Calls apk is a mobile video chat application developed by Google, available on Android and iOS operating systems. It is also available for use via Google's Chrome browser on desktop and laptop computers. Google Duo allows users to make video calls in high resolution. Google Duo is based on phone numbers, allowing users to call someone from their contact list. Users can leave messages up to 30 seconds long for contacts not available. Support for eight-person video calls in both the iOS and Android versions of the app was added in May 2019. Along with similar group calling services from FaceTime, WhatsApp, Skype and Facebook Messenger, attendees Joiners can join or leave the conversation at any time.

Features of Google Duo apk

The Knock Knock feature allows you to preview live video displayed for up to 30 seconds before you receive a call or disconnect. If you are starting a call, you will see a small message saying your video is visible, meaning that others can see what you are doing right at the moment during this time. Android users can easily find Knock Knock at any time whether Duo is open or not (as on the lock screen).


Knock Knock is enabled by default, so if you don't want to see anything on the other end of the line, you can turn this off. You can block each person (in the Duo Setup menu), this way, when you block a person on Duo, they themselves will not know it. When calling, they only hear the line bell on your phone is constantly pouring only. Knock Knock feature does not appear on devices running iOS because Apple does not allow tampering with the lock screen.

Super-simple interface: Duo has a very simple and intuitive interface. Before starting a call, you'll see an icon to start your recent video calls and contacts (voice call options are not supported yet). During a call, you'll see yourself (in a small circle), and icons to turn off the sound, switch the camera, and turn off the call. Live video from the other end of the line will display your mobile screen.

You can send messages in group chats with up to 150 people or video calls with up to 10 people.

The advantage of Google Duo over other applications is that it does not force users to sign in to a Google account to make calls. It means that just by installing the Google Duo application, people can make video calls to each other via the mobile number in their phonebook.

Video call quality: Like other video calling apps, the quality of Google Duo calls depends on the internet you are using (Wifi or mobile network). If the transmission line is strong, the live video will have clear sound quality and the displayed image is more detailed, not blurry.

In addition, Google Duo also has the feature to automatically switch the connection between the mobile network and Wifi when detecting weak waves, slow networks, so that users do not drop calls.
