What is the Knock Knock Feature of Google Duo

It's not the knock-knock, who's there- joke you're thinking. It's a feature of Google Duo that lets you see the preview before you answer them. It's quite intriguing what it looks like when you're waiting for someone to answer the call- if it's someone excited to talk to you or you'll know from their facial expression that it would be a good or a bad call. Learn more about the Knock Knock feature below. 

Knock Knock feature

Google Duo's knock-knock feature lets you see the preview of your caller before you answer a call. After 30 seconds, the preview will disappear and will disconnect after. It is a feature where only your contacts are allowed to do this. But if this is not your type of notification, you can turn it off in a few easy steps. 

Turn on/off your knock-knock feature:

On your phone, open the [ Meet] application > [Menu] icon > [Settings] > [Calling Settings] > [In-call settings] >  [Knock Knock for this device], and toggle to turn on/ off.

Note: Once you update Google Duo to its latest version, its name and icon change to Meet.
