If you make video calls on your Android device, then you're probably familiar with Duo, Google's app that was designed exactly for that (basically a Hangouts replacement). But it's struggled to overcome the network effects advantage of apps such as WhatsApp and Hangouts: No matter how good Google Duo is, when all of your friends and family member use a platform, it's hard to get them to switch. However, these will be audio calls and the recipient has the liberty to accept, hang up, change cameras or mute their mic.
Reports suggest that users, who have installed the latest Android version on their smartphone, can access Google Duo without downloading the app. Well, one of the best features on Google Duo named "knock knock" comes to the rescue.
And in case a user hits a button to navigate away while the Duo call is connected, similar to how a full-fledged app functionality would allow you, it will show you a persistent notification icon that can bring the call back into view, at any point.
Obviously Google would prefer it if every Android user chose to roll with Duo for their video messaging needs. At the end of the call, the person will be prompted to install the Duo app if interested. It also provides an option to block future calls from the user so as to provide more privacy and not to allow anyone to keep making calls without your permission.
What are your thoughts on this new-found feature on Google Duo?
Google said it'd make App Preview Messaging available to all developers after an initial preview program, but that's yet to happen.
