A picture is worth a thousand words! With video calling, you can see as well as hear the person you’re talking to on your mobile phone. You must have access to the Internet to use video calling. Your phone will use Wi-Fi when available, your cellular data connection if not, and switch between the two as needed.
If you are looking for a simple, easy-to-use video calling app that will work on iPhones and Android phones, look no further than Google Duo. Duo does one thing especially well: you can make high-quality, one-to-one calls to anyone else who has the app on their phone. You can’t make group calls or use Duo on a desktop.
A unique feature of Google Duo for Androids is Knock Knock—a feature that allows the receiver of the call to see a live picture of the caller before answering. If you are doing the calling, the other person can see what you are doing at that moment.
Google says that Knock Knock gets you smiling before the call starts, provided you are happy to hear from the person calling you! As a precaution, you can only receive Knock Knocks from people in your contact list, or you can disable it through Settings.
Google Duo is probably pre-installed on your Android. If not, you can find it in the Play Store. The setup is simple.
You can leave a video message if the person you call on Duo doesn’t answer!
