Google Duo is by far the best video call platform for Android users. Google owns Android, so it works flawlessly with their software. For some phones, Google Duo is already pre installed. Google says that it is "dedicated to improving people's lives."
First, you need to download Google Duo to your phone. Download it from the Google Play Store or the App Store by searching "Google Duo."
Second, launch the app. Give Google Duo access and permission to use your phone's camera and microphone.
Third, verify your phone number with Google Duo.
That is it. There is nothing left that you need to do.
Just wait for your teacher to call you. When they do, make sure that your camera and audio are on so that your teacher can teach you.
You've got this! Everyone Great has a Beginning.
