You cannot use the FaceTime app directly on Android
Ask an iPhone, iPad, or Mac user to create a FaceTime link
Open the FaceTime link in Chrome or another supported browser on your Android device
Enter your name
Tap Join
Wait for the call host to admit you
Use your microphone and camera controls in the browser during the call
Leave the call when finished
If the link does not open, update your browser and try again
If the camera or microphone does not work, allow browser permissions for both
If the call quality is poor, switch to a stronger Wi-Fi or mobile data connection
