That is a terrible headline. You can't make FaceTime calls on anything but Apple devices. You can receive FaceTime calls but not make them. I can't believe this one through all the editors and they thought this headline was a good idea. Please change the title of this article to how to receive FaceTime calls on Android not make them.
You're right, of course. We're very sorry for getting this one wrong and have changed the title (and aspects of the body copy) accordingly. It was a genuine mistake, rather than an attempt to mislead people, but we'll strive to be better in future.
