The way Android users complain about the lack of Apple iMessage and Apple FaceTime on their phones, you'd be forgiven for questioning whether Android had any messaging or video calling features.
I will tell you a secret: it's not Android users who complain about the lack of iMessage or Facetime. Most of them are not even aware of their existence. They are using Whataspp, or Viber, or whatever and go on with their lives.
