Why did FaceTime notify me?

I was FaceTiming my boyfriend and then during the end of the conversation before it cut off, it notified me saying his name and that he had taken a screenshot of our conversation

Why did it do this? Does iPhone FaceTime really notify people when they screenshot your face on FaceTime?

Yes. Maybe he took a screenshot for his contact list. I have not used it but that is my thoughts.

Yes, it does

Yes, it does
