The updated version of Facebook Messenger implements the new Chat Heads feature, allowing you to see a small round icon with the face of the person you’re talking to hovering on the display even when you exit the app. When engaged in a conversation in Messenger, exiting the app will automatically create a chat head floating on top no matter where you navigate, allowing you to quickly jump back into the conversation. The chat heads can be arranged freely and dismissed at any time by dragging them off the bottom of the screen.
