Next time someone contacts you on Facebook Messenger for the first time, you'll see a calling card of sorts showing his photo, other public info and how you two are connected. Facebook's Vice President of Messaging, David Marcus, calls it "enhanced caller ID for messaging," and it shows up even if you're not Friends with the other person. It lists helpful clues to jog your memory in case you can't remember who's trying to contact you, including his job, school and if he lives in your location, which are the same pieces of information shown by Facebook's Hello caller ID app for Android. This "Messenger caller ID" feature, however, is rolling out to both iOS and Android devices, but only in the US, the UK, India and France for now. Hopefully, it can save you time from clicking through to a weirdo's profile and prevent you from dismissing important messages sent by potential employers or old friends.
