I asked a friend who doesn't use a smartphone about how it feels walking into a room full of people with phones and he told me the same thing. I have a smartphone but I don't take it out reflexively. I don't even consider myself a very social person or an extrovert, yet it always has to be ME to start a conversation in a room full of people because they would rather stare at a screen that say a hello.
I'm going to talk to you whether you like it not. If you don't want to talk to people, then maybe don't put yourself in a social setting? Imagine entering a coffee shop and finding it dead silent. I would just go home and make some food. If you have a problem with me talking to you, go ahead tell me how much you don't appreciate it or whatever, I don't care.
