It may well be the thing that is causing them to do so.
I'm not sure I got what you're saying. Are you saying that "smartphones and social media" may be what is causing them to identify as non-binary?
Is that not a possibility? In terms of public identification, my answer is, yes, definitely. In terms of private identification, my answer is also yes, but I appreciate that many people think this is a manifestly positive outcome. In which case, it is up to the individual to parse the perceived harms of social media use from the perceived benefits benefits and the desired outcomes from the undesirable.
