I count my blessings with my girlfriend that hardly ever uses her smartphone and doesnt use Social media (family facebook aside which she looks on once a week or so). I guess we both were born just early enough to not have to grow up with this and not really being that invested in it.
My brother on the other hand, who is younger than me and finding himself more in the generation that over-uses their Phone and social media, was not so Lucky. Not just once, but three times now he dumped a girlfriend because she was constantly making selfies, pictures of their dinner (and breakfast/lunch) and on Whats-App every chance she got.
How much would you be bothered with these things? Enough to dump your partner?
