I know a family with teenagers that helped this by only allowing each kid a phone without social media at first, when the kid was in eighth grade or so. And after a year they could use social media on the phone. Also, after a certain time every night they insisted everyone in the family put their phones at the charging station in the kitchen. So at least no late night social media. So they had phones they just couldn't use them for social media purposes nearly as much and not until a later age.

This would take discipline but it did seem like their kids were less phone dependent and social when I've talked to them.
