I say this as someone who has been diagnosed with ADHD and who has a dad who says exactly the above, and who everyone in the family agrees almost certainly has undiagnosed ADHD.

I just think it’s important to not dismiss the very real effects of smartphone usage and addiction. If you struggle with ADHD symptoms, then it’s important to not dismiss and justify other factors that exacerbate them and make them even harder to deal with (especially when those factors are changeable, like reducing our social media and smartphone usage).
