I don't have time to review all the research that has been done on the topic, but fortunately others have done a review of the existing studies:
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9200624/ concludes "Despite the fears held around wireless technologies, we believe that at this stage there is not enough evidence supporting a causal negative relationship between MP/WD use and children and adolescent’s mental health to justify particular public health interventions."
And this isn't a review, but here's one additional study:
So I did a quick search through the scholarly literature and the consensus is overwhelmingly the opposite of your claim. So much so that I’ve decided not to link any studies (there are literally thousands). Science isn’t perfect and statistics alone guarantee many ambiguous results, some of which you seem to have found.
It would help if you could link to at least one of the thousands. What's one you think makes a strong case? I'm not sure if you're referring to actual studies or, maybe, confusing blog posts and "expert" opinions with actual studies.
