Screens/phones

I have a 14 yr old son who is doing well in school and trains 6 times a week in judo. I have a huge issue with the way he uses his phone and other screens.. but mainly his phone. I HATE toktok, I think it’s possibly the worst thing a teenager can use, and I hate the endless reels that promote cr@p and fry our brain. I’ve got parental controls and attempted to limit his time, but he overrides everything and I’m feeling pretty out of control of the whole thing now.

I’ve tried to encourage him to read, but he’s just not interested, he just wants to scroll on his phone or play whatever computer game his mates are playing.

Is this just his generation? Am I fighting a losing battle? What do you all do when it comes to screens?
