> Do other countries not have teenagers addicted to smartphones?
I don't know where utility stops and addiction starts (since smartphones are also useful, merely spending a lot of hours on them does not constitute an addiction), but I don't know of anyone that might be smartphone addicted, nor is it a topic in the media (though I don't follow mainstream media that closely). I'm sure some must exist in western Europe as well, but I don't know that we have special programs for them.
