Best documentaries on smartphone/internet addiction?

[Ray]

Hey guys, 

 

I was looking for great documentaries that tackles the topic of smart phone/internet addiction; so that explain which are the problems that arises for staying a lot of time in front of a phone or a pc. Something that even speak about the neurological effects, such as the release of such and such chemical while we are on the internet that wouldn’t be natural and in the long run is harmful. Let me know, thanks :))
