What are the social costs of cell phone usage?

The social costs of cellphone usage can be defined as a depreciation of social interactions.

Explanation:

Cellphones were invented in 1973 by Martin Cooper and they were designed with the purpose of offering a mobile way to communicate with others erasing the limitations that phones offered at that time.

However, today we are facing an era in which cellphones have gone way beyond the point of being just a portable device for phone calls. Social networks, cellphone gaming, chats, photographs, and all kind of apps with different services are just a glimpse of what cellphones offer now, making society somehow dependent on the device itself. Which unfortunately has led to less use of face to face communication, building some sort of barriers  in which emotions and true meaning are easily disguised because is safer to simply express ourselves behind a cellphone, that is why society face bigger issues related to bullying and cyber bullying. People no longer truly know each other, simply replacing emotions  with emojis and ideas with memes leading us to no longer understanding each other and what is worse, not caring about it.
