In the
ranking of the most connected countries, by 2018, South Korea occupies a modest 16th place with 40.1 million users, but after all, the country's population is now less than 50 million people, that is, 80% are already online. This is largely due to the extremely
prolific Samsung and slightly less prolific LG Electronics, as well as high-quality, high-speed 4G Internet.
Back in 2011, Korean psychiatrist Sam-Wook Choi, specializing in working with addictions (alcoholism, drug addiction, gambling), discovered a new ailment: dependence on smartphones.

In the US, physicians are skeptical of technological dependencies. Neither Internet addiction nor “smartphone” drug addiction is described in the manual of mental disorders. Is that gambling in them. Choi and his colleagues point out that if Internet addiction implies most often online games, then dependence on smartphones is a constant use of social networks.
Korea was probably the first to reach this ailment. As it was written above, Samsung, LG and LTE did everything possible for this. 80% of the population use smartphones, in the USA this figure is 70%. The average South Korean spends 4 hours a day staring at a smartphone. Interestingly, online games are preferred by men, and pathological craving for smartphones is inherent in the beautiful half of the Korean population.
What is the dependence? People use the smartphone in a different way. 22% longer, but the main difference is in the ways. These people often sit on social networks, trying to get rid of stress, depression and boredom. Most often from six in the evening until midnight. They read, watch pictures and get distracted by alerts from mobile messengers and social networking apps.
To diagnose addiction, Korean professors Heejune Ahn and Uichin Lee
developed Android applications and tested it on living people. As a result, it showed efficiency of 87% - with such accuracy, the algorithm identified dependent people. But for some reason they could not cure such applications - people did not change their habits.
About the new disease we still have to learn. So far, only one thing is clear - many without smartphones simply
cannot live .
