A study on smart phone addiction among adolescents has found that one in every four kid has a 'very problematic relationship with their phone.' Conducted by researchers at King’s College London, the obsession with phone was shown to be similar to typical addiction symptoms panicking or getting upset when their phone was unavailable, difficulty in controlling the amount of time spent on the phone and preferring their phone over other enjoyable activities. The researchers accessed 41 different studies linking mental health and smart phone addiction since the year 2011, analysing almost 42,000 young adults.
