It is convenient for middle school students to use mobile phones, but it also has shortcomings.

First of all, health is a common concern. Mobile phones have a certain impact on human health. When sleeping, many people put their mobile phones on pillows. The radiation of mobile phone will cause dysfunction of human central nervous system, causing headache, dizziness, insomnia, dreaminess, hair loss and other symptoms. Some people also have a sense of excitement on their faces.

Many people often play with their mobile phones after turning off the lights. The glare of mobile phones can cause macular degeneration, ranging from dry eyes to blindness. Secondly, many people suffer from "mobile phone dependence", which seriously delays their study and work.

Thirdly, students now have different grades of mobile phones, which is very easy to cause psychological imbalance, cause the wind of comparison, and cause economic burden to parents. Finally, mobile phones are valuables, which not only bring opportunities for criminals to steal, but also may cause some bad students to steal. It has seriously affected campus safety.
