In June of 2007, Steve Jobs introduced the first IPhone to the world, and it was truly revolutionary. Actually, it was not the first smart phone, but it had a touchscreen display that allowed users to perform daily tasks in almost all areas of life. (1) . It is no surprise that students love using their smartphones in and out of the classroom to text friends, call family, play video games or watch movies. Inside of the classroom, smartphones have a great deal of potential because of their almost limitless functionality. Students can use them for research, interactive games, video recording and class communication. In addition, smart phones offer access to information via the internet for low-income households who cannot afford computers (Maguth 88). (2). .

Smartphones should be banned from school because they cause harmful side effects from cell phone addiction. According to a study by Gaby Badre, in such cases, teenagers tend to experience increased restlessness with more careless lifestyles, more consumption of stimulating beverages, difficulty in falling asleep and disruptive sleep, and more susceptibility to stress and fatigue (Teen Ink). (3) . In fact, cell phone use late at night keeps students awake. The brightness of the screen stimulates their brain and makes their body feel like it is daylight. Furthermore, this evidence suggests that there are many health disadvantages to increase cell phone use among teens and adults. While there are many health disadvantages to teen cell phone use, there are also disadvantages related to school performance. (4) . The schools which banned cell phones showed in an increase in test scores by 6.4% for 16 years old students (Richard et Beland). Therefore, these results provide strong evidence in favor of banning cell phones in school because they show an improvement in test scores which is correlated to a cell phone ban.

For instance, there are many useful tools like Kahoot, Poll Everywhere and Twitter, which allow students to interact and exchange information quickly in class. While these tools are engaging and fun, they do not outweigh the harmful effects on students sleep, ability to focus and academic performance. On a separate note, it is true than smartphones offer a low cost option for internet access, which benefits low-income families the most. .(7) . Besides, most public schools have computer labs with high-speed internet, and all students can use them free under the supervision of teachers. Low-income students do not need to have a smartphone on them at all times during the day especially when their teachers are lecturing. What Maguth and pro-cell phone advocates fail to understand is that these technologies are having a profound impact on all of us. Numerous studies show that millennials in particular have a difficult time focusing on one task for long periods. In short, the internet and mobile technology is physically changing our brains.

In addition, using cell phones in schools negatively affects performance; in schools where the use of cell phones has been banned, students performance increased significantly especially with struggling students. These reasons definitely speak in favor of prohibiting teenagers using cell phones in high schools. School administrators need to look at the facts and make a truly smart decision. ..(9) .

However, just because smart phones are banned from the classroom, does not mean that low-income students cannot own them and use them outside of class, Many people have argued that cell phones have a useful place in the classroom claiming that cell phones can be used for a wide range of in class activities and provide socio-economic opportunities to low-income households through affo In the developed world, smartphones have now overtaken the usage of earlier mobile systems. For instance, according to British research of cell phone policies of Birmingham, London, Leicester and Manchester school effects on students performance have been discovered.
