Nomophobia is considered a disorder of the modern world. High levels of reliance on smartphones have led to the emergence of symptoms of nomophobia, which is a symptom of a type of phobia characterized by excessive fear when one cannot use a smartphone.

Another common denominator today is the increase in students' dependence on smartphones. The rapid development of smartphone technology by providing a variety of attractive features and easy communication has led to students being able to avoid relying on smartphones. The pattern of smartphone use among students has shown a disturbing indicator. Students have become addicted to smartphones, and the situation has affected student success academically. Smartphones have become a new social norm that is a moral reference. Smartphones have transformed the culture, public health, and technological status of today’s society.

This symptom of nomophobia can lead to social isolation. Social isolation is a process that shows that people with high segregation tend to behave in ways that are contrary to normal social norms. There is a relationship between the level of cell phone dependence and social isolation between users and many new teens. 

Nomophobia is increasing in such a way that it cannot be ignored, especially among young people. Along with previous studies, the relationship was found between levels of nomophobia and online addiction among high school students. Levels of nomophobia of high school students were found to be slightly above average. In terms of gender differences, female students have a higher tendency to exhibit nomophobia behaviors compared to male students. 

A sociologist says that the symptoms of social isolation are related to five factors. 

1. Powerlessness: 

Man feels isolated in society, and the situation is beyond his control, so he feels powerless to change his way of life. 

2. Meaninglessness: 

People who think that this life has no purpose. 

3. Social normlessness: 

The state of people who lose their ideas, goals, and values in their lives. 

4. Isolation: 

Individuals feel disconnected from shared values, beliefs, and practices, and have no meaningful social relationships with others. 

5. Self-estrangement:

Individuals experience social isolation and often avoid meeting the needs of others and social norms.

The problem of social isolation is a social phenomenon that occurs everywhere and causes a person to live with his or her own country. It is seen that this is the trend for students. Students can easily be seen using smartphones at every opportunity, even in teaching halls. Students use smartphones when the learning process takes place. Students are often told that they are no longer controlled by the power of information technology to become dependent and weak. 

People are being unsocial. They are moving away from social norms and day-to-day social relationships. They can even communicate through Social Networking Systems but not in real life. So, it's a scary story. We must reduce it otherwise social divisions will increase dramatically. 

However, early prevention efforts are needed in the face of social isolation. This effort can be made through community-based community learning leading to activities that have a strong obligation to meet in real community environments, so that students' dependence on the use of smartphones is reduced. This concept is based on efforts to improve community-based learning. The self-sufficient community can be seen as a simple social system
