The modern smartphones attract teachers and students with their opportunities to develop competencies with numerous applications, and at the same time, the obvious and yet insufficiently studied threats associated with smartphones cause concern and concern. Having a huge potential for use in the educational environment, the phone becomes a cause of conflict, a hindrance in lessons and a competitor to productive pastime. The paucity and inconsistency of data on the impact of the phone on academic achievement, psychological well-being, and interpersonal relationships require further research. The study among junior students of the Institute considered the issues of productive and problematic use of mobile phones. The survey method was used to obtain information about the use of a mobile phone. One of the manifestations of the construct “problematic mobile phone use” is the presence of problems in various spheres of life, including problems related to school. As a result of the study, the positive and negative effects of mobile phones on educational activities were identified.
