Abstract: In order to solve the problem of students using mobile phones in class, 271 undergraduates from two universities in Anhui province were surveyed by questionnaire. SPSS was used to analyze the data of students' using habits, duration, purpose, learning influence and psychological self-evaluation of mobile phones in class.The results showed that there was little correlation between the use of mobile phones in class and the content in class. At the same time, students themselves can realize the negative effects of improper use of mobile phones in class and have a subjective desire to get rid of the habit. Therefore, it is necessary to take active measures to solve the problem of improper use of mobile phones in class.
