This study aims to discover whether there is a significant difference in preservice classroom teachers’ levels of problematic smartphone use by gender, whether they use information and communication tools consciously, and duration of daily smartphone use for internet, social media and for purposes other than phone call. The study was performed at Abant İzzet Baysal University in the academic year of 2015-2016. 294 students (72 males and 221 females) participated in the study. The personal information form and the Smartphone Addiction Scale-Short Form was used for collecting the data. The Mann Whitney-U and Kruskal-Wallis tests, which are nonparametric techniques, were used for two-category variables and multi-category variables respectively. The Mann Whitney-U test was utilized once again to find out by which groups the intergroup difference was caused. It was discovered in the analyses that the female students, those who stated they do not use smartphones consciously and those who stated they need education about conscious use had higher levels of problematic smartphone use than the male students, those who stated they use smartphones consciously and those who stated they do not need education about conscious use. Furthermore, it was observed that levels of problematic smartphone use increased as the duration of daily social media, internet and smartphone uses extended. The findings were discussed within the scope of the literature related to problematic smartphone use
