However, due to dearth of studies on personality types and smart phone addiction among students in the Nigerian environment, this study investigated the relationship between personality types, smart phone addiction and specific phone usages among University students. A sample size of 200 was used for this study using systematic sampling technique in the selection of respondents in the study area. Findings revealed that conscientiousness and agreeableness personality types had significant positive correlation with smart phone addiction; while extraversion and neuroticism had significant negative correlation with smart phone addiction.
