Postural assessment software (SAPO/PAS) were used to analyze and document postural findings, the smart phones addiction scale (SAS) used to assess the degree of addiction to the smart phones, the Quality of Life Index scale(QoLI) also used to assess the quality of life among students. Results: Screening showed that the most common postural deviations recorded were regarding the head, 87.9% of the sample presented some deviation in the horizontal alignment of the head from anterior view, 100% of the sample had forward head from lateral view. Regarding the shoulder, 87.1% of the sample had drop shoulder, 93.6% of the sample had drop pelvis. Regarding the trunk 97.1% of the sample had scoliosis, 31.4% had false leg length discrepancy .The results showed a strong relationship between smartphones addiction and decreasing the quality of life among the students, also there were a strong relationship between SAS and the postural deviations developed
