When users interact with smart phones, the  issue of fluency can influence their experience. However, there has been no previous clear definition and structure of smart phone fluency. The objective of this study is to confirm the factors influencing smart phone fluency and identify operational problems that affect smart phone fluency. A large-scale questionnaire survey was conducted, and 637 questionnaires were collected. We found that fluency is the most important feature of an easy-to-use smart phone. Moreover, the results confirmed the six factors of smart phone fluency: response delay, simplicity, operation error rate, connection, hardware, and visual experience. We also found that there were significant differences in the importance evaluation of visual experience and operation error rate among different age groups. In addition, opening the application, using the application, and opening the browser were the three operations in which people had the least fluent experiences. This study successfully confirmed the elements of smart phone fluency and contributed substantially to future smart phone design to shape a better user experience.
