摘要：The objective of this research was to analyze the factors related to the satisfaction of using smartphones with the Android, iOS and Windows Phone operating systems. The target audience was undergraduates and graduates in courses in the areas of Engineering, Computing and Administration. The database was created through the application of an online questionnaire, based on the Questionnaire for User Interaction Satisfaction - QUIS version 7.0. The interviewees expressed their comfort and acceptability of such systems through grades between 1 and 9 points. The evaluated items were: screen, terminology, learning and system capabilities. A multivariate analysis of the data was applied to obtain the results. The factor analysis and dimensionality reduction by principal component matrix pointed out four new factors that explain 69.2% of the variance of the 21 features initially studied. Issues related to system error messages were the variables with the highest correlation (0.884 and 0.889). The results of this research serve as a guide to new evaluations of operating systems and support for analysis and improvement of usage satisfaction over mobile applications. As recommendations, it is suggested to include new groups of respondents, understanding that factors may interfere or not in the final satisfaction of the users of these platforms.
