Mobile Device Usability Testing: A Contrast of Various Operating Systems

This paper describes a study that compares the results of mobile app usability testing in various environments. The comparison includes two of the most popular platforms among users, Apple's iOS and Google's with five of the eligible participants. Google Drive is the name of the app that was developed for the Google Android platform on the Samsung Galaxy S10 smartphone and the Apple iOS platform on the iPhone Pro 11. Participants were given a scenario to complete. The scenario is broken down into three tasks that have to be completed in a specific order which is: Increase the capacity, Move, and Search. Each task's performance was evaluated using specific criteria, i.e., time taken to complete the task, total mistakes in the task, and time taken to correct a mistake. To collect user feedback, suggestions, and notes, the System Usability Scale (SUS) questionnaire was used. According to the findings of the empirical study and the evaluation review, there were no significant usability issues in terms of efficiency on either platform. There was a discrepancy in the implementation of tasks in a task for the benefit of one of the systems and in another task for the benefit of the other system. Taking all of these disparities and results into account, as well as what was revealed by a more comprehensive analysis of the SUS survey responses, we come to the conclusion that the iOS model outperformed the Android platform.
