I have a complete set of test cases for my new Android app and now need ten fresh sets of eyes to run through them. Your role is to install the latest APK on real Android hardware, execute every assigned scenario, and look at the product from three angles: functional accuracy, overall usability, and basic performance (start-up time, scrolling smoothness, battery impact). Once you finish the entire suite, deliver: • The filled-in test-case spreadsheet I will provide • A consolidated bug list with steps to reproduce, screenshots or screen recordings, and device details • A brief usability summary covering navigation clarity, visual consistency, and any friction points • Noted performance observations (numbers or qualitative notes are fine) All feedback is expected in one drop after you complete the last test case; no daily status reports are necessary. If you have multiple Android devices, please mention them in your bid so I can spread coverage across OS versions and screen sizes.
