I need an experienced mobile-app QA specialist to run a full, end-to-end test cycle on our live application for both Android and iOS. Functional accuracy is my top priority, yet I still expect you to keep a close eye on UI/UX polish and overall performance. You will work with a very wide device matrix: more than 100 Android handsets across Vivo, Oppo, Samsung and other brands—covering low, mid, and flagship tiers plus the usual range of screen sizes. On iOS, please cover every build from iPhone 11 onward, including the latest release. Critical flows such as login & registration, payment processing, and in-app navigation must be exercised thoroughly along with the rest of the feature set, so treat the assignment as a full regression sweep rather than a spot check. Deliverables I expect • A structured bug report for every build tested that clearly lists the device name, exact OS version, and reproducible steps for each issue. • High-quality screenshots or screen recordings attached to every defect. • A consolidated test summary highlighting pass/fail rates, critical blockers, and any performance or UX observations that could impact users. Kindly attach a detailed project proposal that outlines your testing approach, sample reporting format, and the real devices you have on hand; generic résumés alone will not be enough. Only seasoned mobile testers with a proven track record should apply.
