I need a quick round of functional testing focused solely on the user login and registration flow of my Android app. You’ll receive the current APK and any required test accounts. Scope: • Install the APK on at least one real Android device (emulator acceptable as a secondary check). • Work through every possible login and sign-up path—email, social, or phone (whichever are present). • Note any crashes, validation errors, or UI glitches, and confirm expected success messages and redirects. • Provide a brief test report with reproducible steps, screenshots or screen recordings of any issues, and clear recommendations. A concise turnaround and attention to detail are more important than elaborate documentation.
