Functional testing of a mobile app on different devices

Before the next release we need a thorough functional check of our mobile application on a range of real devices, not just one modern phone. Our users span old and new hardware, small and large screens, and both platforms, and we keep hearing about problems we cannot reproduce on our own handsets. We are looking for a QA specialist who will build a set of test scenarios covering the main flows, run them methodically, and tell us honestly where the app breaks.

The work includes writing clear, reproducible bug reports with steps, expected and actual results, device and version details, and a screenshot or short screen recording. We want severity marked sensibly so we fix the right things first. After we deliver fixes, we need a regression pass to confirm nothing new broke and that the reported issues are truly closed. Coverage of registration, the cart and checkout, notifications and offline behavior is the priority.

Please tell us which devices and emulators you have access to, how you organize a test run, and how you report progress. We are not asking for automation on this task, though a note on what would be worth automating later is welcome. Clear communication and a calm, systematic approach matter more to us than speed.
