Contact and feedback
Feedback from people testing unusual hardware is the main reason the diagnostics keep improving.
What is most useful to report
A controller that is detected but shows the wrong layout, an input that never registers here but works in games, a test that behaves oddly in a particular browser, or wording in any language that reads awkwardly.
Including the controller name shown in the status panel, your browser and version, your operating system, and whether the pad was connected by USB or Bluetooth makes an issue far quicker to reproduce.

Please do not attach a saved report unless you want to share it. Reports are generated on your device and are never uploaded automatically.
What cannot be answered here
Individual repair diagnosis, warranty claims and manufacturer support all belong with the controller's manufacturer or retailer. GamePadTestLab measures browser-visible behaviour and cannot assess hardware beyond that.
