Use the tools for a quick first check, then repeat in another browser or device when you need to isolate a problem.
Browser testing can show whether input events arrive and provide useful timing observations. It can help narrow down a problem, but it cannot inspect firmware, internal switches, radio conditions, or USB hardware directly.
Follow these steps to make browser observations easier to compare.

The tools report events and timing observed by your browser. Results can vary with the browser, operating system, display refresh, background load, and device connection, so they are not laboratory measurements.
Treat a result as a troubleshooting observation, not proof of a hardware defect. Repeat the test and use the manufacturer's diagnostic or support process when a formal assessment is needed.
