Test matrix

What to test and what a pass actually tells you

Run the test closest to the symptom. A passing result narrows the diagnosis; it does not certify the entire device.

Touchscreen TestDraw on the screen to verify touch/pointer coverage.

Use the result to narrow the next branch; browser visibility is intentionally limited to the subsystem exposed by the current API.

→
Multi-Touch TestTrack multiple simultaneous touch points.

Use the result to narrow the next branch; browser visibility is intentionally limited to the subsystem exposed by the current API.

→
Touchscreen Dead Zone TestUse a grid overlay to inspect areas that do not respond to touch.

Use the result to narrow the next branch; browser visibility is intentionally limited to the subsystem exposed by the current API.

→
Screen Resolution TestShow browser viewport, screen dimensions, and device pixel ratio.

Use the result as a visual/timing reference. It cannot certify panel electronics or cable signal integrity by itself.

→
Dead Pixel TestShow solid colors full-screen so you can visually inspect for dead or stuck pixels.

Use the result as a visual/timing reference. It cannot certify panel electronics or cable signal integrity by itself.

→
Microphone TestCheck whether your browser can detect your microphone and receive live audio.

A pass proves the selected input delivered audio into this browser session; app routing or processing becomes the next branch.

→
Webcam TestOpen your webcam locally to verify that the browser can access and display a live camera stream.

A pass proves this browser received live camera frames; app selection, permissions or capture mode become more important if one app still fails.

→
Left Right Speaker TestPlay left and right channel tones separately.

A pass proves browser playback reaches the selected output path; it does not prove every codec, surround or app-specific route.

→
Charger Wattage MatchCompare a device's entered power requirement with a charger's rated wattage while keeping USB-PD/PPS and voltage-profile limits explicit.

Use the result to narrow the next branch; browser visibility is intentionally limited to the subsystem exposed by the current API.

Evidence handoff

If the browser cannot reach the suspected subsystem

Keep the browser result as one observation, then move to the operating system or manufacturer diagnostic that can see the protected hardware state. Do not interpret an unsupported browser API as a failed component.
