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.

→
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.

→
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.

→
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.

→
Speaker TestPlay a local test tone to verify audio output.

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

→
Device Orientation TestShow current portrait/landscape orientation and orientation changes.

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

Model-specific problems

Start with the symptom people actually search for

These paths combine this model's documented limits with live evidence, instead of copying a generic troubleshooting checklist.

iPhone 14 MagSafe charging is slowApple lists MagSafe up to 15W on iPhone 14, while ordinary Qi is up to 7.5W. Alignment, charger type, adapter power, heat and active use can all make real charging slower without indicating a battery fault.

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.
