LIKELY CAUSES

Site permission is not granted.
Another app may own the camera or the selected mode is unavailable.

ACTIONS

Allow camera access and close call or capture applications.
Retry the default resolution before selecting a high-resolution profile.

RETEST CONDITION

The live preview and negotiated settings must appear.

Actions are generated from visible Evidence fields and versioned product rules. They do not identify a physical root cause with laboratory certainty.

Optional. The test works without this; these tips only reduce comparison noise.

MEASUREMENT BOUNDARY

Useful evidence, without pretending to be a laboratory.

Settings describe the browser stream, not every sensor mode.

Focus and image quality need visual inspection.

Local stills clear when the tab closes.
