What to establish first
- 1
Check ChromeOS Settings → Privacy and security → Privacy controls for Camera/Microphone access.
- 2
Then check the site's Chrome permission.
- 3
If one web app fails but DeviceOK works, investigate that site's selected device/permission before hardware replacement.
Useful browser evidence on ChromeOS
Browser Permission CheckCheck whether common browser permissions such as camera, microphone, location, and notifications are granted, denied, or still waiting for a decision.
→Webcam TestOpen your webcam locally to verify that the browser can access and display a live camera stream.
→Microphone TestCheck whether your browser can detect your microphone and receive live audio.
→Keyboard TestPress keys and verify that the browser receives the expected keyboard events.
→Touchscreen TestDraw on the screen to verify touch/pointer coverage.
→What not to infer
- Linux-container apps can have separate permissions from ChromeOS browser apps.
- Browser tests cannot inspect internal storage/memory health or firmware directly.
- Managed school/work Chromebooks can have administrator policies.
