Live test
Ready.
What it measures
Checks support for permissions, media devices, Gamepad, Web Audio, Clipboard, Web Share, Fullscreen and other browser capabilities.
How to interpret problems
A missing capability can be browser/version/platform policy rather than a device fault.
Diagnostic workflow
- Run the test twice in this browser.
- Repeat in another browser when possible.
- Reconnect or re-pair the device and repeat.
- Compare another USB port, cable, output/input selection or device.
- Only treat the result as a hardware fault when the behavior remains consistent across environments.
FAQ
Does this install anything?
No. The diagnostic runs with browser APIs. Device-permission tests ask the browser for permission only when you start them.
Does NovaTools upload my device input?
These Test Lab modules are designed to run locally in the page. Camera and microphone previews are processed in the browser and are not sent to a NovaTools processing endpoint.
Can one failed result prove the hardware is broken?
Not always. Browser, operating-system, permission, driver, cable, wireless and power settings can produce similar symptoms. Use the troubleshooting guidance and compare another environment before replacing hardware.
