Try the phone flashlight where browser control is supported, with a guided manual fallback.
Start flashlight control and observe the rear light. Turn it off after checking. If browser control is unavailable, use the flashlight control in phone settings.
The page cannot see whether the light physically turns on. An unsupported browser torch control is not proof of a defective flash.
Camera access may be requested for browser torch control. Avoid shining the light into anyone’s eyes.
