What this test checks
How to use this test
Press a pattern button while holding the device safely; each request stops automatically.
What the results mean
A felt pulse confirms that this browser accepted and performed the request on this device.
Troubleshooting
Try the device’s main browser, exit battery-saving mode, and confirm vibration is enabled in system settings.
Browser limitation
No vibration can mean unsupported browser policy, silent platform behavior, or hardware—not necessarily failure.
