Phone Vibration Motor Test
Test your phone's vibration motor right in the browser. Trigger short, long, double and SOS haptic patterns to confirm the motor works. Everything runs locally on your device and nothing is uploaded.
Tap a pattern to buzz the device motor. The page must be visible for vibration to work. iOS Safari does not support this API.
100% local — nothing leaves your device
How to use it
- 1 Open this page in a supported mobile browser such as Chrome on Android.
- 2 Tap a pattern button: short, long, double or SOS.
- 3 Hold the phone to feel each buzz and confirm the motor responds.
- 4 Try other patterns to check for weak, uneven or missing vibration.
Troubleshooting
Vibration test does nothing on iPhone in Safari
iOS Safari does not support the Vibration API, so web-based haptic tests cannot trigger an iPhone's Taptic Engine. This is an Apple limitation, not a fault with your phone. To test an iPhone, use the built-in vibration in a system sound or alert setting instead of a browser tool.
No vibration in Chrome on Android
First check that Vibration is enabled in your phone's Sound and vibration settings and that Do Not Disturb or silent mode is not blocking it. Make sure the tab is in focus and visible, since browsers ignore vibration on background tabs. If it still fails, the motor may be faulty.
Vibration feels weak or uneven on Windows 11
On Windows 11 desktop browsers most devices have no vibration motor, so the test silently does nothing. Vibration is designed for phones and tablets with a haptic motor. Run the test on a supported mobile browser like Android Chrome to feel weak or uneven buzzing from the motor itself.
Button does nothing and no buzz at all
Your browser may not support the Vibration API. Confirm you are on a mobile browser like Android Chrome, then check that the phone is not in silent or vibrate-off mode. Some manufacturers disable haptics for web pages, so test the motor through the system settings if needed.
Frequently asked questions
Does my phone vibrate correctly?
Tap each pattern button. If you feel a clear buzz for short, long, double and SOS, the vibration motor is working. Missing, weak or uneven buzzing can indicate a hardware fault or a system setting blocking haptics.
Why doesn't the vibration test work on iPhone?
iOS Safari does not implement the Web Vibration API, so no browser can trigger an iPhone's Taptic Engine. This is an Apple restriction. Web vibration tests work mainly on Android Chrome and other supported mobile browsers.
Do I need to grant any permission?
No. The Vibration API requires no permission prompt. Just tap a button and the phone vibrates immediately on supported browsers, as long as the page is in focus and the device is not in silent mode.
Is anything uploaded or sent to a server?
No. The test runs entirely in your browser and triggers the motor locally on your device. Nothing about your phone or its vibration is uploaded, stored or shared. It is 100% local.
Which devices and browsers support this haptic test?
It works on mobile browsers that support the Web Vibration API, such as Chrome and most Chromium browsers on Android. iOS Safari and most desktop browsers without a vibration motor are not supported.
