Phone Vibration Test - TestMu AI (Formerly LambdaTest)

What is the Phone Vibration Test?

The Phone Vibration Test is a free online tool that checks whether your phone's vibration motor and haptic feedback are working. It uses the browser Vibration API to trigger a real vibration on your device, so you can confirm the motor responds without installing an app. Open it on your phone, pick a pattern, and tap Vibrate to feel the result instantly.

It is handy when notifications stop buzzing, after a screen or battery repair, or when buying a used phone. Because the test runs in your browser, there is nothing to download, and you can repeat it as often as you need to compare strength and timing.

How to test your phone's vibration?

Testing your vibration motor takes only a few seconds and works best on a phone. Follow these steps:

• Open the tool on your phone: Open this page in your phone's browser, ideally Chrome or Firefox on Android, since those support the Vibration API.
• Choose a vibration pattern: Pick a preset pattern or enter a custom one, and set the duration and repeat count you want to test.
• Tap Vibrate: Tap the Vibrate button and feel for the vibration. A working motor responds immediately with the pattern you selected.
• Stop or retry: Use Stop to cancel an ongoing pattern, then adjust the settings and test again to compare strength and timing.

Features of the Phone Vibration Test

As a tool, the Phone Vibration Test gives you quick, repeatable control over how your device vibrates. Here are the features of our tester:

• Preset Patterns: Try several ready-made vibration patterns to check short buzzes, long pulses, and rhythmic sequences.
• Custom Patterns: Enter your own sequence of vibration and pause durations to reproduce a specific notification feel.
• Duration and Repeat: Set how long each vibration lasts and how many times it repeats to test the motor under load.
• Instant Feedback: The vibration fires the moment you tap, so a healthy motor is easy to confirm right away.
• No App or Signup: Everything runs in the browser with no install, no login, and no usage limit.
• Browser-Based: The test uses your device's own Vibration API, so nothing is uploaded and no permissions beyond vibration are needed.

Browser and device support

Vibration depends on the browser supporting the web Vibration API, which varies by platform. Here is what to expect:

• Android Chrome and Firefox: Fully supported. The navigator.vibrate method triggers the motor reliably.
• iPhone and iOS Safari: Not supported. Apple does not expose the Vibration API to the browser, so the test cannot vibrate an iPhone from the web.
• Desktop Browsers: Most laptops and desktops have no vibration motor, so the test will not produce a physical response.
• Silent and Focus Modes: Some system settings suppress vibration, so check that vibration is enabled if nothing happens on a supported device.

Use cases of the Phone Vibration Test

Checking vibration is useful in more situations than you might expect. These are the most common:

• Troubleshooting Notifications: Confirm whether silent missed calls or messages are a motor fault or just a settings issue.
• After a Repair: Verify the vibration motor still works after a screen, battery, or board replacement.
• Buying a Used Phone: Quickly check the haptics of a second-hand device before you pay.
• QA and Device Testing: Validate haptic behavior across devices, and run the same kind of checks at scale on 10,000+ real devices and 3000+ browsers with the TestMu AI platform. Pair it with the User Agent and WebRTC Test tools for broader device checks.

This tool is maintained by TestMu AI (formerly LambdaTest), the team behind a unified testing platform, so it reflects the same focus on verifying real device behavior that QA engineers depend on. For a related network check, try What Is My ISP.

Frequently Asked Questions (FAQs)

How do I test my phone's vibration?

Open this page on your phone's browser, select a vibration pattern, adjust the duration if needed, and tap the Vibrate button. Your phone will vibrate if the motor is working correctly.

Why is my phone not vibrating?

If your phone does not vibrate, check that your device is not in silent mode with vibration disabled, that your browser supports the Vibration API (Chrome and Firefox on Android work best), and that the vibration motor is not physically damaged.

Which browsers support the Vibration API?

The Vibration API is supported in Chrome and Firefox on Android. It is not supported on iOS (Safari) due to Apple's restrictions. Desktop browsers also do not support vibration.

What are vibration patterns?

Vibration patterns are sequences of vibration and pause durations in milliseconds. For example, [200, 100, 200] means vibrate for 200ms, pause for 100ms, then vibrate for 200ms again. Our tool provides several preset patterns and also allows custom patterns.

Is the phone vibration test free to use?

Yes, the phone vibration test is completely free with no signup or limit. Run it as many times as you like to confirm your vibration motor and haptics work. The tool is maintained by TestMu AI (formerly LambdaTest).

Does the vibration test work on iPhone?

No. iOS Safari does not support the web Vibration API, so the test cannot trigger vibration on an iPhone from a browser. It works best in Chrome or Firefox on Android, where the API is fully supported.
