Vibration Test

We will trigger a triple haptic vibration burst. Verify if your hardware responded.

How to Use This Test

Click the Trigger Button

Tap 'Trigger Vibration Burst' to activate the device's vibration motor. A triple pulse pattern will be sent to the haptic hardware.

Feel for Haptic Feedback

Hold your device and feel for three distinct vibration pulses. The vibration should be clearly noticeable through the device body.

Rate Your Experience

If you felt clear haptic feedback, tap 'Felt Haptics' to pass. If the device didn't vibrate or the response was extremely weak, select 'No Response'.

What Your Results Mean

✓

Felt Haptics

The device responded with clear triple vibration pulses. The vibration motor and haptic feedback system are functioning correctly.

✗

No Response

The device did not vibrate at all, or the vibration was too weak to feel. This may indicate a failed vibration motor or API incompatibility.

●

Vibration Feels Weak

Weak vibration can be caused by a worn motor, thick phone case, or the phone resting on a soft surface. Try removing the case and testing on a hard surface.

●

Button is Greyed Out

The Vibration API is not supported on this device or browser. iPhones, iPads, and desktop computers typically don't have vibration hardware.

Common Problems and Fixes

Vibration button is disabled or greyed out

Your device or browser doesn't support the Vibration API. This is normal for iPhones, iPads, and desktop computers. The test only works on Android devices and other platforms with vibration hardware.

Button works but no vibration is felt

Ensure the phone isn't in silent/do-not-disturb mode, which may suppress vibrations on some devices. Remove thick cases and place the phone on a hard surface. If vibration still doesn't work, the motor may have failed.

Vibration is much weaker than expected

Vibration motors can weaken over time, especially after heavy use. A worn motor may still vibrate but with reduced intensity. This is a sign the motor may need professional replacement.

Phone vibrates but no pattern is felt

Some devices have very fast vibration motors that make it hard to distinguish individual pulses. The triple-pulse pattern may feel like a single continuous vibration on certain hardware.

Vibration works in some apps but not this test

Different apps may use different vibration APIs or patterns. The browser's Vibration API implementation may differ from native app vibration. Try a native vibration test app for comparison.

Frequently Asked Questions

Why doesn't the vibration work on my computer?

The Vibration API is only supported on devices with a vibration motor, primarily Android phones and tablets. Desktop and laptops computers, iPhones, and iPads do not support the Vibration API. The test will show a warning message on unsupported devices.

What is a triple vibration burst?

The test triggers three short vibration pulses in quick succession (200ms vibration, 100ms pause, 200ms vibration). This pattern is easily distinguishable and helps confirm the vibration motor responds to programmatic commands.

Can this test damage my vibration motor?

No. The test uses brief, low-intensity vibration patterns that are well within the motor's operating specifications. The Vibration API is commonly used by games and notifications without causing hardware damage.

My phone vibrates but it feels weak. Is that normal?

Vibration intensity can feel different depending on the phone case, surface the phone is resting on, and the motor's condition. A phone resting on a soft surface like a bed will feel weaker than one on a hard desk. If vibration is significantly weaker than when the phone was new, the motor may be wearing out.

Does this test work through phone cases?

Yes, the vibration motor's haptic feedback passes through phone cases. However, thick or rugged cases may dampen the felt vibration. For the most accurate assessment, remove the case before testing.

What does it mean if the button is greyed out?

A greyed-out or disabled button indicates the Vibration API is not supported on your device or browser. This is common on iPhones, iPads, and desktop computers which lack vibration hardware.
