Why doesn't vibration work?
1. Your device does not support vibration in the browser
Not all phones or browsers support vibration via JavaScript. Older devices or restricted operating systems may lack support entirely.
2. Silent mode or “Do Not Disturb” is enabled
If your phone is in silent mode, Do Not Disturb, or focus mode, vibration is often blocked. Turn these off and try again.
3. You must interact with the page first
Most browsers only allow vibration after a user interaction—like clicking a button. Automatic vibration without a click won’t work.
4. You may be using an unsupported browser
Vibration works in:
- ✔️ Chrome (Android)
- ✔️ Firefox (Android)
- 🚫 Safari (iPhone) does not support vibration on websites
5. You're using a computer
Desktops and laptops don’t have vibration hardware, so it only works on supported phones and tablets.
