Hardware Context: The HTML5 Vibration API directly controls Android vibration motors. Weak or rattling vibration indicates disconnected springs or a loose linear motor bracket inside the phone housing.

Frequently Asked Questions

What is the difference between ERM and LRA vibration motors?

Eccentric Rotating Mass (ERM) motors use a spinning off-balance weight, producing coarse vibration with noticeable ramp-up latency. Linear Resonant Actuators (LRA) and haptic feedback motors use magnetic springs for instant, crisp tactile clicks.

Why does the Navigator Vibration API not work on iOS devices?

Apple iOS Safari intentionally does not expose the W3C Vibration API for web applications. The API is fully supported on Android Chrome, Edge, Firefox, and Opera.

Can vibration tests help diagnose physical hardware loose screws?

Yes. Continuous vibration pulses will induce audible metallic rattles or chassis buzzing if internal motherboard shield screws or battery tape have worked loose.
