The symptom
A dead motor is easy to miss. You only notice the calls you never felt arrive.

What is inside
Most phones spin an offset weight or drive a linear actuator to make the buzz.

Check this first
Silent mode, Do Not Disturb and per-app vibration all switch the buzz off.

Run the test
The browser asks the phone to vibrate in short, long and pulsed patterns.

Result: weak
A faint buzz often means a loose motor mount or a case damping the vibration.

Result: nothing
With settings ruled out, silence points at the motor or its connector.

Intermittent buzzing usually means a failing solder joint or a worn motor.

One honest limit
Safari on iOS does not support the browser vibration API, so use Android.
