Vibration tester

Triggers the phone's vibration motor so you can check that haptics work and how strong they feel. Useful when notifications stop being felt.

How it works

The mechanism, not the marketing.

The tool drives the haptic actuator directly. If it responds here but notifications are not felt, the problem is in settings or a per-app configuration rather than the hardware.

Phones use different actuators. Older devices use a small offset motor, while newer ones use a linear resonant actuator that produces a sharper, more precise tap.

Honest limits

What a phone cannot do here.

  • This drives the motor; it does not measure vibration. To measure external vibration, use the accelerometer readout or record it with the logger.
  • Perceived strength varies with what the phone is resting on — a hard desk amplifies it, a cushion absorbs it.
Questions

My phone stopped vibrating — is the motor broken?

Test it here first. A response means the hardware is fine and the cause is in sound or notification settings; no response points at the hardware.

Can it measure vibration from a machine?

Not this tool. Use the accelerometer readout, or record the accelerometer with the sensor logger to capture it over time.
