DualShock vibration in the browser
A sent vibration command only proves the browser accepted the call.
What to check first
Chromium usually exposes dual rumble for a DualShock 4. Firefox and Safari often do not. The vibration test says which case you are in. Command-line utilities talk to the device more directly and can succeed when the Gamepad actuator is missing. They are optional. They are not required to see buttons and sticks on this site.
- Hold the pad. A cushion eats small motors.
- Steam can mute rumble in a desktop layout.
- Adaptive resistance is not this rumble call.
Confirm the reading on the live tester before you buy parts or change firmware. The number on that page is what your browser actually receives.
A practical next step
Repeat the same test after each change and write the resting radius down. A fix that does not move that number did not fix the sensor. If the offset stays above about 0.12 with your hands off the sticks, plan a module replacement rather than another software pass. Model notes live in the controller library.
Frequently asked questions
Does this page change my controller?
No. GamepadTesters only reads the Gamepad API in your browser. Calibration writes, firmware updates, and stick swaps happen in the maker’s tool or at a repair bench.
