DualShock 4 Tester

The DualShock 4 tester focuses on DS4 layout checks, drift symptoms, trigger behavior, and browser mapping differences. It is useful for repair verification and used-controller inspection.

Vibration Test

User-triggered rumble presets

Vibration is not exposed by this browser or controller.

Vibration depends on browser, connection, driver, and device support.

Controller Health Summary

Connect your controller, press any button, then move both sticks to start the test.

Compatibility caution

Safari, Firefox, Linux, mobile browsers, Bluetooth adapters, and third-party drivers may expose incomplete features.

WebHID compatibility helper

Optional read-only permission prompt for listing HID devices. No firmware, calibration, or hardware-write operations are performed.

Trust note: Independent tool; no official PlayStation affiliation.

DS4 layout and common symptoms

Check face buttons and D-pad first, then compare L2/R2 pressure and both stick centers. If the page shows a constant offset at rest, run a drift sample and compare results after reconnecting.

Repair shops can use the local report as a simple before-and-after note, but it should not replace professional inspection.

  • Watch for worn stick modules, sticky shoulder buttons, and inconsistent trigger peaks.
  • Use raw mapping if labels differ from your game.
  • Do not treat browser results as a warranty decision.

Browser and hardware limits

Gamepad API support, haptic feedback, MediaRecorder, and WebHID are exposed differently across Chrome, Edge, Firefox, Safari, Linux, mobile browsers, USB, Bluetooth, and third-party drivers. For DualShock 4 Tester, treat that limit as part of DualShock 4 tester guidance rather than as a separate verdict.

A missing feature in the browser does not prove that the controller is damaged. Use the live readings as diagnostic hints and compare results across connection methods when possible. On this DualShock 4 Tester page, compare that note with the live module that matches buttons, sticks, triggers, drift, vibration, microphone input, compatibility, and report output.

DualShock 4 tester checks that matter

A DualShock 4 tester should focus on the parts that often age first: stick centers, L2 and R2 travel, shoulder buttons, stick clicks, and the face buttons used most often. Run the DualShock 4 tester over USB first if you are verifying a repair, because Bluetooth can add driver and pairing variables.

Use the DualShock 4 tester as an independent browser snapshot, not as an official PlayStation result. If Share, Options, touchpad click, or rumble behaves differently from a console, compare another browser and connection mode before deciding that the DualShock 4 tester has found hardware damage.

  • Start the DualShock 4 tester with basic button response.
  • Check both stick centers before judging drift.
  • Save a DualShock 4 tester note when buying a used pad.

Used DS4 inspection notes

When using a DualShock 4 tester for a used pad, spend extra time on the stick clicks, charging port stability, and L2/R2 travel. These areas often reveal wear before the face buttons do. If the DualShock 4 tester result looks good over USB but Bluetooth drops inputs, note the connection difference instead of assuming a bad repair.

  • Check the same DS4 after sleep and reconnect.
  • Record mapping differences before changing Steam Input.
  • Pair test notes with a visual shell inspection.
Quick workflow
  1. 1. Connect by USB or Bluetooth.
  2. 2. Press any button to activate detection.
  3. 3. Compare buttons, sticks, triggers, drift, and report output.
Privacy

Controller input, microphone recordings, and local reports stay in your browser unless you copy or download them.

FAQ

DualShock 4 Tester FAQ

Can this verify a DS4 repair?

It can help compare symptoms before and after repair, but it cannot guarantee the repair quality or hardware condition.

Does it test the DS4 gyro?

This version focuses on Gamepad API inputs. Browser motion exposure is inconsistent and not treated as a repair signal.

Why does my DS4 ID look different?

The browser reports IDs through operating system and driver layers, so naming can vary.
