Stick drift and deadzone
Set the controller on a steady surface and do not touch either stick during the sample.
Test Xbox Series X|S controller sticks, buttons, D-pad, and triggers online. Compare USB, Bluetooth, or adapter behavior.
Connect with USB, Bluetooth, or a supported wireless adapter. Then press any controller button so your browser can expose it. Your readings are processed on this device.
Set the controller on a steady surface and do not touch either stick during the sample.
Rotate each stick slowly around the outer edge, then sweep the center in several directions.
Press and release every available control. Analog buttons show their reported value.
Use these values to spot unusual layouts. A blank standard mapping does not automatically mean the controller is defective.
Connect a controller to view raw data.
Browser haptics are not available for every controller, connection method, operating system, or browser.
Reports are stored in this browser. Sharing is optional and puts only the selected result in the link.
Diagnostic readings describe what this browser receives, not electrical measurements from the controller. Confirm important findings in the game or device where you plan to use the controller.
Use the live tester to check an Xbox Wireless Controller made for Xbox Series X|S. Standard XInput-style controls usually map cleanly in current desktop browsers, including both sticks, A/B/X/Y, bumpers, triggers, D-pad, menu buttons, and stick clicks.
Connection through USB, Bluetooth, or the Xbox Wireless Adapter can use different driver paths. If an input or vibration feature behaves differently, save a report for each connection under the same browser and operating-system conditions.
The Share button and firmware-specific features may not appear as a separate webpage input on every system. A missing browser input does not necessarily mean that button is defective on an Xbox console.
Confirm the controller appears and the reported name or identifier is plausible.
Press and release every button, D-pad direction, stick click, bumper, and trigger.
Run the hands-off drift sample, then sweep both sticks through their full range.
Disconnect and repeat in the connection mode you actually plan to use.
Verify any fault inside a supported game or console before making a purchase or repair decision.
The Share button is not browser-visible on every Windows and browser combination.
The operating system or browser may reserve it or omit it from the standard gamepad layout. Confirm the button in an Xbox console or supported Xbox Accessories software if needed.
Firmware and drivers can affect compatibility and connection behavior. Use the official Xbox Accessories app or console settings for supported firmware updates, then reconnect and retest.
Test the one you use for gaming. If troubleshooting, compare USB, Bluetooth, and the wireless adapter separately because their exposed features can differ.
