Gamepad questions, fixes and result guides.
Practical answers for common gamepad problems, confusing results and setup questions — with a direct path back to the live test.
How do I test a controller for stick drift?
Connect the controller, release the sticks completely and watch the raw axis position and dead-zone visualizer. A persistent offset that returns when untouched can indicate drift or calibration issues.
Why is my controller not detected by the browser?
Some browsers expose a controller only after you press a button. Reconnect it, try USB instead of Bluetooth, press a button after page load and confirm that the browser supports the Gamepad API.
How can I test controller triggers and buttons?
Press each button and trigger while watching the live mapped values. Standard-mapped controllers get familiar labels, while non-standard controllers may show raw button numbers because their layout is not guaranteed.
Why is my controller not detected until I press a button?
Many browsers expose a gamepad to the page only after user interaction for privacy and security reasons. Press a controller button after opening the page.
How can I check controller stick drift?
Release the sticks and watch the raw axis values and dead-zone visualizer. Persistent idle offsets can indicate drift, though browser values are not a laboratory calibration.
How accurate is this gamepad tool?
Some browsers require pressing a controller button first before exposing gamepad data.
What should I do if the gamepad result looks wrong?
Reconnect the controller, press a button after page load, try USB instead of Bluetooth and confirm the browser supports the Gamepad API.
