How to use Gamepad Stick Drift Test

Open Gamepad Stick Drift Test on the same browser and device you want to diagnose.
Gamepad pages use the browser Gamepad API; connect the controller and press a button to expose it.
Run the visible gamepad test controls and watch the live result area update before judging the hardware.
Repeat the test once or twice, then compare related InputLab tools if the gamepad behavior looks inconsistent.

How to read the result

Gamepad Stick Drift Test is most useful when you read the result as a practical browser diagnostic. Browser support, Bluetooth latency, driver mapping, and controller firmware can affect readings. A repeated pattern across multiple runs is more meaningful than one isolated spike, missed event, or visual artifact.
