Is your controller stick drifting?
Stick drift should be measured while the controller is untouched on a stable surface. Browser axis values are useful evidence, but game dead zones, response curves, controller mapping, and firmware can change what a game does.
If the same axis repeatedly rests away from center or moves by itself after neutral calibration, the controller may need a larger dead zone, native calibration, cleaning under manufacturer guidance, or service. One brief browser sample is not enough to condemn the hardware.
Run the GamepadMeasure neutral drift correctly
- Place the controller on a stable surface and do not touch either stick.
- Connect it, press one button so the browser detects it, then select the correct controller.
- Run neutral calibration and observe every axis for at least ten seconds.
- Repeat after moving each stick through its full range and letting it return naturally.
Read axis values with the right limits
- The Gamepad API commonly normalizes axes from −1 to 1, but the number and mapping of axes can differ by browser, OS, driver, and controller.
- A tiny non-zero resting value can be normal and may be hidden by a game's dead zone.
- Persistent movement in the same direction across repeated tests is stronger evidence than one spike.
- Trigger axes or motion sensors may appear beside stick axes on some controllers.
Compare the browser with the real use case
- Check the controller in the platform's native calibration or accessories utility when one exists.
- Compare the affected game's dead-zone and response-curve settings.
- Test wired versus wireless if both are officially supported.
- Update controller firmware only through the manufacturer's utility, then repeat the same neutral procedure.
Choose the least risky fix
- Drift only in one game: reset that game's controller profile before touching hardware.
- Drift across MeterSee, native tools, and several games: service or replacement is more plausible.
- Do not spray liquid into the controller or disassemble it unless the manufacturer procedure and warranty permit it.
- MeterSee cannot rewrite calibration, firmware, or game dead zones.
