How to fix stick drift
Work from the cheapest step that can change the resting number: firmware, deadzone, cleaning, then a new stick module.
What to check first
Software can hide a small offset. It cannot rebuild a worn track. If a 3-second sample stays over 0.12 after you disconnect Steam Input, stop tuning sliders and plan a repair. Blow into the stick only adds moisture.
- Update official firmware where the maker offers it.
- Set the in-game deadzone just above the measured radius.
- Replace the module when the number does not fall.
Confirm the reading on the live tester before you buy parts or change firmware. The number on that page is what your browser actually receives.
A practical next step
Repeat the same test after each change and write the resting radius down. A fix that does not move that number did not fix the sensor. If the offset stays above about 0.12 with your hands off the sticks, plan a module replacement rather than another software pass. Model notes live in the controller library.
Frequently asked questions
Does this page change my controller?
No. GamepadTesters only reads the Gamepad API in your browser. Calibration writes, firmware updates, and stick swaps happen in the maker’s tool or at a repair bench.
