Gamepad & Controller Drift Inspector
Inspect analog stick drift with circular trajectory trails, configure deadzones, measure analog trigger pressure (0.000 to 1.000), and test rumble vibration motors.

How to Inspect Your Controller for Stick Drift
- 1
Connect your controller (Xbox, PS4/PS5 DualSense, Switch Pro, or generic USB/Bluetooth) and press any button.
- 2
Observe the dual stick canvas indicators. Let go of both thumbsticks; the crosshair should stay firmly within the center circle.
- 3
Adjust the deadzone slider to match your in-game settings (e.g., 5% to 15%) to verify if drift will affect your gameplay.
- 4
Depress the analog triggers (L2/R2) smoothly from 0% to 100% to ensure linear potentiometer response.
- 5
Click 'Test Vibration' to confirm rumble motors are firing correctly.
Controller & Stick Drift FAQ
What is stick drift and what causes it?
Stick drift occurs when worn potentiometer contacts or accumulated dust inside the joystick module register false movement even when the thumbstick is untouched.
Can stick drift be fixed by adjusting deadzones?
Minor stick drift (under 5-8%) can often be compensated for by increasing in-game deadzones. Severe drift usually requires cleaning with electrical contact cleaner or replacing the analog module.
