Game controllers take a lot of abuse. From sweaty gaming sessions to spills and drops, some parts simply aren’t built to last beyond a few years. Here are some of the GamePad problems you’re likely to encounter and the fixes you’ll need for each.

The analog sticks in most gamepads rely on two potentiometer-based modules in the X and Y axis. Potentiometers measure the change in the voltage that occurs when you move the stick and rely on metal contacts that wear out over time. This can cause the joystick to eventually register a change in voltage even when the stick is at rest.

This is known as stick drift, and it’s a fate that awaits all but the most advanced gamepads out there. A better way to do this is to use hall effect sensors like the ones found on the latest electromagnetic joystick modules. Unfortunately, very few companies are using these yet including Sony, Microsoft, and Nintendo.

When a joystick starts to exhibit stick drift, you may notice movement on the screen even when you’re not touching the stick. It can make precise movement difficult, affect your aim in first-person shooters, and make driving in a straight line impossible. The only fix is to replace the joystick module with a new one.

Some systems, like the Nintendo Switch, feature joystick calibration in the console settings. This allows you to counter stick drift by resetting the deadzone. Keep in mind that this is a temporary fix. If the contacts have started to degrade, it won’t be long until stick drift rears its head again. A more permanent fix is to replace the joystick
