Anyone who has spent much time with the Nintendo Switch gaming console has heard of one of the most common problems with the Joy-Con controllers: drift.
How to Fix Joy Con Drift on Switch Lite! | Mikeinoid
Joy-Con drift occurs when the controller incorrectly registers an input. For example, in-game your character may move in a certain direction even when you haven't touched the joystick.
Joy-Con drift more often affects the left stick than the right, possibly because this is usually the stick you use to move a character in a game, so it gets used more. Besides simple wear and tear, other causes of drift can include incorrect calibration, a connection issue, or dirt in the sensor.
The steps you take to fix Joy-Con drift depend on whether you're using the standard Nintendo Switch or the Switch Lite. Follow these suggestions to get your controller working again.
