Fixing Joy-Con motion control issues often requires calibration. Go to 'System Settings' > 'Controllers and Sensors' > 'Calibrate Motion Controls'. Detach the Joy-Con from the console and follow the on-screen prompts: hold the Joy-Con flat and still when prompted, then rotate it 360 degrees slowly. If calibration doesn’t work, reset the Joy-Con: press and hold the SYNC button for 5 seconds, then reattach it to the console. Update the Joy-Con firmware: select 'Update Controllers' in the 'Controllers and Sensors' menu. For games with specific motion settings (e.g., 'The Legend of Zelda: Tears of the Kingdom'), adjust in-game motion sensitivity to match your preferences. If motion controls still fail, the gyroscope inside the Joy-Con may be faulty—contact Nintendo Support for repair, as this is often covered under the drift warranty.
