How to Fix Switch Controller Drift on Pro Controller: Calibrate and Clean

Pro Controller drift can be fixed with calibration and cleaning. First, calibrate the analog sticks in 'System Settings' > 'Controllers and Sensors' > 'Calibrate Control Sticks'—follow the on-screen prompts to align the sticks. If drift persists, use compressed air to blow debris out of the analog stick housing: hold the stick in a circular motion while spraying short bursts. For deeper cleaning, use a cotton swab dampened with isopropyl alcohol (70%) to gently擦拭 the stick’s base. Avoid disassembling the controller unless you’re experienced, as it may void the warranty. If all else fails, contact Nintendo for a repair or replacement, as Pro Controllers are often covered under warranty for drift issues.
