Fixing Switch Pro Controller drift follows similar steps to Joy-Con drift. Start by cleaning the analog stick: use compressed air to blow dust out from around the stick, then wipe the base with a cotton swab dampened with isopropyl alcohol (70%). If cleaning doesn’t work, calibrate the stick: go to 'System Settings' > 'Controllers and Sensors' > 'Calibrate Control Sticks' and follow the on-screen prompts. Reset the Pro Controller by pressing the small reset button on the back (near the USB-C port) with a paperclip for 5 seconds. Update the controller’s firmware: connect it to the Switch via USB-C, then select 'Update Controllers' in the 'Controllers and Sensors' menu. For persistent drift, replace the analog stick module—you’ll need a Phillips screwdriver to open the controller and a replacement part from Amazon.
