Why doesn't my controller register a button command?

Example: my A button doesn’t register when I press it

• Does the button spring back up when you press it down?
  
  
  • If not, the button is damaged. The controller will need to be replaced
    
    
  • If it does, there could be grime or dirt stuck in the button housing. Use a cotton swab dipped in alcohol and wipe around the area.
