The a button sometimes stops working or it stops responding for a few seconds. What could be the cause of what I can do

Try screwing on the controller and inside you may see something that could prevent the button from being pressed. Otherwise you might have emptied something from a drink etc. And something could have caught the controller? Otherwise, maybe an electronics store can help. Otherwise, get a new controller: -D
