When something breaks it's best to wait for it to fix itself or for the problem to go away. It works. For example my headphones (or, as they are apparently called, "earbuds"). After about a month of working rather fine the right one decided it's more fun if it starts buzzing. For about a week it buzzed away happily whilst I ground my teeth without much mirth but deciding that changing the headphones, especially as the current ones were still considered new, was too much hassle – and there you go – it fixed itself. Good things come to those who wait?
