This has happened before with my Day One controller in which I went back to GAME last year to get a controller which overtime, developed the same situation. All of a sudden today, I pick up my controller to play a game and as soon as I hold down the left trigger, it feels different. It feels extremely clunky in which it makes a clicking noise when pressed down and it definitely doesn't feel comfortable. When I shake the controller, I can sort of also hear something shake in the left trigger. Anything I can try? Or else I'll have to go back to GAME as I luckily have a 2 year warranty on my Xbox One in which I should hopefully get my 3rd controller again if that's the case and will probably have the same issue later on.
