My right trigger button isn't working
It still registers but it doesn't have the same sort of springy feeling. Its worth noting I think started after a fall on the trigger. I'm guessing some piece of trigger assembly either broke or got out of alignment. Unfortunately I can only seem to find on trigger repair guides for the 3DS and those seem to be about replacing a flex cable not a mechanical issue (presumably they wore out the actual electrical switch component).
Is this a good question?
