The button is stuck in the “pressed” position. To get my 3DS to respond as if it weren’t being press, I have to pull the edge of the button up. When it goes back down, I do not hear the clicking sound the other 3 shoulder buttons make when they’re pressed. The button is stuck down on the right, away from the center of the system. I’ve uploaded some images as well. http://imgur.com/a/byG8P The first and 3rd images are of my L button, which isn’t broken. They’re there for quick reference.
I had this problem when I dropped my 3ds. what I did was (carefully) disassemble the button itself and put a very very very small piece of thin cardbordin between the black mechanical part of the button and the plastic that presses against it. Fixed it completely. I would have taken pictures or video, but all pieces are extremely small and very difficult to deal with. I don’t blame ifixit for not making a guide on the buttons lol.
Mine won’t stop clicking, most of the games are playable, but one is not. Think the issue is the zr key.
