I dropped my controller a while back and the left bumper was still functional, but barely hanging on. Just yesterday, I dropped it again, this time it completely broke off. I tried to contact Microsoft and it turns out my warranty expired. I would have to buy another one for $150 to get it replaced. Can someone help me fix it ?
You might be able to fix it if you are able to find a bumper assembly for the controller, as ifixit doesn’t sell bumpers, or have guides to replace it.
