Xbox controller bumper

The Right and left bumper are still there, considering that the bumpers replace the white and black buttons originally on the first xbox controller.

The bumpers on my launch day Series 1 Elite Controller finally broke a few months ago. Was disappointed that an otherwise perfectly functioning controller (never had the grip issue with mine) was rendered useless because of the poor design of the bumpers.
All the development that went into the Elite and no effort was made to improve this inherent weakness in all Xbox One controllers. I repaired it myself with a replacement bumper from ebay. Never had bumper issues with any of my 360 controllers.

i mentioned my first controller being broken because the bumper broke and the second controller is the only controller with a working bumper

Please clear your system cache and then roll back the most recent update. Go to Settings>System>Storage and put in the following button code on your controller: Left Bumper, Right Bumper, X, Left Bumper, Right Bumper, X

After your Xbox restarts, accept to redownload the update.

that happened to me, but the left bumper of a controller, i realized that was because an internal part of the bumper broke, so depending of the button it could have different solutions, for example what i had to do was to buy another bumper and I open
the controller and put it myself
