Mine fell while headphone was connected to 3.5 mm jack, broke the holder in audio board, and rb was little stiff after the fall. Had to send for repair, as I did not find any parts online. Also, my lb was little unresponsive because of Sekiro. So they fixed both bumpers and audio board. I think in the new design, lb and rb buttons (internal) are part of joystick, which will be convenient to fix.
