Controller messed up

So, because the title and video present, my controller’s proper joystick now has a thoughts of its personal. This began right now (atleast to my information) after I introduced my Sequence S over to a mates home and let him use the controller whereas I used my XB1 controller. I’m completely not sure of what incident may have prompted this, besides at one level within the night time my buddy unintentionally pulled my sequence s off it’s shelf accidentally not understanding there was a twine below him. The system itself appears completely advantageous and to my information the controller was untouched when this occurred, so I’m fully not sure of what may have prompted this. My XB1 controller works advantageous.
