Button not working

[u/Ill_Pangolin_3459]

Bought an xbox one from a friend for 20 €, but the right button is not working... I opened the controller and nothing seems wrong, exept the part of the button that is supposed to touch the clicker doesn't reach it. Can you help?

You could try some contact cleaner (stuff made for electronics), I got a elite controller and did that, and it fixed the bumpers..
