Hi, I want help in fixing my Xbox One S controller’s LB button. The LB button is fine but whenever i try to press it quickly i mean light clicking so it won’t respond but when i try the hard clicking so it wil respond. Please help me in fixing this.

You are probably going to have to go into the controller and clean the button contact. Use isopropyl alcohol and a q-tip. While you are in there, you might just want to clean the rest of them to avoid further issues. If this doesn’t work, you probably have a defective button and will have to replace it. It sucks, but it happens, I had to once on a DSi.
