I think all iPhone X has this issue.
Bring control centre down, and swipe back up from the home bar and it makes a clicky noise. It sometimes won't but most of the time it will. Happens sometimes when 3D touching icons on the home screen as well. Doesn't seem to be a hardware issue as 3D touch on the photo app has no issues.
Edit: Title is kind of misleading. I noticed the clicky 3D touch when previewing apps with 3D touch in the app store. But it's always clicky when doing the control centre thing.
