Home button not working after screen repair

I replaced my screen successfully and kept the same home button. All worked fine when testing before I physically popped the display back into the back frame, but when I did that the home button stopped working completely. No Touch ID and it doesn’t respond to touch.

I think I must’ve broken or knocked a part when reseating the screen. I’ve taken the button apart again and reseated the connectors but had no luck.

The casing has a slight dent at the bottom by the lightning charger so I had to use more force than normal to get it in, that’s probably why it broke!

Incidentally I also reseated my speaker & the device that measures light slightly incorrectly which I’ll fix or replace when I open the phone up again - I’m sure this is not related but just in case it is.
