Also..I’m fairly certain part of the home button functionality exists and passes through one of the two cables when you connect the screen. If that cable is torn or not seated it will cause problems with the homebutton. And at one point even tho I had ordered (like you) the full assembly figuring I’d save time.. I ended up pulling that old original camera and sensor and earpiece bundle off the original screen and installing it on the new one. This actually worked for me.. but I warn you.. that is and can be a very slippery slope opening a whole other world of problems and frustrations. I don’t care how easy these videos make it seem. That lil bundle of cables and pieces is crazy town. Good luck.
