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.
Im about to get into this exact repair. Thank you for going before me and the rest of us. I had done everything minus pulling off ALL the keys and began prying at the plastic base when I remembered how I butchered and hacked into my late Galaxy S 7 edge completly destroying every single part in my path because I refused to stop and look online for a guide. That wont happen again thanks to you...well at least I can blame someone else if its destroyed. Ill post my results asap but dont hold your breath.
You are very funny…thabk you..I probably would have ripped that touch button/flex cable right off the back starting out…due to the light you shined in advance I kbew to take heed when prying off that back cover.
