You forgot to mention how to enable the fingerprint sensor when you replace the home button. When you replace the home button the fingerprint sensor wont work. Not sure what Samsung does but it has to be a software flash to allow the new part to marry to the mother board. There are lots of how to articles and videos that are half assed and just give enough info to get you into trouble. Though I wouldnt pay Samsung $100 to replace a button, these facts should be included in the repair article. Im really surprised no one has the fix for this in the form of an APK. Ive seen lots of screen replacement videos and all are half assed that show you the wrong way to remove the screen digitizer. I ripped my home button and back buttons circuit because of idiots that post how to videos that skip these important steps. I wish I would have paid the extra $$ and had the local shop do my repair from the start. He told me that the sensor wont work after repair and so far he is correct.
