I replaced a iPhone 6 screen & the screen/camera/Speakers are all functional but the home doesn’t work at all - nothing. My client came to me with out a home button so I cannot test the original. Is the new button defective or is the software glitching out because it hasn’t had a home button in a while.
I would guess the home button to be the defective part.
Could be homebutton, but could also be the longflex running along the screen
Touch ID isn’t functional after an screen repair if the home button is replaced.
ensure the cable on the thermal plate is working, try another cable-ensure the socket where the home button is plugged into isn’t damaged- try a replacement home button know to work with the iphone six remember the touch id will not work -all other functions should.
