Hello everyone,
I am having somewhat the same problem as cstr8. My sister owns an ipad 4 and I recently replaced her digitizer. After completing my repair, everything worked perfectly except the home button. Then, I opened it again, unplugged the home button/charging port flex cable and plugged it back in.
Still didn't work but I realize at this point that when I pressed the unglued digitizer on the two metal pin, it worked just as if I pressed the click button. It's weird to me because the button seems to work (when I press the little piece onto the two metal pin) but it does nothing when it's well pressed and I used the click button.
Thank you for you help, it is very appreciated, have a nice day!
Alex
