Dear all,
Problem with the home button for me too.
I bought a screen on ifixit for replacement on my iPhone 7.
No problem during the swap, but when I switch on the phone, it takes a long time and restarts two or times (apple logo then black screen then apple logo again).
Once it started, touche ID and home button don't work.
If I swap to the original broken screen, everything is fine, quick start, touch ID and HB work fin.
Do you have an idea ?
