Chosen Solution
I repaired the iPhone 7 yesterday. But after assembling, booting The screen is displayed normally and the screen is not touched. Home button vibration and fingerprint recognition. Seek advice.
First I would check your connections. First I would try disconnecting the display, then carefully inspect the connectors for the screen as well as where it snaps in, checking for any damage to the pins or if the connector itself is bent/warped. I would also check to see if there is any foam around the connector that perhaps fell in, not allowing the connector to seat properly. If everything looks fine there, it is likely a faulty display or your display was damaged during installation. Where did you source it from? I would try getting a new one, and some of my favorite suppliers are repairpartsplus.com or mobiledefenders.com Good luck!
