I was replacing the battery in an iphone 5s and after I finished the phone turned on fine, the screen showed the apple logo, but then when it went to the unlock screen I couldn’t type in the password. It doesn’t respond at all to touch anywhere. All of the buttons function fine. I opened it several times and double checked the connections and I even ordered a new screen but have the same problem. Any thoughts? Thanks!
When you opened the phone you must have accidentally pulled the screen before disconnecting the ribbon cable your going to need to replace your screen.
