Due to the all too familiar cracking around the usb port, my screen has cracked to the point where it frequently separates from the main phone body. Unfortunately, this also means that the several connectors between the actual screen and the hardward behind the screen, as well as behind the screen and the main body, have come undone.

I have reconnected them manually several times with no problem, but now some cable is disconnected that is causing the phone to be unresponsive to touchscreen inputs, although the screen is displaying properly.

Does anyone know which cable is responsible for this data connection so that I can attempt to reconnect it? Barring that, is there any way that I can scroll through and select things like texts messages and emails without using screen input? Obviously I can open up the messaging app, but that's about it
