回答“White vertical lines and unresponsive touchscreen”You're not going to believe this... I had this page open in a tab for months, while I procrastinated over opening up my iPhone 5 for the same repair. This morning, my phone fell out of my pocket, and I (get ready for this) ran it over with my car. Not only did the phone survive, but the touchscreen problem is GONE. The pressure must have fixed the loose cable contact.
