I seen comments about there being lines on the screen. some one said it was leaking and need to be replace. NOT TRUE! I found an iPhone 5s on a bus bench and the screen was unresponsive, with white lines running vertically .I disassembled the iPhone 5s after getting to the bracket that hid the flex cables I detached them all cleaned them with denatured alcohol and put them back together. The screen worked perfectly. I was then able to return the phone to its proper owner.
