My iPhone 5s fell really hard the other day. The touch screen will become unresponsive randomly and with slight pressure near the top of the screen. I did a full restore and nothing worked. It becomes responsive again when I unlock it. The top part of the frame (on the back where the main camera with flash is) is bent and the top glass on the back is bending outwards. The black lines in the side of the phone are starting to look like acute triangles. I know it's not software because it happened in 8.3 and 8.4. What do you guys think? Is it the frame, the digitizer, and/or the lcd?
