Bent frame and now digitizer issues.

My daughter threw my iPhone 5S at the wall and it cracked the LCD only and bent the frame pretty bad. I installed a new screen from iCracked and it wouldn't work properly. I popped it back out of the frame and it worked ok so the frame is putting too much pressure on the LCD for the touch to work correctly.

I bent the frame back as much as I could and it's straight now but the touchscreen is still acting weird. As soon as i turned it on, I could feel heat from the logic board from under the camera area. And the touch screen works sometimes and sometimes it doesn't respond in the same spot.

Bad screen? frame problem? I usually have non responsive touch intermittently in the upper right corner.

Everything works fine except the intermittent touch screen issue and the heat coming from the connector area on logic board.

This is the only part that is bent now. It bent towards to rear of the phone right at the (-) volume button.

For example, when i swipe up on the settings screen, it will scroll a bit and snap back up while still swiping. Or I tap the Cancel button on the top right of the Messages app and it won't register at all. But the Camera app icon in the same spot, on the homescreen, will register just fine.

So I carefully took my motherboard out and this fell out with it. Not sure what it belongs to but is it a ground for the frame?
