I just replaced my iPhone’s display. The display is working fine, but when the phone is plugged in to a computer, the touch screen wouldn’t detect any touches or have ghost touch. I tried to reboot the phone, re-seat the display cables, wipe/clean the display, and removed the screen protector, but I still experience the same issue.
Edit: I also tried to plug it to another computer, but still experiencing the issue.

You would need to rule out the screen so I suggest trying a replacement one and see if it behaves the same.
这个答案有帮助吗？
@imicrosoldering The original screen also has ghost touch, because it was dropped and it got cracked. The crack is above the display, near the front camera and speaker.

I tried to clean the contacts of the mainboard and the display cable using a toothbrush with isopropyl alcohol, and this had improved and it now reads some of my touches, but the are still some ghost touches.
