My iPhone 4 has no touch after screen replacement.

So basically I bought an iPhone 4 CDMA Verizon screen replacement from you guys on Amazon and I replaced my iPhone 4’s cracked screen. However, when I was done with the repair the touch does not work. Everything else on the device works except the touch. I love this old phone and any working answer would be amazing.

a few things this could be

  1. Defective screen
  2. You knocked off a filter around the Display FPC. At this point it will be a motherboard repair needed.
