I am a repair shop and i have a iPod touch 5th Gen A1509 in for a screen replacement. Well i’m almost done and I noticed the front camera isn’t working. Meaning the app will open but it only shows a black screen

  1. Did a soft reset and nothing.
  2. Soldered a new camera on and still nothing.
  3. held the home and lock button down and still nothing.
  4. covered it with my finger and still nothing. The customer which is a friend of mine said it was working 2 days before they brought it in so i’m assuming i did something wrong. It was crashing as soon as you took a picture but that stopped and now it just wont let you take a pic and still has a black screen. Please any suggestions at all?

New iPod front camera worked when I got it , now black screen but back camera works
