Chosen Solution

So my colleague replaced the back cover and screen for an iPhone X. By replacing the back cover i mean that we bought a new frame with the back cover already in place. After the replacement the main camera no longer works and the front camera only works sometimes. I have tried the following:

  • Replaced the main camera.
  • Replaced the front camera.
  • Replaced the flash and on/off button cable.
  • Replaced the bluetooth antenna cable.
  • Checked all the connectors on the main board and all look fine.
  • Did a full reset of the phone 2 times. All this and nothing worked. I tried turning on the flashlight as well but nothing happened. Any idea what it could be and what to try next?

I’ve seen this a couple times on an iPhone X, and it seems to be a board defect. When you say you tested the board connectors, did you test voltage on the pins specifically?

Try to put it back in the original back case and when it works you know it is a fault in back case that you bought.
