iPhone X Rear camera black screen 1x

Hi,

i’m from Italy, i repaired the back glass of an iphone x, when i turned it on again everything was working fine except the camera and the flashlight. This is the situation:

• flashlight DOESN’T work from control center
• camera DOESN’T work on 1x
• camera works on 2x
• when using camera on 2x (if needed) the flashlight works to take the photo

I already restored it twice, changed the camera module, changed the flashlight and the problems are still the same.

What else can i try?
