Great step by step articel thanks. I have just followed and replaced cracked screen on iphone X.

All went as per the diagrams and phone works fine except the front facing (selfie) camera no longer works. Weirdly the rear camera is fine but selecting the selfie camera shows a blury version of the rear camera picture! Any ideas what could cause that. It was definately working before the screen replacement but I have triple checked and no cables are damaged and all seated properly. What would cause the front camera to play up?
