iPhone X Face ID won’t detect faces
So I recently purchased a smashed Iphone X and an Icloud one in order to get a working one. I basically put the motherboard, front camera and the sensors from the screen into the Icloud one and everything works except from the fact when I try to set up Face ID. It tries to detect my face but nothing happens then proceeds to say Face ID is unavailable. Any idea what could be the problem? It lets me try and set it up so I know all the correct parts are there as it can activate it but it just can’t see my face
thanks in advance
Is this a good question?
