Chosen Solution
I hope somebody can help! A while ago, i dropped my phone on a concrete floor which cracked the front and back glass. The glass on the front cracked leaving a small hairline crack on the screen conveniently across the circle on the screen where the dot projector is. Anyways, i used my repair skills and changed the back glass and screen today using all original apple parts (except the back glass obviously). To my surprise face id still shows the message ’There’s an issue with your iphones ability to use face i’d’ & ‘A problem was detected with the truedepth camera’ It is also worth noting that upon inspection, the dot projector was slightly dirty so i gently cleaned the dirt off with a q-tip, other than that no flex cables are torn and everything else works perfectly apart from face id and portrait mode (which keeps telling me to move further away). Please help! p.s. i also reprogrammed the screen :)
Hi From what you have said it sounds like ether there is a dodgy camera/Face ID assembly connection to the logicboard or the Face ID components are damaged in some way I would first try and reseat the camera/Face ID assembly and if hat doesn’t work reasearch If the individual components in the Face ID system can be replaced Hopefully this helps Thanks:-)
