iPhone
X users after screen replaced won’t work anymore. Due to iPhone X drop or some accidents the
screen of iPhone X got broken and it was replaced at Apple customer store. After
the screen fixe and when I get home I notice an error message saying my Face ID
has been disabled. However the FaceId on iPhone X stopped working as it is
disabled now. Surprisingly the apple
employee ran diagnostics after repairing my screen and said everything was
perfect.

| iPhone X Face Id not working |
Surely
iPhone X FaceId not working is a hardware failure rather than a software bug. Not
all iPhone X users are complaining about FaceID disabled after the screen replacement
but most of users are facing the issue now.
Not only screen repair but iPhone X screen id is even not working after
a drop as some sensors seems to lose or broken. FaceId seems to be very
sensitive feature with iPhone X and Apple should work on this to make it more
robust in future.
What could cause the Face ID fail after screen replacement:
The
infrared camera and dot projector as the main parts of Face ID system are tied
to the unique logic board inside each iPhone X. The flood illuminator works
with the Face ID system and is tied to the unique logic board inside each
iPhone X, so it is quite possible that it failed after replacing in your iPhone
X.
Fix 1: Sensor flex cable
While
replacing the SCREEN(don't replace the sensor flex cable), the Face ID should
still work. if you replace the sensor flex cable, the Face ID may fail to start
again in iPhone X.
Fix 2: Make sure to copy firmware data
If you
replace iPhone 8, 8 plus or X screen you need to copy the firmware data of the
original screen into the new screen. The needed tool is under development. I
saw some working versions, what are tested and working with IOS 11.4 and 12.0
Beta. The screen data can be cloned only to OEM screens for now. Please take
you iPhone X to authorised dealer and discuss with them about this.
Fix 3: Take an Apple Genuine bar appointment
If your
iPhone X is new and FaceId stopped working without any reasons. Please take your iPhone X to Apple and as
this can be a hardware issue and ask for replacement.
