Apple iPhone X users increasingly see the message – Face ID is not available, try again later. Your very expensive iPhone X is faulty and needs replacement.
Apple is aware of the issue and has sent an internal (read secret) document to its Genius Bar repairers.
An internal document sent to Apple Stores and Apple Authorized Service Providers advises them to first run diagnostics on the iPhone X’s rear camera. If it shows a fault then repair the rear camera to try to resolve the Face ID front camera problem. If the issues persist, replace the whole unit.
The document reads: To provide the best customer experience, if a customer reports that their iPhone X is having Face ID issues, you may be able to resolve the issue with a rear camera repair. Run AST 2 on the customer’s device to check the camera. If the diagnostics find issue with the camera, perform the repair to see if the issue is resolved. If the issue is not resolved, perform a whole unit replacement instead of a same-unit display repair.
It seems crazy to repair a rear camera to fix a front Face ID camera issue. Apparently, the telephoto sensor processes the 3D Face ID image.
Users on various forums are happy that Apple has deemed it a replaceable problem, albeit that they have to back up and restore to a new phone. Apple initially thought it might have been an issue with an update to iOS 11.2
Apple will incorporate Face ID on its iPhone 9 series for release in late in 2018. This will replace touch ID.
GadgetGuy’s take – Apple Face ID may have a flaw
The internet is awash with hundreds of thousands of articles about Apple Face ID failing. The prime issues include
It might not work if you just switched on the device or restarted it
When the iPhone X is not unlocked in the last 48 hours
If after 6.5 days of no use you not unlock with Face ID
A remote command accesses your iPhone X
If your face doesn’t match five times
Once you power off or click emergency SOS by holding and pressing the volume control and side button instantaneously for 2 seconds
If you iPhone X charge is below 10%
Well, we have not seen any of these issues but do not doubt that they are real. What it simply means is where there is smoke there is fire. We covered Apple’a excellent facial recognition technology here.
