Luxury phone maker iPhone has revealed that its Face ID (a 3D-sensing face recognition system) isn’t perfect for the phone and has instructions for its stores and authorized service providers to repair or replace faulty devices.
The TrueDepth camera system housed inside the notch is what makes Face ID possible on the iPhone X.
The first step involves trying to repair the device by fixing the rear camera. MacRumors obtained a copy of the instructions:
In order 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’s unclear what the link between rear and front camera is, but it sure looks like an issue with the dual-lens camera on the back might hinder Face ID functionality. If the repair doesn’t work, then a full-device replacement is advised.
