What causes iPhones to lose Face ID
Make sure that your face isn't blocked
You might need to hold your iPhone higher if you're wearing a face mask. If you wear a face mask too high or too close to your eyes, your iPhone might not unlock. Face ID works with many sunglasses, though Face ID with a mask isn't designed to work with sunglasses.
Can Face ID be damaged
Other problems with Face ID can result from damage to the TrueDepth camera system, including the dot projector. With water damage, we will often see the “unable to activate Face ID message” which prompts a flood illuminator transfer as described above.
Can dropping iPhone damage Face ID
In fact, the two most common reasons Face ID stops working is because your iPhone has been dropped or the screen was repaired by someone who damaged the Face ID components in the process. If this is the case, you will likely need to schedule for a repair, or consider replacing your device with something new.
Why Face ID can be so easily damaged
Once water damaged or exposed to a relatively humid environment, there might be electricity leakage or short-circuit problem that can result in Face ID failure. What's more, most of the Face ID parts are made of glass. Once dropped, Face ID is most likely to be unavailable.
Is iPhone Face ID repairable
If damaged, Face ID can only be repaired by Apple, so work with care. Peel and separate the pull tab on the final adhesive strip, on the top edge of the upper battery cell.
How much does it cost to fix Face ID
Assuming your phone is out of warranty, cost of fixing this would be US$399 – Apple categorizes their repairs under battery, screen, or other – which water damage, Face ID/cameras fall into. You can book an appointment with a Genius to confirm the problem and price.
What is the failure rate of Face ID
Facial recognition has improved dramatically in only a few years. As of April 2020, the best face identification algorithm has an error rate of just 0.08% compared to 4.1% for the leading algorithm in 2014, according to tests by the National Institute of Standards and Technology (NIST).
How risky is iPhone Face ID
Face ID is designed to work with hats, scarves, glasses, contact lenses, face masks, and sunglasses. Apple claims there's a one-in-a-million chance someone else's face can unlock your iPhone. OK, that's good to know.

Can water disable Face ID
Judging by what we have learned during the teardown of Face ID, main circuits of the Face ID are exposed. Once water damaged or exposed to a relatively humid environment, there might be electricity leakage or short-circuit problem that can result in Face ID failure.
Does replacing camera fix Face ID
Replacing the front camera alone does not affect the function of the Face ID, while Face ID will be disabled when replacing the full front camera assembly. Before attempting the actual replacement, a new camera should be plugged in and tested in order to verify that this repair will fix the problem.

Is Face ID safer than fingerprint
Therefore, if given the opportunity to buy an Android phone that has facial unlocking or fingerprint security, if you're after safe use of your phone, it's likely better to try fingerprints.
What is the failure rate of Apple Face ID
Apple claimed the probability of someone else unlocking a phone with Face ID is 1 in 1,000,000 as opposed to Touch ID at 1 in 50,000. During initial setup, the user's face is scanned twice from a number of angles to create a complete reference map.
Can you repair Face ID
If damaged, Face ID can only be repaired by Apple, so work with care. Peel and separate the pull tab on the final adhesive strip, on the top edge of the upper battery cell.
Does Face ID still work after screen replacement
The screen itself isn't part of the Face ID system, but the earpiece speaker assembly mounted on it is, so if you follow the instructions in the guide and transfer the earpiece speaker assembly over to the new screen, then your Face ID should work fine.
Can Face ID get hacked
Or more specifically, your fingerprints and your face. In fact, there's a one in 50,000 chance of your fingerprint scan being hacked and a one in a million chance of your Face ID getting hacked.
Can Apple fix a broken Face ID
If it is a manufacturing defect and your phone is still under warranty, then yes, it will be a free fix.
Can I trust Apple Face ID
Security safeguards
Face ID uses the TrueDepth camera and machine learning for a secure authentication solution. Face ID data—including mathematical representations of your face—is encrypted and protected with a key available only to the Secure Enclave.
