iPhone Face ID Not Working? Causes and Easy Fixes

If your iPhone Face ID not working problem has suddenly appeared, you may find that you can no longer unlock your phone with your face. Face ID may fail to recognise you, stop setting up, or show a message saying that Face ID is unavailable.

This can be frustrating because Face ID is used for more than unlocking an iPhone. Depending on your settings, it can also be used to authenticate purchases, sign in to apps, fill in passwords and perform other tasks.

The good news is that Face ID problems do not always mean the hardware is broken.

Something as simple as a dirty camera area, a phone case blocking part of the sensor system, a setting that needs checking, or a temporary software problem can affect Face ID.

However, if Face ID stopped working after your iPhone was dropped, repaired, or exposed to liquid, the problem may require professional inspection.

In this guide, we will look at the common reasons Face ID stops working, what you can safely try at home, and when it is time to get your iPhone checked.

Why Is My iPhone Face ID Not Working?

Face ID uses Apple’s TrueDepth camera system to recognize your face. The system needs a clear view of your face and the sensors need to work correctly.

If something blocks the camera area, Face ID may not recognize you properly. There can also be software or hardware causes.

Common reasons include:

• Dirt around the front camera area
• A case or screen protector blocking part of the sensor area
• Your face being partly covered
• Face ID settings being changed
• The iPhone needing a restart
• An iOS software problem
• Damage after a drop
• Liquid damage
• A problem with the TrueDepth camera system

The first step is to work through the simple checks before assuming that repair is needed.

Clean the Front Camera Area

Start with the easiest check by looking at the top area of your iPhone where the Face ID sensors and front camera are located.

Check for fingerprints, dust, dirt or anything else covering the area and use a clean, soft microfiber cloth to gently clean the front of the phone.

Do not use sharp objects around the sensors.

Do not spray cleaning products directly onto the phone.

After cleaning the area, try Face ID again. A dirty or blocked camera area can interfere with the system’s ability to recognize your face.

Remove Your Case or Screen Protector

A phone case or screen protector can sometimes interfere with the camera or sensor area.

This is especially worth checking if Face ID worked correctly before you installed a new case or screen protector.

Remove the case carefully and test Face ID.

If you have recently installed a screen protector, check whether it covers any part of the TrueDepth camera area.

Apple recommends removing anything that might block the TrueDepth camera when troubleshooting Face ID.

If Face ID starts working normally after removing an accessory, you may have found the cause.

Make Sure Your Face Is Clearly Visible

Face ID needs to see your face.

Try using it without anything covering important parts of your face.

For example, check whether:

• A mask is covering your face
• Sunglasses are blocking the system
• A hat is covering too much of your face
• Your phone is being held too close or too far away
• Your face is outside the camera’s view

Hold the iPhone normally and look directly at the screen.

Try again in a well-lit room.

If Face ID works in this situation but not in another, the environment or something covering your face may be part of the problem.

Check Your Face ID Settings

Your Face ID settings are another important place to check.

Open:

Settings → Face ID & Passcode

You may need to enter your passcode before accessing these settings.

Check which Face ID features are enabled.

Depending on your iPhone and settings, Face ID can be used for things such as:

• iPhone Unlock
• iTunes & App Store
• Wallet & Apple Pay
• Password AutoFill
• Other apps

If Face ID is not working for one particular task, the problem may be related to that setting rather than the Face ID hardware itself.

Restart Your iPhone

A restart can sometimes fix temporary software problems.

If Face ID was working earlier and suddenly stopped, restart your iPhone and test it again.

After the iPhone starts, unlock it with your passcode first.

Then try Face ID.

This is normal after restarting. Your iPhone may require the passcode before Face ID becomes available again.

If Face ID starts working after the restart, the problem may have been temporary.

If it still does not work, continue with the next steps.

Update Your iPhone Software

Software updates can include fixes for problems affecting iPhone features.

Check whether your iPhone has an available iOS update.

Before installing an update, make sure important information is backed up.

After updating, test Face ID again.

Apple recommends updating the iPhone to the latest version of iOS when troubleshooting Face ID problems.

If the issue continues after the update, there may be another cause.

Reset Face ID

If Face ID still does not work, you can try setting it up again.

Go to:

Settings → Face ID & Passcode → Reset Face ID

Then choose the option to set up Face ID again.

Follow the instructions shown on the screen.

Try to hold the iPhone at the correct distance and move your head as instructed.

If the setup completes successfully, test Face ID by locking the phone and unlocking it again.

If you cannot complete the Face ID setup, that can be a useful clue.

It may indicate that the problem is not simply a recognition issue.

What If Face ID Cannot Be Set Up?

There is an important difference between Face ID failing to recognise your face and Face ID refusing to set up.

If Face ID occasionally fails, the problem could involve lighting, your position, your appearance, or something blocking the sensors.

If Face ID setup repeatedly fails, however, the hardware may need closer inspection.

Pay attention to when the problem started.

Did it happen after:

• Dropping the iPhone?
• Replacing the screen?
• Replacing another component?
• Getting the phone wet?
• Installing a new screen protector?
• Updating iOS?

Knowing what happened before the problem started can help identify the cause.

Face ID Not Working After a Screen Repair

If Face ID stopped working after a screen repair, do not immediately assume the screen itself is the only problem.

The TrueDepth camera system is located near the front of the iPhone and contains sensitive components.

A repair involving the front display area can sometimes require careful handling around these components.

If Face ID worked before the repair and stopped afterward, return to the repair provider and explain exactly what happened.

If the phone was repaired elsewhere and you are unsure what was done, a professional diagnostic check can help identify the problem.

Apple also provides information about genuine parts and repair history on supported iPhones.

Face ID Not Working After Dropping Your iPhone

A fall can cause more than a cracked screen.

Even when the display still looks normal, an impact can affect internal components.

If Face ID stopped working immediately after a drop, hardware damage should be considered.

Look for other signs such as:

• Cracked screen
• Damaged front camera area
• Face ID unavailable message
• Front camera problems
• Proximity sensor problems
• Screen problems
• Unexpected restarting
• Other features behaving differently

Do not press hard on the front camera area or try to move internal components yourself.

The safest approach is to have the phone inspected.

Face ID Not Working After Water Damage

Liquid exposure can affect many parts of an iPhone.

If Face ID stopped working after the phone was exposed to water, do not assume that drying the outside will solve the problem.

Moisture can reach areas that are not visible from the outside.

If other features are also behaving strangely, such as charging, speakers, cameras or the display, the phone may have broader liquid damage.

FoneDoc already provides water damage repair in Perth, including inspection, cleaning and component testing.

If liquid damage is involved, avoid repeatedly testing or charging the phone until you have received appropriate advice.

Why Does Face ID Say It Is Unavailable?

An unavailable Face ID message can happen for different reasons.

It does not automatically mean that your entire iPhone needs to be replaced.

Start with the basic checks:

1. Clean the front camera area.
2. Remove your case.
3. Check your screen protector.
4. Restart the iPhone.
5. Update iOS.
6. Check Face ID settings.
7. Try setting up Face ID again.

If Face ID still cannot be configured or remains unavailable, professional diagnosis may be necessary.

Can a Software Problem Stop Face ID?

Software can affect how features behave.

That is why Apple recommends restarting the iPhone and updating iOS when Face ID has problems.

However, not every Face ID problem is caused by software.

If Face ID stopped after physical damage or liquid exposure, hardware should also be considered.

The same applies if Face ID repeatedly fails to complete setup.

A technician can test the phone and determine whether the problem appears to be software-related or hardware-related.

What Should You Do If Face ID Works Sometimes?

Intermittent problems can be harder to understand.

If Face ID works in some situations but not others, pay attention to what changes.

For example:

• Does it work in bright light but not in a dark room?
• Does removing your case help?
• Does cleaning the front camera help?
• Does it work when you hold the phone farther away?
• Does the problem happen after the phone becomes hot?
• Did the problem begin after a repair or drop?

These details can help narrow down the cause.

Keep notes about the problem if it happens regularly.

That information can be useful if you later take the iPhone to a repair technician.

When Should You Get Professional iPhone Repair?

You should consider professional inspection if the basic troubleshooting steps do not solve the problem.

Professional help is particularly useful when:

• Face ID stopped working after a drop.
• Face ID stopped working after liquid exposure.
• Face ID will not complete setup.
• The front camera also has problems.
• You see damage around the camera area.
• Face ID stopped working after a repair.
• The phone shows a persistent Face ID error.
• Restarting and updating iOS made no difference.

Apple says that if Face ID still cannot be set up or the camera is not working properly after the recommended troubleshooting steps, service may be required.

How to Prevent Future Face ID Problems

You cannot prevent every hardware fault, but you can reduce some common risks.

Keep the front camera area clean.

Use a good-quality case that does not interfere with the sensor area.

Be careful when installing a screen protector.

Avoid dropping the phone.

Keep liquids away from the device.

If the phone is dropped or damaged, do not ignore new problems that appear afterward.

If Face ID suddenly stops working after physical damage, getting the phone checked early can help identify the problem before other faults develop.

Final Thoughts

When your iPhone Face ID not working problem appears, do not assume that the Face ID hardware is immediately broken.

Start with the simple checks by cleaning the front camera area, remove the case or screen protector, check your Face ID settings, restart the iPhone and update iOS.

If those steps do not help, try resetting Face ID and setting it up again.

If Face ID cannot be set up, or the problem started after a drop, repair, or liquid exposure, the issue may require professional inspection.
