The IPhone 18 Pro and IPhone 18 Pro Max are among Apple’s newest smartphones. Face ID is an important part of the experience, allowing users to unlock their device, authenticate purchases and sign in to supported apps.

Some early IPhone 18 Pro users reported problems with Face ID authentication, including situations where Face ID did not work correctly and the phone could freeze or restart. Apple has since released iOS 27.0.1 to address a specific Face ID-related restart issue.

So, what should you do if Face ID is not working on your IPhone 18 Pro? The first steps are simple: update the software, check the Face ID settings, and make sure the TrueDepth camera area is clean and unobstructed.

What Is the IPhone 18 Pro Face ID Problem?

Reports from some early users indicated that Face ID could fail during certain authentication situations. In some cases, users reported the device freezing and restarting after Face ID failed. Other reported symptoms included a “Face ID is Not Available” message during setup and problems with the Require Attention for Face ID setting.

This does not mean every IPhone 18 Pro has a Face ID problem. The extent of the reported issue is unclear, and Apple has addressed a specific Face ID-related restart issue through software.

Apple Released iOS 27.0.1 to Fix the Issue

The first thing IPhone 18 Pro users experiencing Face ID problems should do is check for the latest software update.

Apple’s iOS 27.0.1 release notes state that the update fixes an issue where IPhone 18 Pro and IPhone 18 Pro Max could unexpectedly restart when Face ID failed to authenticate. The same update also addresses other issues, including a touchscreen problem that could occur when Notification Center and Control Center were opened together.

How to Check for the Update

On your IPhone 18 Pro, go to:

Settings  >  General  >  Software Update

Install iOS 27.0.1 if it is available, then restart your IPhone and test Face ID again.

Face ID Still Not Working? Try These Steps

1. Check Face ID Settings

Go to Settings > Face ID & Passcode and make sure Face ID is set up and that the functions you want to use with Face ID are enabled.

2. Make Sure Nothing Is Covering the Face ID Camera

Dirt, a smudge, a case or a screen protector can interfere with the TrueDepth camera system. Check the area around the top of the display and clean it gently with a soft, lint-free cloth.

3. Check Your Screen Protector and Case

If you recently installed a screen protector or case, check its alignment around the camera area. A poorly fitted protector can obstruct part of the sensor area.

4. Make Sure Your Face Is Clearly Visible

Face ID needs to see your face clearly. Items such as masks or other objects that cover important facial areas can affect authentication.

5. Restart Your IPhone

A restart can sometimes resolve a temporary software problem. After restarting, try using Face ID again.

Can a Damaged IPhone Cause Face ID Problems?

Physical damage can require further inspection. If your IPhone 18 Pro has recently been dropped, has suffered screen damage or has another hardware issue around the front camera area, a professional assessment can help determine the cause.

The IPhone 18 Pro uses the TrueDepth camera system for Face ID. A problem involving the front camera or related hardware may require proper diagnostics rather than simply replacing a screen or another component.

What If Your IPhone 18 Pro Is Restarting?

If your IPhone 18 Pro is repeatedly restarting when Face ID fails, first make sure the device is updated to iOS 27.0.1. Apple specifically lists this restart behaviour among the issues addressed by that update.

If the restarting continues after the update, the problem may require additional diagnosis. Make sure important data is backed up before handing your phone over for repair or assessment.

Should You Repair or Replace Your IPhone 18 Pro?

A Face ID problem does not automatically mean that the entire IPhone needs to be replaced. The correct solution depends on the cause of the problem.

• Software or iOS issues
• Face ID settings
• An obstruction around the TrueDepth camera
• Screen or other physical damage
• Another hardware fault

A proper diagnosis can help identify the cause before repair work is recommended.
