Apple moved part of Face ID under the display on the iPhone 18 Pro and Pro Max. Clear glass works. Matte and privacy glass can stop Face ID from recognizing you. Here’s how to choose an iPhone 18 Pro screen protector that works with Face ID.

To make the Dynamic Island smaller, Apple moved Face ID’s infrared camera under the display, near the top-left corner of the screen. Apple’s support page now says the TrueDepth camera on iPhone 18 Pro models sits at the top of the device, towards the left corner.
That camera now sees your face through the screen and anything stuck to it. Clear glass lets its infrared light through. A matte finish scatters that light, and a privacy filter is built to block light at an angle, so Face ID can get slower or stop working.
YouTuber Dave2D saw exactly this: Face ID stopped working on his iPhone 18 Pro Max with a matte protector on, and worked with a clear one.
| Protector type | Face ID on iPhone 18 Pro | What to do |
|---|---|---|
| Clear tempered glass | Works | Safe choice |
| Matte (anti-glare, frosted) | Reported failures | Skip, unless it has a clear window over the Face ID camera |
| Privacy (anti-spy) | Apple says remove it if Face ID fails | Only buy one that says it supports iPhone 18 Pro Face ID |
| Clear iPhone 17 Pro Max glass on an 18 Pro Max | Same 6.9-inch screen | Fine; don't reuse privacy or matte |
Update, September 30, 2026: Apple released iOS 27.0.1 on September 28, and it fixes this bug. Apple’s release notes say iPhone 18 Pro and Pro Max models “may unexpectedly restart when Face ID fails to authenticate,” and the update fixes it. Install it from Settings › General › Software Update.
The bug showed up with iOS 27. Some iPhone 18 Pro and Pro Max owners saw the phone freeze and restart after a failed Face ID scan inside a protected app, such as Passwords, Wallet or a private Safari tab. 9to5Mac reproduced it. It was never tied to screen protectors, so there’s no need to peel off a clear protector over it. If your phone still restarts after a failed scan on iOS 27.0.1, contact Apple Support.
iOS 27.0.1 also fixes a touchscreen freeze that could happen when you open Notification Center and Control Center at the same time. If your screen still ignores touches after updating and it started right after you fitted a new protector, take the protector off to rule it out.
All three are clear glass sized for the iPhone 18 Pro. Each listing also has an iPhone 18 Pro Max size, so choose yours before you add it to your cart.

HD clear glass with an auto-align install frame. Two sheets means a crack is a cheap swap.
A magnetic alignment kit lines the glass up for you, and two camera lens protectors come in the box. One early buyer reports Face ID and touch working normally with it fitted.
Sapphire-reinforced clear glass with a one-pull install tray. UltraGlass adds a lifetime warranty covering installation, fit and accidental damage.
Need privacy glass? Skip privacy protectors made for older iPhones. Buy one that names the iPhone 18 Pro and says it supports Face ID. TORRAS says its Privacy Shield Ultra for iPhone 18 Pro, sold on the TORRAS website, is Face ID compatible. Whichever you buy, test Face ID the day it arrives, while you can still return it.
It can. For iPhone 18 Pro models, Apple's Face ID troubleshooting page lists removing privacy screen protectors. Choose one that says it supports iPhone 18 Pro Face ID, and test it on day one.
Not reliably. Face ID has failed with matte glass fitted and worked with clear glass. Skip matte unless the protector has a clear window over the Face ID camera and names the iPhone 18 Pro.
Yes, if it's clear glass. Both phones have the same 6.9-inch screen. Don't reuse a privacy or matte one.
Unlikely. The restart after a failed Face ID scan was a software bug, and Apple fixed it in iOS 27.0.1. Update from Settings › General › Software Update.
Apple's Ceramic Shield front is tough, but it isn't scratch-proof or crack-proof. A clear two-pack costs far less than a screen repair.
