ວິທີການແກ້ໄຂ Face ID ບໍ່ເຮັດວຽກໃນ iOS 18?

Apple’s Face ID is one of the most secure and convenient biometric authentication systems available. However, many iPhone users have experienced issues with Face ID after upgrading to iOS 18 . Reports range from Face ID being unresponsive, not recognizing faces, to failing entirely after a reboot. If you’re one of the affected users, don’t worry—this article explores the common reasons Face ID fails on iOS 18, practical fixes you can try.

1. Reasons on Why Face ID Isn’t Working on iOS 18

Face ID issues on iOS 18 are more common than you might expect. Here are the key reasons:

• Software Bugs After the Update

Each iOS version brings changes to how features like Face ID work. iOS 18 introduced tighter security settings, UI changes, and camera behavior updates that may cause temporary or persistent bugs.

• Face ID Settings Were Reset

iOS updates sometimes reset privacy and Face ID permissions. You may find Face ID disabled for apps or not set up correctly for unlocking.

• TrueDepth Camera Issues

Face ID relies on the TrueDepth sensor. If it’s covered by a screen protector, case, dirt, or smudges, it won’t function properly.

• Require Attention for Face ID is Too Strict

The “Require Attention” setting may have been enabled by default in iOS 18, which requires your eyes to be clearly open and looking at the screen. This can lead to recognition failures in low-light or when wearing sunglasses.

• Restrictions or Screen Time Settings

If Screen Time or Content & Privacy Restrictions are active, they may block Face ID for certain actions like unlocking the device or approving app downloads.

2. How Can I Fix The Face ID Not Working on iOS 18 Issue?

2.1 Restart or Force-Restart Your iPhone

The simplest fix is often restarting your phone. For stubborn issues:

Quickly press and release Volume Up > Quickly press and release Volume Down > Hold the Side button until the Apple logo appears

2.2 Use the Newest iOS 18 Version

Having issues? Apple often rolls out small updates, like iOS 18.1.1 or 18.5, to patch bugs and improve performance. Just check Settings > General > Software Update to make sure you’re up to date.

2.3 Check and Reconfigure Face ID Settings

Go to Settings > Face ID & Passcode and make sure Face ID is turned on for iPhone Unlock, Apple Pay, the App Store, and Password AutoFill. Disable “Require Attention for Face ID” if it’s interfering > Try Reset Face ID and set it up again from scratch.

2.4 Clean the TrueDepth Camera

If Face ID isn’t working well, gently clean the TrueDepth camera with a soft, lint-free cloth to ensure optimal functionality. Remove any case or screen protector that might block or reflect light onto the sensor.

2.5 Disable Screen Time Restrictions

If Screen Time is enabled, go to Settings > Screen Time > Content & Privacy Restrictions to check the settings. Make sure Face ID is allowed for unlocking and authentication
