Face ID is a standout feature of modern iPhones, including the iPhone XS Max. It allows users to unlock their phones, authorize purchases, and more using facial recognition. However, if the Face ID feature fails, it can be a significant inconvenience. Here’s what you need to know about iPhone XS Max Face ID replacement.

Understanding the Face ID Mechanism

Face ID relies on the TrueDepth camera system, which includes an infrared camera, flood illuminator, proximity sensor, ambient light sensor, and a dot projector. If any component of this system is damaged or malfunctioning, Face ID may stop working.

Steps to Troubleshoot Face ID

Before jumping to a replacement, ensure it’s a hardware issue:

1. Check for Obstructions

Ensure the TrueDepth camera isn’t covered by a screen protector, case, or any debris.

2. Update iOS

Go to Settings > General > Software Update and install any available updates.

3. Reset Face ID

Navigate to Settings > Face ID & Passcode and select Reset Face ID. Then, set it up again.

4. Restart Your iPhone

Sometimes, simply rebooting the device can resolve minor glitches.

Face ID Replacement Process

If the above steps don’t work, you might need a Face ID replacement.

1. Apple Authorized Service Providers

It’s crucial to understand that Face ID components are paired to the individual device’s logic board for security reasons. Hence, replacing Face ID isn’t as straightforward as changing a screen or battery. It’s highly recommended to get replacements done through Apple or an Apple Authorized Service Provider to ensure the new Face ID components are paired correctly.

2. Cost Implications

If your iPhone XS Max is out of warranty or doesn’t have AppleCare+, you’ll likely incur a fee. Check Apple’s official website for repair costs or contact an authorized provider.

3. Backup Before Replacement

Always backup your iPhone XS Max before any repair. You can do this using iCloud or your computer.

4. Replacement Time

Face ID replacements can take anywhere from an hour to several days, depending on the provider’s availability of parts and expertise.

After the Replacement

After the Face ID components have been replaced:

  1. Test Face ID: Ensure it recognizes your face quickly and without errors.
  2. Restore Your Data: If you had to erase your device or got a replacement, restore your data from your backup.


Your iPhone XS Max’s Face ID is a complex system that combines hardware and software. While replacements can be done, they’re best left to professionals given the technology’s intricacy. Always consult with Apple or authorized technicians for any repairs related to Face ID.
