iPhone Face ID Not Working
Phone Repair by admin

Face ID has become one of the most convenient features on modern iPhones, allowing users to unlock their devices, authorize payments, and access apps with just a glance. But what happens when it suddenly stops working? If you’re dealing with the frustrating issue of iPhone Face ID not working, you’re not alone. Many users experience problems with Face ID, and the causes can range from minor settings glitches to hardware malfunctions.

In this article, we’ll walk you through the most common reasons your iPhone Face ID might not be working and explain step-by-step how to fix it. Whether your Face ID stopped responding after a drop or simply isn’t recognizing your face anymore, we’ve got you covered.

Why Is My iPhone Face ID Not Working?

Before diving into the solutions, it’s important to understand why Face ID might stop functioning. Apple’s facial recognition technology relies on a TrueDepth camera system that scans and maps your face. If anything interferes with this process—hardware issues, software bugs, or even user habits—it can result in your iPhone Face ID not working as expected.

1. Face ID Not Set Up Properly

One of the most basic reasons your iPhone Face ID is not working is that it hasn’t been set up correctly or was accidentally disabled.

How to Check and Fix It:

  • Go to Settings > Face ID & Passcode
  • Make sure Face ID is enabled for the options you want (Unlock iPhone, iTunes, App Store, etc.)
  • Tap Set Up Face ID or Reset Face ID if it’s already set up but not functioning properly

If you’re prompted to move your face in a circle during setup, follow the instructions closely in a well-lit area for the best results.

2. Dirty or Obstructed TrueDepth Camera

The TrueDepth camera system, located at the top of your iPhone screen, is responsible for scanning your face. If it’s blocked or dirty, Face ID won’t work.

Signs:

  • Face ID fails even before attempting recognition
  • Message says “Face ID is not available”

How to Fix It:

  • Gently wipe the front camera area with a microfiber cloth
  • Make sure there’s no dirt, screen protector, or phone case obstructing the camera
  • Remove anything hanging over or around the notch area

A clean lens ensures accurate face recognition.

3. Face ID Doesn’t Work in Certain Conditions

Sometimes, iPhone Face ID is not working due to environmental or personal factors, like:

  • Wearing a mask (unless you’re using a supported iOS version)
  • Wearing sunglasses that block infrared light
  • Using Face ID in low light or extreme glare

What to Do:

  • Remove sunglasses or try in better lighting
  • Update to iOS 15.4 or later to use Face ID with a mask
  • Add an alternate appearance in Settings > Face ID & Passcode

Being aware of these limitations can help you work around them effectively.

4. Face ID Fails After iOS Update

iOS updates can occasionally cause temporary software bugs, including Face ID malfunctions.

Symptoms:

  • Face ID stopped working right after a software update
  • Settings show “Face ID not available” or it fails during setup

Fix:

  • Restart your iPhone
  • Check for new updates: Settings > General > Software Update
  • If the issue persists, reset Face ID and set it up again

Sometimes, reinstalling the latest update through iTunes or Finder (on Mac) can help if bugs remain. Also, if your phone has started acting up after updates, read our guide on why your iPhone 14 is so slow and laggy.

5. Hardware Damage to the Face ID Sensor

If your iPhone has been dropped or exposed to water, it could damage the TrueDepth camera or other Face ID components. This is one of the most serious reasons behind iPhone Face ID not working.

How to Identify It:

  • Face ID setup fails every time
  • You see the message: “A problem was detected with the TrueDepth camera”

Solution:

Unfortunately, hardware-related Face ID issues cannot be fixed at home. You’ll need a professional diagnosis and possibly a component-level repair.

6. iPhone Is Too Hot or Too Cold

Extreme temperatures can cause sensors to act up. If your iPhone is overheating or freezing, Face ID might not work until the device returns to a normal temperature range.

How to Fix:

  • Move your iPhone to a room-temperature environment
  • Avoid leaving it in direct sunlight or on car dashboards
  • Wait a few minutes and try again once it cools down or warms up

Apple recommends using iPhones between 32°F to 95°F (0°C to 35°C) for best performance.

7. Face ID Disabled After Too Many Failed Attempts

If Face ID fails multiple times (e.g., due to someone else trying to unlock your phone), the feature automatically disables itself for security.

Fix:

  • Enter your passcode to re-enable Face ID temporarily
  • If the issue keeps occurring, reset Face ID in settings
  • Make sure only your face (or a trusted alternate appearance) is enrolled

This is a protective measure, but it can feel like a glitch if you’re unaware of it.

8. Face ID Not Working After Screen Replacement

Did you recently get your screen replaced? Non-genuine parts or improper installation can cause Face ID to stop working, even if the screen itself is functional.

Why This Happens:

  • The Face ID system is paired with the original logic board
  • Third-party repair shops without Apple-authorized tools might disrupt Face ID functionality

What to Do:

  • Visit an Apple-certified technician or a professional repair shop that specializes in iPhones
  • Ensure OEM (original) parts and tools are used during any screen or front sensor repair

At Computer Emergency Room, we perform screen replacements while preserving Face ID functionality. If you’re also having display problems like iPhone videos not playing full screen, we can help with that too.

9. Software Glitches or System Corruption

Sometimes, the issue isn’t with the hardware or settings but with system-level glitches.

Fix:

  • Back up your iPhone
  • Perform a factory reset: Settings > General > Transfer or Reset iPhone > Erase All Content and Settings
  • Set up Face ID again after restoring

If Face ID works after a reset, the problem was likely with corrupted settings or system files. You can also read our step-by-step guide on how to fix a frozen iPhone screen if you experience other system-related problems.

When to Contact a Professional Repair Technician

If you’ve tried all of the above fixes and Face ID is still not working, it’s time for a hands-on inspection. Hardware damage to the Face ID sensor or logic board requires specialized tools and skills to repair.
