Introduction

Face ID is one of the most useful features on an iPhone. It allows users to unlock their phones, access applications, and make payments using facial recognition. However, some users notice that Face ID stops working after getting their iPhone screen replaced.

This problem can be frustrating, especially when you are used to unlocking your phone quickly. Let's look at some common reasons why Face ID may stop working after screen replacement and what you can do about it.

1. Damaged Face ID Sensors

Face ID uses special sensors located near the front camera. During screen replacement, these components can become damaged if they are handled incorrectly.

Solution: Get your iPhone inspected by a professional technician who can check the Face ID sensors and related components.

2. Incorrect Screen Installation

If the replacement screen is not installed properly, it may affect the connections or alignment of nearby components.

Solution: Ask a qualified repair technician to inspect the screen installation and check whether all connections are properly fitted.

3. Damaged Internal Flex Cables

Small flex cables connect important components inside your iPhone. If these cables become loose or damaged during repair, Face ID may stop working.

Solution: A technician should carefully inspect the internal connections and identify whether a cable needs repair or replacement.

4. Low-Quality Replacement Parts

Poor-quality replacement screens or incompatible parts can sometimes create additional problems during installation.

Solution: Always choose a reliable repair service that uses compatible, quality replacement parts and follows proper repair procedures.

5. Software Issues

Sometimes, temporary software problems can affect Face ID functionality after a repair.

Solution: Restart your iPhone and check for available iOS updates. You can also visit Settings and check Face ID settings to see whether the feature is available.

6. Face ID Needs to Be Set Up Again

In some situations, Face ID settings may need attention after a repair.

Solution: Open Settings, select Face ID & Passcode, and check whether Face ID is enabled. If available, you can try setting up Face ID again. However, if the TrueDepth camera system is damaged or unavailable, resetting the settings will not fix the hardware problem.

When Should You Get Professional iPhone Repair?

If Face ID still does not work after checking the settings and restarting your phone, there may be a hardware issue.

A professional technician can inspect the TrueDepth camera system, flex cables, and screen installation to identify the exact cause. Some Face ID components are security-sensitive and cannot simply be replaced with ordinary parts.

Final Thoughts

An iPhone that stops recognising Face ID after screen replacement may have damaged sensors, loose connections, installation problems, or software issues. Getting the device checked by an experienced technician can help identify the problem and avoid further damage.

If Face ID is important for your daily use, always choose a professional iPhone screen replacement service that understands how to handle the device's original Face ID components.
