iPhone 11 Face ID Failure
iPhone 11 Face ID Failure

The iPhone 11 boasts a myriad of impressive features, and Face ID stands among its crown jewels. However, post a screen replacement, some users have reported a malfunctioning Face ID. This article aims to shed light on this issue and guide you through steps to restore the functionality.

Understanding the Problem

Connection between Screen and Face ID

The iPhone 11’s Face ID module, known as the TrueDepth camera system, is intricately linked to the display. Any alteration or damage during screen replacement can affect this system.

Why Replacement Might Disrupt Functionality

Often, the failure is due to damaged connectors, misalignment during screen replacement, or incompatible screen parts, affecting the Face ID module’s calibration.

Steps to Troubleshoot

Rebooting Your Device

A simple restart can solve a multitude of problems. Hold the side button and either volume button until the slider appears. Slide it off, wait a moment, and then turn your iPhone back on.

Resetting Face ID

If rebooting doesn’t work, navigate to Settings > Face ID & Passcode. Enter your passcode, then tap ‘Reset Face ID.’ After this, set it up again to see if the problem persists.

Professional Interventions

Authorized vs. Third Party Services

If you need warranty coverage on a repair then you should always prioritize an authorized Apple service center. Third party centers will not usually be able to honor warranty claims. Additionally make sure the repair center you go to can handle Face ID repairs properly as the procedure is complicated. Check their reviews and compare pricing to ensure that your phone will be in good hands.

Re-calibration and Diagnostics

If Face ID still fails post-troubleshooting, professionals can recalibrate the system or run diagnostic tests to pinpoint the issue.

Preventive Measures

Choosing a Trustworthy Repair Service

Ensure you opt for reputable repair services with positive reviews and a track record of successful screen replacements.

Regular Maintenance and Care

A protective case and screen guard can go a long way in preventing screen damages, thus eliminating the need for frequent replacements.


Can a third-party screen replacement affect Face ID functionality? Yes, third-party replacements may not always align perfectly with Apple’s specifications, leading to Face ID issues.

Is there a guarantee that Face ID will work after a screen replacement at an Apple Authorized Service Provider? While authorized centers use genuine parts and adhere to Apple’s guidelines, there’s no absolute guarantee. However, the chances of success are significantly higher.

How much does it cost to fix the Face ID issue if it’s related to a screen replacement? Costs can vary based on location, warranty status, and the specific problem. It’s recommended to check with the service provider for an accurate estimate.

Conclusion While a screen replacement is a common fix for many iPhone damages, it can sometimes inadvertently affect Face ID on the iPhone 11. By understanding the potential issues, taking preventive measures, and seeking professional intervention when necessary, you can ensure that your device remains in optimal condition.
