How To Fix Eye Tracking Not Working On iPhone

You’ve set up your shiny new iPhone with all its latest accessibility features, excited to use the innovative Eye Tracking for hands-free control, only to find it… isn’t working. The frustration is real. Whether your device isn’t detecting your eyes, the pointer is erratic, or the feature is completely unresponsive, a non-functional Eye Tracking experience can feel like a significant setback.

This comprehensive guide is designed to walk you through every possible solution, from quick checks to in-depth fixes. We’ll explain the why behind the problems as much as the how to fix them, empowering you to get back to seamless, intuitive control. Our goal is to provide you with valuable, authoritative insights that go beyond basic checklists, incorporating practical expertise and a deep understanding of the technology.

What is Eye Tracking on iPhone and How Does It Work?

Before diving into fixes, let’s establish what we’re dealing with. Eye Tracking is a remarkable accessibility feature introduced in iOS 18 for iPhone 12 and later models, and iPadOS 18 for compatible iPads. It uses the front-facing TrueDepth camera (the same system that powers Face ID) to map the movement of your eyes.

By simply looking around your screen, you can control a pointer. A dwell timer allows you to perform actions like taps, swipes, and even custom gestures without ever touching your device. It’s a game-changer for users with motor or mobility challenges, but its utility for anyone wanting hands-free control is immense.

The system works by creating a detailed, on-device model of your eye and face. No data is sent to Apple’s servers; all processing happens locally, ensuring privacy. Understanding this helps troubleshoot: if the camera can’t see your eyes clearly or the software model is corrupted, the feature will fail.

Prerequisites: What You Need Before You Start

Let’s rule out the basics first. Eye Tracking has specific requirements:

Compatible Device: You need an iPhone 12 or later or a compatible iPad Pro/Air with a front-facing TrueDepth camera.
Correct Software: You must be running iOS 18 or iPadOS 18 or later. This feature does not exist in older versions.
Proper Setup: The feature must be enabled in Settings > Accessibility > Eye Tracking.
Physical Environment: Good, even lighting is crucial. The camera needs a clear view of your eyes.

If you’ve confirmed all of the above and it’s still not working, proceed with the structured troubleshooting below.

Step-by-Step Troubleshooting: How To Fix Eye Tracking Not Working

Follow these steps in order, from simplest to most comprehensive.

Step 1: The Immediate Quick Checks (5 Minutes)

Often, the issue is a simple oversight.

Restart the Eye Tracking Feature: Go to Settings > Accessibility > Eye Tracking and toggle the main switch OFF. Wait 10 seconds, then toggle it back ON. This resets the feature’s runtime process.
Check Your Lighting: Move to a well-lit room. Avoid strong backlighting (like a window behind you) that puts your face in shadow. The camera struggles in very dark or harshly contrasting light.
Remove Obstructions: Ensure nothing is blocking the front camera. Check for:
- Phone cases with a covered camera cutout.
- Screen protectors that encroach on the sensor area.
- Smudges, dirt, or fingerprints on the front camera module. Clean it gently with a soft, microfiber cloth.
Verify Your Position: Sit or position yourself so your face is roughly upright and within a normal viewing distance from the screen (about 1-2 feet). The initial calibration assumes a relatively forward-facing position.

Step 2: Recalibrate for Accuracy

If the pointer is jumping, lagging, or not appearing where you look, recalibration is key.

Go to Settings > Accessibility > Eye Tracking.
Tap “Calibrate” or “Reset Calibration.”
Follow the on-screen instructions meticulously. You’ll be asked to look at a series of dots.
- Pro Tip: Perform calibration in the lighting and seating position you use most often. Calibrating in bright daylight and then using the feature in a dim room can cause inaccuracies.
- Keep your head as still as possible, moving only your eyes to follow the dot.
After calibration, test the feature immediately. If it’s still off, try a second calibration session, focusing even more on smooth eye movement.

Step 3: Investigate Software Conflicts & Settings

Sometimes, other settings interfere.

Disable Other Pointer Controls: If you have Head Tracking or AssistiveTouch enabled with pointer control, they can conflict. Disable them temporarily (Settings > Accessibility > Touch > AssistiveTouch, or Physical & Motor > Head Tracking) to test if Eye Tracking alone works.
Check Face ID: Since Eye Tracking uses the TrueDepth camera, ensure Face ID itself is functional. Go to Settings > Face ID & Passcode and see if you can set up or use Face ID. If Face ID is failing, there’s a deeper hardware/software issue affecting the camera system.
Review Dwell Timer Settings: If actions aren’t triggering, your dwell timer might be too short or long. Adjust it in Settings > Accessibility > Eye Tracking > Dwell Timer. Start with a medium duration (e.g., 1 second) for testing.
Close Background Apps: A resource-intensive app could theoretically hinder the camera processes. Swipe to close all apps from the App Switcher and test Eye Tracking again.

Step 4: The Deeper Software Solutions

If the above fails, it’s time for more impactful software resets.

Force Restart Your iPhone: This clears temporary caches and resets system processes without deleting data. The method varies by model:
- iPhone 8, SE (2nd/3rd gen): Press and quickly release Volume Up, then Volume Down, then hold Side button until Apple logo appears.
- iPhone X & Later: Press and release Volume Up, press and release Volume Down, then press and hold the Side button until the Apple logo appears.
Update iOS/iPadOS: A bug might be causing the problem. Go to Settings > General > Software Update. Install any available updates. Apple frequently releases patches that fix accessibility feature bugs.
Reset All Settings: This is a nuclear option for settings-related issues but doesn’t delete your data. It will reset Wi-Fi passwords, wallpaper, and preferences, so be prepared.
- Go to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings.
- After the phone reboots, reconfigure Eye Tracking and calibrate again.

Step 5: Considering Hardware Issues

If every software step fails and Face ID also doesn’t work, a hardware problem with the TrueDepth camera system is possible.

Symptoms: Eye Tracking and Face ID both fail consistently. You might see error messages about the camera being unavailable.
Causes: Physical damage from a drop, liquid exposure, or a manufacturing defect.
The Solution: Contact Apple Support. You can:
1. Use the Apple Support app on your device.
2. Visit getsupport.apple.com.
3. Go to an Apple Store or Apple Authorized Service Provider.
  - Important: Repairs for the TrueDepth camera are complex and should only be done by certified technicians. DIY repairs often break other components.

Unique Insights & Proactive Best Practices

Going beyond standard advice, here are some less common tips and preventative measures:

The “Glasses & Contacts” Factor: The system works with most glasses and contact lenses. However, reflective lenses, progressive bifocals, or very thick frames can sometimes scatter light and confuse the sensor. Try calibrating both with and without your glasses to see which gives a more stable result. Apple has extensive documentation on this, confirming compatibility with a wide range of eyewear (you can read more on their Accessibility support page).
Create Multiple Calibration Profiles: Did you know you can save different calibrations? If you use your iPhone in multiple primary locations (e.g., a bright office and a dim living room), calibrate for each and save them with distinct names. Switch between them for optimal performance in each environment.
Battery and Performance Mode: When your iPhone is in Low Power Mode, some background processes are throttled. While Eye Tracking should work, it might be less responsive. For critical use, ensure you’re out of Low Power Mode.
Combine with Voice Control: For ultimate hands-free operation, pair Eye Tracking with Voice Control (Settings > Accessibility > Voice Control). Use your eyes to point and your voice to command (e.g., say “Tap” or “Swipe right”). This combination is incredibly powerful.

When To Seek Professional Help

You should contact Apple Support if:

All troubleshooting steps, including “Reset All Settings,” have failed.
Face ID is also not working, indicating a hardware fault.
You see visible damage to the front camera/sensor area.
The issue started immediately after a physical impact or exposure to liquid.

Conclusion: Regaining Intuitive Control

A non-working Eye Tracking feature can be disheartening, but it’s rarely an unfixable problem. By methodically working through this guide—starting with lighting and calibration, moving through software conflicts, and finally considering updates and hardware—you’re statistically very likely to resolve the issue.

The key is to understand that this is a sophisticated machine learning model running locally on your device. It needs a clear view of your eyes, proper initial training (calibration), and a stable software environment. By providing these, you restore not just a feature, but a profound level of independence and interaction with your device.
