Under-Display Face Unlock: Your Step-by-Step Guide to Android's Next Security Revolution

Introduction

Right as it’s been revealed that Google’s upcoming Pixel 11 probably won’t have new face unlock hardware, a new name is showing off some impressive under-display face unlock tech that could start showing up in Android devices as soon as next year. This breakthrough means your future phone could verify your identity through the screen itself—no notch, dot, or separate sensor required. To help you make the most of this feature when it arrives, we’ve prepared a clear, actionable guide. Follow these steps to understand, set up, and use under-display face unlock on your next Android device.

What You Need

• A compatible Android smartphone with under-display face unlock hardware (e.g., upcoming models from brands like Xiaomi or Oppo).
• Android 15 or later operating system.
• Sufficient ambient lighting (face unlock works best in well-lit environments).
• Clean screen and face (no heavy makeup or masks that cover key features).
• Optional: A backup unlock method (PIN, pattern, or fingerprint) for added security.

Step-by-Step Guide

1. Step 1: Confirm Your Device Supports Under-Display Face Unlock

   Before you begin, verify that your phone has the necessary hardware. Look for official announcements from the manufacturer, check the product specifications under “Biometrics,” or search for “under-display camera” in your device settings. If your device is among the first to feature this tech (likely 2025+ flagship models), you’re good to go.

2. Step 2: Understand How the Technology Works

   Under-display face unlock uses a miniaturized camera and infrared sensor placed beneath the OLED panel. When you look at the phone, the screen above the sensor becomes transparent momentarily, allowing light to pass through and capture your face. No moving parts are required. This innovation maintains a full-screen design while preserving the convenience of traditional facial recognition.

3. Step 3: Set Up Face Unlock on Your Phone

   Navigate to Settings > Security & Privacy > Face Unlock. Tap Set up face unlock. Ensure your face is centered in the on-screen oval, tilt your head slightly, and follow the prompts until the system captures enough data. The process typically takes under 30 seconds. You’ll be prompted to choose a backup method—this is mandatory for fallback scenarios.

4. Step 4: Optimize Scan Quality for Accuracy

   For best results, hold the device at eye level, about 20–30 cm away. Remove sunglasses, hats, or anything that shadows key facial features. If you wear glasses, the sensor should still work through thin frames but may struggle with thick or mirrored lenses. Re-enroll under different lighting conditions (bright office, dim living room) to improve adaptability.

5. Step 5: Enable Face Unlock for Apps and Payments

   Once set up, you can extend face unlock to third-party apps such as banking, password managers, and payment services. Go to Settings > Apps > Special app access > Face Unlock Autofill and toggle on supported applications. For Google Pay or Samsung Pay, enable “Face authentication for payments” within the respective app’s security settings.

   

6. Step 6: Test Under Various Conditions

   Test face unlock in bright sunlight, low light, and darkness (if your phone includes an IR illuminator). If you notice delays or failures, re-register your face or adjust your phone’s angle. Under-display sensors may be slightly slower than dedicated camera modules, so patience is key during the first few uses.

7. Step 7: Maintain Security and Privacy

   Regularly update your phone’s firmware to benefit from security patches and performance tweaks. Never share your face data with apps that don’t explicitly need it. If you trade in your device, perform a factory reset to delete stored biometric templates. Consider using face unlock as a convenience—not as a sole gatekeeper for sensitive data—by pairing it with a strong PIN or password for critical scenarios.

Tips for a Smooth Experience

• Use a backup method: Always set a PIN, pattern, or password as a fallback. Face unlock can fail due to screen protectors, oily lenses, or direct sunlight.
• Keep your screen clean: Smudges or scratches on the area above the sensor can reduce accuracy.
• Update apps regularly: Many apps will add face unlock support only after you have the latest version.
• Beware of battery impact: Frequent unsuccessful unlock attempts can drain power. If you notice excessive battery use, disable face unlock temporarily.
• Wait for mature software: Early adopters may encounter bugs. Give manufacturers a few months to refine algorithms before relying on the feature fully.
• Be patient: Under-display technology is still maturing. It may not be as fast or reliable as dedicated sensor-based systems, but it’s a big step toward truly bezel-less phones.
