10 Tech How-To

How to Get Face Unlock on Your Android

Guide 10-13006 · Updated · Step by step

Face unlock lets you skip the PIN or fingerprint and open your phone just by looking at it. Most modern Android phones have it built in, but the exact steps depend on your model and Android version. This guide covers the general process for stock Android, Samsung, and other major brands, plus what to do if you can’t find the option.

What You’ll Need

  • An Android phone with a front camera (all phones have one).
  • Android 6.0 or newer for basic face unlock; Android 10+ for improved versions.
  • Your phone’s lock screen security already set (PIN, pattern, or password) — most phones require this before enabling face unlock.
  • Good lighting when you set it up and when you use it.

Step-by-Step

  1. Open Settings. Swipe down from the top of the screen and tap the gear icon, or find the Settings app in your app drawer.
  2. Find the security menu. Look for one of these: Security, Security & privacy, Biometrics and security, Lock screen and security, or Face & fingerprint. On Samsung, it’s under Biometrics and security. On Pixel, it’s under Security.
  3. Look for Face Unlock. Tap Face Unlock or Face recognition. If you don’t see it, your phone may not support it (see Troubleshooting).
  4. Set a backup lock method. If you haven’t already, the phone will ask you to set a PIN, pattern, or password. Do that — it’s required for security.
  5. Enroll your face. Tap Set up face unlock or Add face data. Hold your phone at eye level, face the camera, and follow the on-screen instructions. You’ll usually need to move your head in a circle or keep it still while the camera scans.
  6. Confirm and adjust. After scanning, you may be asked to test the unlock. Some phones let you choose whether to require open eyes (recommended for security).
  7. Test it. Lock your phone and try unlocking with your face. If it doesn’t work, check lighting and make sure your face is fully visible.

Common Mistakes

  • Skipping the backup PIN. Face unlock is not a replacement for your main security; it’s a convenience. Without a PIN, the phone won’t let you enable face unlock.
  • Poor lighting. Face unlock uses the camera, so in dim or backlit conditions it may fail. Make sure your face is well-lit.
  • Wearing sunglasses or a mask. Many phones can’t recognize you with these, unless you’ve set up a secondary appearance (if supported).
  • Holding the phone too close or too far. Keep it about 8–20 inches from your face, roughly at eye level.
  • Not updating your face data. If you grow a beard, change hairstyles, or gain/lose weight, re-enroll your face.

Tips

  • Re-enroll periodically. Your face changes slightly over time. Deleting and re-adding your face data can improve accuracy.
  • Use “Require eyes open” if available. This prevents someone from unlocking your phone while you’re asleep.
  • For Samsung phones, you can often improve recognition by adding an “alternative appearance” (e.g., with glasses).
  • If you wear glasses, enroll with them on. Some phones handle glasses fine, but it’s safer.
  • Keep the camera lens clean. A smudged lens can cause failures.
  • Use face unlock for convenience, but keep a PIN for security. Face unlock is less secure than a strong PIN or fingerprint on most devices.

Troubleshooting

Face Unlock option is missing

Not all Android phones have face unlock. It’s common on Samsung, Pixel, and many Chinese brands, but some budget phones omit it. If you can’t find it in Settings, your phone likely doesn’t support it. You can try a third-party app like Smart Lock (Google’s built-in feature) which uses face detection to keep the phone unlocked in trusted situations, but that’s not the same as a secure face unlock.

Face unlock isn’t working

  • Check lighting. Move to a brighter area or turn on a light.
  • Remove obstructions. Take off hats, scarves, or glasses that cover your face.
  • Re-enroll. Go to Settings > Face Unlock > Remove face data, then set it up again.
  • Restart your phone. A simple reboot can fix temporary glitches.
  • Update your phone. Go to Settings > System > System update and check for updates.

Face unlock works but is slow

This is common on older phones. Make sure the camera lens is clean and your face is centered. If it’s still slow, consider using fingerprint unlock instead.

Face unlock is insecure (on some phones)

Some Android phones use only the front camera for 2D face recognition, which can be fooled by a photo. If security matters, use fingerprint or PIN instead. Phones with IR or 3D sensors (like some high-end models) are more secure.

Frequently Asked Questions

Is face unlock safe?

It depends on the phone. Basic 2D camera-based face unlock is less secure than a PIN or fingerprint. Some phones have 3D or IR sensors that are more secure, but still not as secure as a strong password. For banking or sensitive apps, use a PIN or fingerprint.

Can I use face unlock with a mask?

Most phones cannot recognize you with a mask. Some newer phones (like certain Pixels) have a “mask unlock” feature that uses the area around your eyes, but it’s not universal. You’ll need to enter your PIN when wearing a mask.

Does face unlock work in the dark?

It depends. Phones with an IR projector (like some high-end models) work in the dark. Phones that rely on the front camera will need some light. If your phone has a “screen flash” feature, it may briefly light up the screen to help.

Why does my phone ask for my PIN sometimes even with face unlock?

Android requires you to enter your PIN periodically for security, especially after a restart or after a certain number of failed unlock attempts. This is normal and cannot be disabled.

Can I use face unlock for apps?

Some banking and password manager apps support face unlock if your phone has the proper API. Check the app’s security settings. If the app doesn’t support it, you’ll need to use fingerprint or PIN.

How do I turn off face unlock?

Go to Settings > Face Unlock (or Biometrics) and select “Remove face data” or toggle off “Face unlock.” You’ll still need your PIN to make changes.
