Can you unlock face recognition with a picture on Galaxy device

Last Update date : Apr 19. 2021

Face recognition lets you unlock your phone in one quick move. Use the Facial recognition feature to unlock your phone with your face.

When using face recognition to unlock your device, your phone could be unlocked by someone or something that looks like your image. The possibility of the exceptional cases where the current detector can mistake fake image as a live input, the decision logic was already applied to strengthen the anti-spoofing function.

However, there are technical limitations in coping with all spoofing attempts such as high-resolution images.

Thus we do not recommend the usage of face recognition for high-security authentication applications. As Face recognition is less secure than Pattern, Pin, or Password, we recommend using Fingerprint recognition, Pattern, Pin, or Password to lock the device.

Additionally, if you use your face as a screen lock method, your face cannot be used to unlock the screen when turning on the device. You must unlock the screen using a pattern, PIN, or password you set when registering the face. Be careful not to forget your pattern, PIN, or password.

Note: Device screenshots and menus may vary depending on the device model and software version.

Set up Facial recognition

Step 1: From Settings, tap Biometrics and security.

Step 2: Tap Face recognition. Tap Continue, and then set up a screen lock if you don't have one already.

Step 3: Choose whether you are wearing glasses, and then tap Continue

Step 4: Hold the phone 8-20 inches away and position your face inside the circle. Hold the position until the progress bar reaches 100 percent. If needed, remove your glasses to finish the process. When you're done, adjust your desired settings, and then tap OK.

You can now unlock your phone by just looking at it! However, if you’ve set up a lock screen with Face recognition, your screen may request a PIN, Pattern, or Password under the following conditions: 

  • At least once every 24 hours.

  • If 4 hours have passed without using the device.

  • If the device has been restarted.

Tips for Facial recognition

Consider the following when using face recognition:

  • Glasses, hats, masks, makeup, bangs, and beards can affect the recognition process.

  • Make sure you are in a well-lit area and the camera lens is clean.

  • Make sure your image is not blurry.

  • Face recognition is less secure than Pattern, PIN, Iris, or Fingerprint.
