Can you unlock face recognition with a picture on Galaxy device

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.

Consider the following when using face recognition:

• If the front camera lens is not clear, face recognition may not work properly. Please clean the lens and try again.
• Glasses, hats, masks, makeup, bangs, and beards can affect the recognition process.
• Make sure your image is not blurry.
• Face recognition is less secure than Pattern, PIN, Iris, or Fingerprint.
• Make sure you are in a well-lit area and the camera lens is clean. When trying face recognition in the dark, screen brightness increases temporarily for better recognition. If you feel this’s inconvenient, please turn off the Bright screen option. On Settings, tap Biometrics and security > Face recognition, turn off Bright screen option.
• For enhanced security, the device only recognizes your face when your eyes are open. If you feel this’s inconvenient, please turn off the ‘Require open eyes’ option. On Settings, tap Biometrics and security > Face recognition, turn off Require open eyes option.
