  1. Before you begin, you must have a Pattern, PIN, or Password set up on your device.
  2. Swipe up on the Home screen to view all apps.
  3. Tap Settings > Lock screen > Screen lock type.
  4. Tap the switch to turn on Intelligent Scan. You can also turn on Face and Iris recognition individually.
  5. Tap Continue and follow the on-screen steps to calibrate the Face and Iris recognition.
    • Make sure to stand in a brightly lit room for the best calibration and low light performance.
    • You'll be asked if you wear glasses. If you do, it will direct you when to put them on and take them off for the most accurate recognition.
    • If you're using Intelligent Scan in portrait mode, you'll need to move the red dot in front of your face for a proper scan.
