About Iris Unlock

You can set up HTC U19e‍ to unlock the screen with your irises when the screen is on.

Before using Iris Unlock

Before deciding whether to use Iris Unlock, here are a few things you need to be aware of.

  • Iris Unlock should not be used by children.
  • People with conditions triggered by light, such as epilepsy, should consult a doctor before using this feature.
  • If you experience dizziness, eyestrain, or unusual symptoms, discontinue use and use a different method to unlock your phone.
  • Iris Unlock is not a medical device, and should not be used for diagnosis or treatment of any medical condition.

For best iris scanning results

Follow these tips when using Iris Unlock:

  • Register your irises in a bright, evenly-lit environment. Once registered, you can use Iris Unlock in almost any lighting.
  • Avoid glare and direct sunlight.
  • Do not wear sunglasses or cosmetic contact lenses, such as colored contact lenses.
  • If you wear glasses, make sure to minimize glare when scanning.
  • Hold your phone at eye level and at a distance of 20 to 30 cm (8 to 12 in) from your face.
  • Make sure your phone is not tilted sideways while scanning.
  • Some screen protectors and cases might interfere with Iris Unlock.
  • Keep your eyes wide open and your phone still during scanning.
Note: Biometric unlocking methods such as Iris Unlock may be less secure. Your phone could still be unlocked by someone with similar biometrics. If you have any concerns, use other more secure authentication methods such as a screen lock pattern, PIN, or password.

Setting up Iris Unlock

  1. From the Home screen, swipe up and then tap Settings > Iris Unlock.
  2. If you haven't already set up a screen lock, you'll be asked to choose and set up a backup pattern, PIN, or password for unlocking your phone. See Setting a screen lock.
  3. If prompted, choose how you want to show notification content when your phone is locked, and then tap Done.
  4. Tap Register irises.
  5. Tap Next and follow the onscreen instructions to scan your irises.
  6. Tap Turn on to enable Iris Unlock.
Tip: By default, your phone automatically unlocks the screen when it recognizes your irises. If you prefer to swipe from the lock screen before the phone unlocks, tap Settings > Iris Unlock, and then turn off the Iris Unlock without swiping option.

Unlocking your phone with Iris Unlock

You need to be on the lock screen to use Iris Unlock to unlock your phone.
  1. If the screen is off, press the POWER button to wake up the screen.

    You'll see the icon on the lock screen.

  2. Hold your phone in portrait orientation at eye level and stare at the Iris Unlock camera until the phone unlocks. To find out where this camera is located, see HTC U19e‍ overview.
    • If Iris Unlock is successful, you'll see the blue icon then your phone unlocks.
    • If Iris Unlock is unsuccessful, you'll see the red icon. Tap it to try Iris Unlock again.
Tip: If Iris Unlock without swiping is turned off in Settings, you'll need to swipe on the lock screen after Iris Unlock is successful to unlock your phone.
