Galaxy S9 User Guide: Tips, Tricks and How-Tos

Set Up Intelligent Scan on the Galaxy S9

How many ways can you unlock a smartphone? On Samsung’s Galaxy S9, the answer is five.

Samsung added a feature called Intelligent Scan in the S9 and S9+, which joins the traditional passcode in addition to the fingerprint sensor, face recognition and iris scanning features already baked into previous generations of the Galaxy S line.

Intelligent Scan combines facial recognition and iris scanning for a quicker, easier way to unlock your S9. It defaults to face recognition in bright sunlight and iris scanning in low light, or a combination of the two if both are difficult to detect.

Intelligent Scan is a lightning fast way to unlock your phone, but it’s not as secure as a passcode or fingerprint scan. (You can’t use Intelligent Scan to verify mobile payments, for example.) If you choose to use Intelligent Scan, you’re giving up a bit of security for the sake of convenience, which is something to consider.

Here’s how to set up Intelligent Scan. —Caitlin McGarry

1. Open the Settings app.

2. Tap on Lock Screen and Security.

3. Under Biometrics, tap Intelligent Scan. If you don’t have a PIN number set up yet, the S9 will prompt you to set one up.

4. Tap Continue on the verification information screen.

5. Now it’s time to register your face.Hold your phone 8 to 20 inches away and tap Continue. Make sure your face is centered in the circle on-screen.

6. After scanning your face, register your irises. You’ll want to do this inside. The S9 advises you to remove glasses and contacts, but I registered my irises while wearing contacts without an issue.

7. Make sure your eyes are centered in the on-screen circles.

8. Turn on Intelligent Scan after registering both your face and your irises.

9. Make sure Intelligent Scan unlock and Screen-on Intelligent Scan are toggled on so that you can quickly unlock your phone without having to swipe the screen first.
