There are a couple of options for facial recognition on the Galaxy S10, and both are fast, but one is more secure. I recommend using the more secure method. Here's how.
First, go to settings. There are a few ways to get there, but a quick way is to swipe down your notification screen then touch the gear icon.
Next, touch "Biometrics and Security".
Next, touch "Face Recognition".
Next, touch "Continue".
Now, tell it if you wear glasses or not, then touch "continue".
Here is the important step! Deselect "Faster Recognition". Don't worry, facial recognition to unlock your phone will still be lightning fast, just way more secure.
