The newest form of security on the Galaxy S8+ is the iris scanner. This allows you to use your eye as the unlock method, just like you’ve seen on TV shows and movies. It’s a very cool feature when it works. If you wear glasses or contact it might not work as well. Here’s how to set it up.
- Go to Settings > Lock screen and security
- Select Iris scanner
- Read instructions and tap Continue
- Hold your eyes in the viewfinder
- Tap OK when complete
