Best Samsung Galaxy S8 Tips & Tricks
The Galaxy S8 has a fingerprint scanner, which you would have been prompted to configure during setup. But the iris scanner can be a faster way to unlock the phone. Open Settings > Lock screen and security > Iris Scanner and follow the prompts. If you have not already done so you will additionally need to set up an alternative screen lock option, just in case the Galaxy S8 is unable to recognise your iris and you need to access the phone.
When prompted turn on iris unlock, then in the menu that follows enable ‘Iris unlock when screen turns on’. This will prevent you having to swipe up from the lock screen to access iris scanning mode, you just wake the screen and look at it.
Once the iris scanner is set up you can also add fun masks to the feature – check it out in Settings > Lock Screen and Security > Iris Scanner > Preview Screen Mask.
