Once you have setup your iris scanner on your Samsung Galaxy S8, it is a very quick and convenient way of unlocking your phone. To use the iris scanner you need to press the power button, then swipe to unlock and then you can use the iris scanner to unlock your phone. To enable the iris scanner when the screen is turned on go to Settings > Lockscreen & Security > Iris Scanner > turn on iris unlock when the screen turns on. This will save you a swipe and you will be able to unlock your phone when the screen is turned on.
As the Samsung Galaxy S8 has an on-screen home button. By default, the home button is present when the screen is turned off. To prevent burn-in from the home button, you are able to turn it off. To do this you go to Settings > Display > Always on display > select ‘Clock and Information’ only.
Fingerprint sensor gestures
With Android Nougat 7.0 you have fingerprint gestures. With this, you can swipe down on the fingerprint sensor for the notification panel. This may be easier especially on the S8+ as the display is quite tall. Go to Settings > search for finger sensor gestures > then toggle it on.
Custom Navigation Bar
For Android users going from a Nexus or Pixel device who are used to the back button being on the left-hand side of the home button. To change the orientation of the navigation buttons. Go to Settings > Display > Navigation bar. From here you can change the color of the navigation bar system wide, and also the orientation of the buttons.
The Samsung galaxy S8 and S8+ come with a 2K display (2160 X 1440), but out of the box the resolution of 1920 X 1080 which is full HD. To change the resolution of the display, go to Settings > Display > Screen resolution and drag the toggle to WQHD+.
Blue light filter
A recent trend in late 2016 and 2017 smartphones is having a ‘night mode’/blue light filter. This changes the hue of the display so that it isn’t as harsh on your eyes which allow you to sleep better at night. You can turn this on from Settings > Display > Blue light filter. You can toggle this on and off in the quick settings menus too. But an easy way of automating this to set up the sunrise to sunset feature so that it turns on and off automatically depending on the time.
