On your Samsung Galaxy S8 around certain apps frames are placed, so you can recognize them better. If you only want to see the app icon without a frame, you will find the appropriate setting in the following Android submenu:
From the Home screen, navigate to the app menu and click on "settings"
- Tap Display and scroll down to "Symbol Frame"
- Tap the entry and you will enter the next submenu
- Select "Symbols". Finished!
From now on you will only be able to see the app icons without a frame appearing. This makes the system of the Samsung Galaxy S8 optically slimmer.
