Are you using the Samsung keyboard? If so look on the keyboard for a setting icon it should look the same as it looks on the mic icon. Or just long press on the buttons near the space bar, that might give you the settings option.
Did you fully delete the settings, or did you just disable the buttons that lead there? There are so many things that depend on settings, do they work? WiFi, Bluetooth, uninstalling apps, app info and more...
Out of curiosity, what do you gain in deleting settings?
