1. If screen is off (say for 30s) then power saving mode is on.
2. I can set all my notification preview off in lock screen. Then a bixby routine is helpful like ..if connected to home wifi turn all preview of notifications (show all content)
3. If unlock by fingerprint 1 then full screen navigation Gestures on.
If unlock by fingerprint 2 then 3 button navigation bar.
4. Enable immersive mode for certain apps.
Other off topic suggestions-
1. Add app lock option (even in S series this is not there).
2. 3 finger swipe (top to bottom) to take screenshots.
3. Give proper network features (CA etc.) to all phones as supported by hardware.
