One of the best features i find in a samsung phone is double tap to wake, especially in note 10/10+ where the lock button is on the left instead of the conventional right side of the phone.
Similar to waking up the device by double tapping in an empty area on the screen. Samsung can also add double tap to sleep or switch off the display. This can become really convenient when using the phone lying flat on a surface or switching on the display just to glance at notifications. We have the option to double tap to wake the device, adding a double tap to sleep will add easy on screen handling of the whole device
