The Always-on display feature on the Samsung Galaxy S7 and S7 edge is new to the smartphone world. This year, phone makers like LG and Samsung decided to bake in software features that let the screen stay permanently on with minimal information constantly on display such as time, date, and basic notifications.
Samsung has updated its Always on Display feature by allowing users to customize the range of time that the feature should be active. Now users can only have their Samsung Galaxy S7s only stay permanently on for an allotted amount of time per day such as the full shift at work, or only for the night time or whatever works for you.
Its worth noting that if (on the S7 edge) the schedules for Always on Display and Night Clock overlap with each other, the phone will take priority to the Night Clock setting. To update your Always on Display for these new features, you should go to Settings > Display > Always on Display > About Always on Display > then install the update here.
