My Samsung Galaxy finally changes its own settings when I need it to

My Galaxy phone handles the tasks I used to do myself. Now, at certain times of day, my phone already knows what to do. For example, you may want your phone to go into Do Not Disturb mode between certain hours to get some peace and quiet. I use Modes and Routines to set up my phone the way I want and move on to something more important. At first, I thought it was mostly about schedules. Then I started poking around and found setups that help me in different ways without me having to worry about them afterward.
