You can do this on Android as well (manufacturer results may vary...) This is on Android 14, but I initially turned it on in an earlier version: 1. unlock the Developer options (you can search this; depends on OS version) 2. in Developer options, scroll down to "simulate color space", choose grayscale 3. back to main settings --> Accessibility --> advanced, there is an "accessibility button" option 4. set that to "color correction" Now I have a small icon (looks like a person) that I can use to toggle monochrome. Indeed it was someone I heard on a train who had this turned on for iPhone as described above for the same reason ("lowers the dopamine response", he explained to the conductor) that intrigued me into looking into it Samsung also has a decent automation infrastructure ("modes and routines"), so I set that up to automatically disable the color correction / grayscale in certain apps (camera, photos, maps, etc.)
