For me it’s the first thing i learned how to self host: Nextcloud …which in turn allows me to sync Joplin notes, which I use constantly

I’ve found Routines to be one of the most important features with Samsung - set up a car mode to auto run when charging AND connected by bluetooth to a specific device …and have it set the brighness dependant on the time of day. Turn location off completely unless certain apps are opened. Protect your battery if charging overnight …but go into power saving mode should charging stop for some reason. I find it invaluable. Even more powerful when used with Routines+ add-on

Looks OP has solutions but it looks like Routines also has options to separate sound on app specific basis
