I usually have Atmos turned off on my s24fe. But I recently updated to oneui7 and everytime I connect any pair of headphones, it automatically turns back on to auto mode, I turn it off and it's fine for that session, but turns back on after I reconnect. Its great for some content. But I prefer not to use it. I saw the possibility of having routines and it turning on automatically. But I haven't made any, and if I go to look there is none.
Since you prefer it off, here are some tips to manage it:
Disable Dolby Atmos in Settings after connecting headphones: Unfortunately, there’s no current option to save your preferred Dolby Atmos setting per device, so you’ll need to turn it off manually after each connection for now.
Check for any active Bixby Routines: You mentioned no routines exist, so that’s good. Just double-check if any automation apps (like SmartThings or others) could toggle this setting.
Clear cache for the SoundAssistant app: Sometimes, clearing cache or data for SoundAssistant (if installed) can help with sound profile glitches: Settings > Apps > Show system apps > SoundAssistant > Storage > Clear cache.
