Crescent moon icon in notification bar s23 ultra

[Members_fnNMq5h]

Hi there. I'm looking for some advice. There was a crescent moon notification in my notifications bar which my girlfriend seems to think is do not disturb. I understand that the icon for do not disturb is a circle with a horizontal line through it. Do you know what the notification could be on galaxy s23 ultra?

I just turned on Do not disturb and I don't get a crescent moon icon. On my S23 ultra

Never seen this icon on mine, I wonder if it's anything to do with sleep in modes and routines.

@Members_fnNMq5h: If you swipe from the top of the screen to the bottom, is there anything in the Notification Panel that corresponds with the crescent moon symbol you're seeing? If not, please attach a screenshot of the icon, so I'm able to gain a better understanding of the issue.

Only thing I can think of at this point is Dark Mode, but I'm not sure if it's visible in Notification Panel?

It's the dark mode icon.

I was looking for an answer to this when I found your question. All the answers here are incorrect. It is the sleep mode icon.
