For the s21, set up dnd schedule from 10pm to 9am.
But most days something beeps at around 7.30am. I look at my notifications and dnd is off. I see messages and emails, but nothing has a timestamp of the beep.
For example I get the notification sound at 7:37. I see dnd is off. I look at notifications and there are emails at 1:30 a.m., 4 a.m., and the weather update at 7:34 a.m.
How do I find out which notification it is?
Does DnD turn off because I touched the phone or something to look at the time, and it assumes that I am up?
A notification sounds be stored, for example it's thinking I'm up and plays all the sounds from 1 a.m. etc?
