Hello my friend. I have done that,but it keeps coming really loud,not all the time,but sometimes its very loud,even got volume assistant app,and that don't work .can someone help.
Sorry for resurrecting an old post but I'm having this issue with my s10. Volume sliders are as low as possible but the notification sound can be heard on the moon.
Did you ever find a solution to this?
I have the same issue on my S9. Started a few weeks back. I have disabled nearly every notification as they were driving me nuts with the high volume. Nothing I change seems to help get them back to normal.
