Just got the s10e. I want to change the text message notification to something I have downloaded but don't know how. I was able to with the ring tone but not text messages. Please let me know how to do this. Thank you
Go to the folder where the notification tone is, long press on it and select move. Navigate to the Notifications folder on internal storage and select paste. You should be able to find it then.
Glad you got it solved.
