On my Samsung S10e, I set the volume for Notifications at 100%, but after a single text notification, the volume automatically changes to mute. I have set the volume to 100% multiple times, but it keeps reverting to mute. Is there a setting I can utilize to keep this from happening?
Please try swiping down twice from the top of your screen. Look for an icon marked “Do not disturb”. Is it turned on? If it is, try turning it off.
