Hi, I am having tha same problem with my S20 Ultra using WhatsApp. This phone has many problems. Pictures taken from nearby are also blurred. Really disappointed!!!
Hi, I am having the same problem due to the edge lighting notifications. At the moment the only fix I could find is completely removing the edge lighting. I know, this sucks.
I have the exact same problem with my new Samsung Note20: it plays 2 notification sounds, one on top of each other: one is from the respective app and the other is the one I have assigned in the Settings --> Notifications. When I try to mute the Samsung Notifications in Settings, though, it mutes both notifications, so I end up with no notifications at all from any app. And overwriting this via the respective app doesn't seem to work either. I'm totally going crazy; in my old Samsung S9+ I never had this problem, it was so much simpler: in Settings, Notifications were silent, and yet, I could still receive selected notifications from some apps. 😫
I had the same problem on an A32. With Android 11, this is how I solved it:
On system Settings, Sounds, I chose the tone "Silent" for all notifications. Then on Apps, I enabled specific sounds for each one on the apps' notifications configurations. The Silent tone is still played, but is, well, silent. I guess that's the best Samsung could do, rather than fixing their imposed OS over Android.
