I receive a notification sound every 5 minutes, yet no notifications. Nothing shows in notification history log, and no icons appear when the sound is played. Only had this issues as of 8/12.
Yep, I have 2 S22u's and they both randomly do that sometimes. It can get really annoying at night. I wish there was like a history of apps that played a sound like we have for notifications and permissions used so we could actually track down the source.
