My phone is making a notification sound other than the one I chose and there are no notifications on the panel . It is very annoying. Could it be a phone **bleep**?
Hey, you can download nice catch by good lock (developed by Samsung employees) from the galaxy store, it is designed to find and catch the source of the notification in real-time and allow you to see what app sent it
If you did not find the source of the sound using the suggestion given by Or_D, I would suggest checking the recent notifications by going to Settings > Notifications > Recently sent, under this category you can find the recently sent notifications and how long ago it was received.
If that did not help, I would recommend sending an error report as soon as it repeats itself.
To send an error report go to Samsung Members app > 'Get Help' > select the "Error Reports" category > select the appropriate topic and then describe the phenomenon in detail, at the bottom of the page and make sure that sending the system log is marked V.
