Phantom system notifications S21+?

[canucks4life]

Starting last night my S21+ has been doing a random notification? although it is not my default sound. Nothing appears on screen or in recent notifications except Android system.

Very annoying even while in do not disturb it persists...tried restart but starting doing it again just now 🤷

Hi, download nice catch app in the galaxy store then enable "vibration history" to know what app is causing phone's vibration

Also do you have "notification reminder" enabled in accessibility parameters ? That option make your phone vibrate every 3~15 min when you have a phone or message notification that you haven't checked

Check in Settings > Sounds & Vibration.. What is the Default Notification sound, & is that what you are hearing?

You could also go to Settings > Notifications & Look for Android System Notifications & set it to "Deliver Quietly", at least for the next 24 hours & see if you continue to get unknown Notifications or not.

I had a sound happen like that and couldn't figure out what it was. Turned out I wasn't wearing my watch and my phone was telling me I didn't have it with me🤣

2.We kindly request you to Check your Wireless emergency alerts.
If you received an emergency alert and did not clear it, you may continue to hear the alert noise.

From here, you can select the switch (es) next to the alerts you prefer to receive.
