Random notification sounds after updating to Android 8.0

[Android Central Question]

I have the Note 8....yesterday I updated to Android 8.0. Ever since the update, I've been getting random notification sounds, without any actual notifications. Anyone else experiencing this? It's getting quite annoying

Try turning BT off. Did it help? If so, there are devices trying to connect to your phone (either re-pair your BT devices or turn off the device being discoverable).

I get these to on occasion and I don’t have bt on plus I get random notification vibrations but there’s nothing there.
