Notifications During Call - Blowing Out Ear Drum

[Ryan-WI]

I have "allow alarms/notification sounds in call" turned off. But it still does. And it's F'n LOUD!

Text messages for sure. I think sometimes it's a text notification reminder. Either way,, what's up with this? 

Using the built in Samsung messages app. Can't stand the Google messages app. I think Gmail is also beeping in my ear.

Thanks
