I want Sound alert when notification is received but no Pop up on top of screen . Currently , either both Sound and Pop up gets blocked Or both remains On . Earlier in Note 4 I did not have this problem.
Currently there's no default for it. However there are workarounds. Lightflow for example can be used not only for LED but for the audio and vibrate alerts, so you can turn off popup and sound in the settings, and Lightflow will handle it.
