On your Samsung Galaxy S9 you will receive various app notifications such as new incoming messages, special offers, warnings and much more.
The variety of notifications is very large, so you may want to disable them for some apps.
How this works on the Samsung Galaxy S9 in detail, we would like to explain this to you here:
