Install If You Play Games on Your Phone
If you play a lot of games on your Galaxy S9 or Galaxy S9+ you might want to give the Android Pie beta a try. Here's why.
Samsung's upgrades always come with improvements for existing features and the Android Pie beta delivers a nice one for Dolby Atmos sound.
If your Galaxy S9 is running Android 9.0 you get a new dedicated listening mode for games. According to Samsung, the new game mode enhances “gaming immersiveness and sound effects". Translation: It improves background sounds.
This is useful when you're playing a shooter and you need to hear the sounds around you.
