More features and improvements
Color palette
Customize your phone with unique colors based on your wallpaper. Your custom color palette now appears in more apps, including apps provided by Google.

More widely available keyboard options
Keyboard layouts, input methods, and features for specific languages are now available in more regions, so you can type easily no matter where you are. You can always switch back to your previous layout in Settings.
Customize your sound balance
In Accessibility settings, you can adjust the left/right sound balance for connected devices, such as speakers or headphones, separately from the sound balance for your phone speakers. This allows you to get the perfect balance out of your headphones without affecting how your ringtone and speakers sound.
New actions for Bixby Routines
You can now create routines that change your watch face or turn on advanced settings like Protect battery.
Customize your virtual memory
Choose the size of your phone's virtual memory with RAM Plus in Device care. Go with more to boost performance or less to save storage space.
Game optimizing service
CPU/GPU performance during early stages of gameplay will not be limited. (A performance management feature based on device temperature will be maintained.) The “Alternate game performance management mode” in Game Booster will be provided. 3rd party apps to bypass the Game Optimizing Service will be allowed.
We recommend that you update the Game Optimizing Service app to the latest version.
