Install for Better Text Over Wallpapers
This is a small, but useful change that might convince you to install Android 10 right away.
With the Galaxy S9's Android 10 update on board you can see now text more clearly against your phone's wallpaper.
This is because the One UI automatically adjusts font colors based on light and dark areas and color contrast in the image.
In other words, text becomes far more legible when you're using a background that uses light and dark colors. This is immediately apparent in places like the lock screen.
