Install for Better Text Over Wallpapers
Here's a small, but extremely useful change that might convince you to install Android 10 on your device soon after it lands for your Galaxy S10.
In its Android 10/One UI 2.0 change log Samsung notes that with the new software on board, you can see text more clearly against 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.
