Change Keyboard Theme auf Samsung
The Samsung keyboard starts in a light layout by default, which can look glaring in a dim room or at night. One UI stores the keyboard color scheme separately from the system dark mode, so switching your phone to a dark theme does not always change the keyboard automatically.
You can pick a fixed light or dark keyboard, or let Samsung Keyboard adjust itself with the Adaptive Theme option, which follows the color of the app currently in focus. This setting lives inside the keyboard's own settings, not in the general display menu, which is why many users miss it.
How to switch the theme
Open Settings ➔ General management ➔ Samsung Keyboard settings ➔ Theme ➔ Choose an option. Pick Light, Dark, or Adaptive Theme depending on how you want the keyboard to behave.
If the keyboard still looks wrong after changing this setting, check whether a separate keyboard theme pack is installed, since an installed pack can override the built-in Light, Dark, or Adaptive choice.
