Turn Night Mode On or Off auf Samsung
Night mode swaps the light interface for a darker color scheme across menus, the notification panel and many system apps. On OLED screens, darker pixels use less power, so battery life improves alongside the reduced eye strain in low light.
Samsung places this setting inside the Display menu rather than hiding it in accessibility options, so it stays easy to find and toggle whenever lighting conditions change.
Where to find Night mode
Go to Open the Settings ➔ Tap on Display ➔ Enable or disable Night mode. From there you can switch it on or off instantly, or set it to run on a schedule so it activates automatically at sunset or during fixed hours.
If you prefer full control over individual app colors instead of a system-wide switch, check whether the app itself offers its own dark theme. Some apps ignore the system setting and need to be adjusted separately.
Night mode changes color only, it does not lower screen brightness. If your device still feels too bright at night, combine it with a lower brightness level or the Blue light filter for a more comfortable display.
