How to Dark Mode — Samsung One UI
Applies to all Samsung One UI phones and tablets. Menu names may vary slightly by Android version.
Dark Mode on your phone switches the system interface, menus and supported apps to a dark color scheme with light text on dark backgrounds. This significantly reduces eye strain in low light conditions and can extend battery life on AMOLED and OLED displays which consume less power to display dark pixels. It can be enabled instantly or scheduled to activate automatically at sunset.
On your phone: open Settings
Tap 'Display'
Tap 'Dark' to enable instantly
Or: pull down the notification shade and tap the 'Dark mode' quick tile
To schedule: tap 'Dark mode settings' > 'Turn on as scheduled'
Choose Sunset to Sunrise or set a custom time range
Dark mode reduces eye strain and saves battery on AMOLED displays
