How to Turn on Dark Mode in Samsung One UI

Dark Mode (or Night Mode) isn’t just about aesthetics. For Samsung Galaxy users, it offers real benefits:

  • Reduces Eye Strain in low-light conditions
  • Saves Battery on AMOLED screens
  • Looks Sleek and modern

Samsung One UI makes enabling Dark Mode simple. Here are two easy ways to turn it on:

Method 1: Quick Settings Panel (Fastest)

  1. Swipe down from the top of your screen to open the notification panel.
  2. Swipe again to expand the Quick Settings Panel.
  3. Find and tap the Dark mode icon (crescent moon or half-filled circle).
    • If it’s not visible, swipe left/right or edit your quick toggles.

Your system UI, notifications, and compatible apps will now display in Dark Mode.

Method 2: Display Settings (With Scheduling)

  1. Open Settings > Display.
  2. Tap Dark to enable Dark Mode.
  3. Tap Dark mode settings to schedule it:
    • Turn on as scheduled: Toggle on.
    • Sunset to sunrise: Automatically adjusts based on your location.
    • Custom schedule: Set specific start/end times.

Extra Dark Mode Options (in Settings > Display > Dark Mode Settings)

  • Apply to wallpaper: Dim wallpaper to match dark theme.
  • Adaptive color filter: Reduces eye strain by adjusting screen tone.

What Changes in Dark Mode?

  • System UI: Settings, notifications, app drawer all use dark backgrounds.
  • Samsung Apps: Phone, Messages, Internet, Notes, etc., follow dark theme.
  • Third-Party Apps: Many (like Instagram, Gmail, Twitter) support system-wide dark mode.
  • Wallpaper: May dim if enabled in settings.
