Dark Mode changes your iPhone's interface to a dark color scheme, reducing eye strain and saving battery on OLED screens. If it's not working or not switching automatically, here's how to fix it.

✅ Enable Dark Mode

Quick Toggle:

  1. Open Control Center (swipe down from top-right)
  2. Press and hold Brightness slider
  3. Tap Dark Mode button

In Settings:

  1. Settings → Display & Brightness
  2. Under Appearance, tap Dark
⏰ Automatic Switching Not Working?
  1. Settings → Display & Brightness
  2. Enable Automatic
  3. Tap Options
  4. Choose schedule:
    • Sunset to Sunrise — Uses location
    • Custom Schedule — Set specific times

If Sunset/Sunrise Doesn't Work:

  1. Settings → Privacy & Security → Location Services
  2. Scroll to System Services
  3. Enable System Customization
📱 Apps Not Following Dark Mode?

Some apps have their own appearance settings:

  • Check app Settings for "Appearance" or "Theme"
  • Set to "System" or "Automatic" to follow iPhone
  • Some older apps don't support Dark Mode

Common Apps:

  • Safari: Follows system automatically
  • Gmail: Settings → Theme → System default
  • Instagram: Follows system

🔧 Troubleshooting

1. Check Smart Invert

Smart Invert is NOT the same as Dark Mode:

  1. Settings → Accessibility → Display & Text Size
  2. Make sure Smart Invert is OFF
  3. Use actual Dark Mode instead

2. Restart iPhone

  1. Press Side + Volume buttons
  2. Slide to power off
  3. Wait 30 seconds, turn back on

3. Check Date & Time

Automatic scheduling needs correct time:

  1. Settings → General → Date & Time
  2. Enable Set Automatically

4. Update iOS

  1. Settings → General → Software Update
  2. Install any available updates
🎨 Wallpaper Issues

Dark Mode can use different wallpapers:

  1. Settings → Wallpaper
  2. Tap current wallpaper
  3. Some wallpapers have Light/Dark variants
  4. Choose a wallpaper that supports both modes
🔄 Reset Display Settings
  1. Settings → General → Transfer or Reset iPhone
  2. Tap Reset → Reset All Settings
  3. Re-enable Dark Mode after reset

This resets preferences but keeps your data.
