Adjust Display Settings & Dark Theme
Display settings control brightness, screen timeout, font size, and Dark theme — a system-wide dark color scheme that's easier on the eyes and can save battery on some screens.
How to open Display & Dark Theme
- Open Settings → Display.
- Turn on 'Dark theme' or tap it to set a schedule.
- Adjust brightness, font size, and screen timeout as needed.
What you should know
- Dark theme can be scheduled to turn on automatically at sunset or on a custom schedule.
- Adaptive brightness learns your preferences and adjusts screen brightness automatically.
- Font and display size can be scaled independently for readability.
- Screen timeout controls how long the display stays on before locking.
Very short screen timeouts save battery but can make the screen lock while you're still reading — balance based on your habits.
Why it matters
Display settings shape how comfortable your phone is to use for hours every day, from eye strain in low light to readability of small text. On OLED and AMOLED screens, which most modern Android phones use, Dark theme can also meaningfully reduce power draw since black pixels draw far less energy. Getting brightness, timeout, and theme right is a quality-of-life setting most people only think about after they've been squinting at their screen for months.
Best practices
- Schedule Dark theme to follow sunset-to-sunrise instead of switching it manually every day.
- Use adaptive brightness instead of a fixed level so the screen adjusts automatically across lighting conditions.
- Increase font or display size for readability rather than holding the phone closer to your eyes.
- Set a shorter screen timeout in public and a longer one at home to balance battery life and convenience.
Common problems and fixes
- Some apps don't switch to dark theme even with the system-wide setting on.
- Check that app's own in-app theme toggle, since many require a separate setting, or enable 'Override force-dark' under Developer options for unsupported apps.
- Screen turns off too quickly while reading.
- Increase the duration in Settings → Display → Screen timeout, or use an attention-aware feature (on supported devices) that keeps the screen on while you're looking at it.
- Adaptive brightness doesn't seem to learn your preferences.
- Manually adjust brightness a few times across different lighting to help it calibrate, or turn it off and set brightness manually if it keeps misjudging.
- Dark theme's sunset-to-sunrise schedule doesn't trigger at the expected time.
- Confirm location services are enabled, since that schedule calculates sunset and sunrise based on your location.
Tips and tricks
- Add a Dark theme toggle to Quick Settings for one-swipe access instead of digging into the Display menu.
- Try 'Extra dim', found near brightness controls, for comfortable nighttime reading below the usual minimum brightness.
- Use Bedtime mode in Digital Wellbeing to auto-enable Dark theme and grayscale together at night.
Frequently asked questions
Does dark theme actually save battery?
On OLED/AMOLED screens, which most modern Android phones use, yes — black pixels draw significantly less power; on LCD screens the savings are minimal.
Can dark theme turn on automatically at a specific time I choose?
Yes, pick a custom schedule instead of sunset-to-sunrise under Display → Dark theme settings.
Why does my screen look dim outdoors even at maximum brightness?
Check for a screen protector affecting visibility, and look for a boosted outdoor brightness mode if your device offers one.
Can I set dark theme for only some apps and not others?
Some Android versions allow per-app dark theme overrides under Settings → Apps → [app] → Display, though not every app supports it.

More Display & Sound guides for Android
- NotificationsNotification settings let you decide which apps can alert you, how those alerts look, and where they show up — from the lock screen to the status bar. You can manage this globally or app by app, and choose which notifications are urgent enough to break through Do Not Disturb.
- Sound & VibrationSound & Vibration settings control independent volume levels for media, ringtones, notifications, and alarms, along with vibration intensity and patterns. You can also assign custom ringtones per contact and configure haptic feedback for touch and typing.
- Do Not Disturb / Focus ModeDo Not Disturb silences calls, texts, and notifications while still letting you choose specific exceptions, like starred contacts or repeat callers. Android's broader Modes system extends this with presets like Bedtime and Driving, plus fully custom modes for work or focus time.
- Game Mode / Game DashboardGame Dashboard is an overlay that appears during gameplay on supported devices, offering an FPS counter, screen recording, screenshot capture, and a one-tap Do Not Disturb toggle without leaving the game. Game Mode, accessed from the same overlay, lets you choose between prioritizing performance or battery life for that specific title.
- Font Size & Display SizeFont Size and Display Size sliders scale text and interface elements system-wide, independently of each other, so text can be enlarged for readability while overall layout density stays the same, or the entire UI can be scaled up including icons and spacing.
- Screen TimeoutScreen Timeout controls how many seconds or minutes of inactivity elapse before the display automatically turns off and locks, balancing convenience against battery use and security.
