Dark mode on Android has long ceased to be just a fashionable trend - it is a useful feature that reduces eye strain, saves battery power (especially on AMOLED screens) and makes using your smartphone more comfortable in the evening. However, not all users know that activating a dark theme is possible not only through standard settings, but also using hidden parameters or third-party applications for devices where the manufacturer has not provided such an option.

In this article we will analyze all the possible ways to enable dark mode - from basic settings to advanced methods for outdated versions of Android (including Android 8.0 Oreo and below). You will learn how to get the dark theme to work in applications that do not support it, and why this mode may not work correctly on some smartphones. And also - how to automate switching the theme on a schedule, so as not to do it manually every evening.for example, on budget Huawei or Nokia models) this mode may not work correctly. And also - how to automate topic switching on a schedule, so as not to do it manually every evening.

1. Standard method: enable via Android settings

Most modern smartphones Android 10 and newer support dark mode out of the box. To activate it, just follow a few simple steps. Open the menu Settings (gear icon in the notification panel or on the main screen) and follow the instructions:

  • 📱 Go to the section Screen (on some devices - Display or Design).
  • 🌓 Find item Dark theme, Night mode or Color scheme (the name depends on the firmware).
  • ⚙️ Activate the switch. On some smartphones (for example, Samsung Galaxy), you can also configure an automatic turn-on schedule here.

On pure Android (as on Google Pixel or Nexus) the path may be slightly different: Settings → Display → Dark themeIf you have shell from the manufacturer (MIUI, One UI, ColorOS, look for the Additional screen settings or Design style.

📊 What brand of your smartphone?
Samsung
Xiaomi
Google
Huawei
Other

Important: after turning on the dark theme, not all applications will immediately change their design. This depends on whether the specific app supports system dark mode. For example, YouTube, Telegram and Chrome will switch automatically, but some banking applications or games may remain in light mode.

⚠️ Attention: Smartphones with Android 9 Pie and below may not have a standard dark mode. In this case, use the methods in the following sections.

2. Dark theme on older versions of Android (up to 9.0)

If your smartphone is running on Android 8.0 Oreo, 7.0 Nougat or even earlier versions, do not despair - there are several workarounds. The first and simplest is to use "Night Light" mode (aka Night Mode), which, although it does not make the interface completely black, significantly reduces the brightness and blue component of the screen:

  1. Open Settings → Display → Night light.
  2. Activate the function and adjust the filter intensity (recommended 70-80% for maximum effect).
  3. Set a schedule (for example, from 21:00 to 7:00) or turn on the mode manually.

For a full dark theme on old Android devices will need third-party software. The best options:

  • 🔹 Dark Mode for Android (requires ADB to activate hidden functions).
  • 🔹 Night Mode Enabler (works on some firmware without root).
  • 🔹 Substratum Theme Engine (requires root access, but allows maximum customization).
What is ADB and why do you need it?

ADB (Android Debug Bridge) is a tool for debugging Android devices via a computer. It allows you to perform commands that are not available in the standard interface, such as enabling hidden dark theme features. To use ADB, you need to install drivers, enable USB debugging in the developer settings and connect the smartphone to the PC.

On Android 8.0-8.1 you can try to activate the hidden dark theme via ADB. To do this:

adb shell settings put secure ui_night_mode 2

After running this command, reboot the device. If the theme is not applied, it means that your firmware does not support this function.

3. Automatic switching according to schedule or geolocation

Turning on dark mode manually every evening is inconvenient. Luckily, Android allows you to automate this process. Here's how to do it:

  1. Through system settings (available on most smartphones with Android 10+):
    • 🕒 Go to Settings → Display → Dark theme → Schedule.
    • 🌅 Select By schedule and specify the on/off time (for example, from 20:00 to 8:00).
  • Using the application Tasker (for advanced users):
    • 📱 Set Tasker from Google Play.
    • 🔄 Create a task with an action Display → Set Dark Mode.
    • ⏰ Set up a trigger by time, geolocation or light level (via a light sensor).

      • On smartphones Samsung with shell One UI there is an additional option - enable the dark theme by sunset/dawn. To do this, select Sunset to sunrise in the schedule settings - the system will automatically determine the time of day based on your location.

      Enable dark theme in screen settings|Set a schedule (time or sunset/dawn)|Check the operation manually|Set exceptions for individual applications (if necessary)

      -->

      ⚠️ Attention: On In some devices (for example, Xiaomi Redmi Note 8), automatic switching may occur with a delay of up to 10 minutes. This is due to optimization of energy consumption.

      4. Dark theme in certain applications

      Even if you have enabled dark mode on system level, some applications may ignore this setting. Let's look at how to force dark theme activation in popular services:

      Application Path to setting the dark theme Features
      YouTube Profile → Settings → General → Dark theme Works regardless of system settings. There is an option "Follow device settings."
      Telegram Settings → Appearance → Dark Supports 5 dark theme options, including AMOLED Black.
      Chrome ⋮ → Settings → Themes → Dark Dark theme is hidden in experimental functions. An alternative is a browser Kiwi Browser with forced dark mode.
      Instagram Follows system settings There is no separate switch. If it doesn’t work, update. application.
      WhatsApp ⋮ → Settings → Themes → Dark The dark theme appeared in 2020. It is not available on older versions of the application.

      For applications that do not support dark mode (for example, some banking clients or old games), you can use forced dimming via Developer Options:

      1. Activate Settings for developers (click on Build number in Settings → About phone).
      2. Return to main settings and open System → For developers.
      3. Find the option Override force-dark (or Force dark mode) and enable it.

    Force dark mode may break the layout in some applications, rendering text unreadable or hiding interface elements. Before use, check the operation in each application separately.

    5. Dark theme on smartphones of specific brands

    Manufacturers often modify Android to suit their needs, so the process for enabling the dark theme may vary. Let's look at the features for popular brands:

    Samsung (One UI)

    On devices Samsung Galaxy the dark theme is called Dark mode and is located in Settings → Display. Here you can:

    • 🌙 Enable the mode manually or according to a schedule.
    • 📱 Apply a dark theme to Always On Display (if supported).
    • 🔄 Configure exceptions for individual applications (for example, leave Galaxy Store in light mode).

    Xiaomi (MIUI)

    In MIUI 12/13/14 the dark theme is activated via Settings → Display → Dark theme. Features: Settings → Display → Dark theme batteries.

    • 🎨 There is an option Super Wallpaper with dynamic dark theme.
    • 🔄 You can set up automatic switching based on time or battery level.
    • ⚠️ On some models (Redmi 9A), the dark theme is unstable due to performance optimization.

    Huawei (EMUI)

    On smartphones Huawei i Honor the path is as follows: Settings → Screen and brightness → Dark theme. In the latest versions EMUI a function has appeared Smart Dark Modethat analyzes lighting and automatically adjusts the interface.

    💡

    On smartphones Huawei c EMUI 10+ you can enable dark theme for Always On Displayeven if this option is hidden. To do this, use the search in the settings for "AOD".

    Google Pixel

    On Pixel s pure Android the dark theme is maximally integrated into the system. There is a unique feature here - Adaptive batterywhich automatically turns on dark mode when the battery level is low to save energy.

    ⚠️ Attention: On some budget models (for example, Nokia 2.4) dark theme may not be available even Android 11 due to manufacturer restrictions. In this case, only installing custom firmware or using ADB.

    6 will help. Problems with the dark theme and their solutions

    Sometimes, after turning on the dark mode, users encounter bugs: incorrect display of elements, “broken” colors, or spontaneous shutdown. Here are the most common problems and how to fix them:

    • 🔄 Dark theme turns off by itself:

      Check your battery settings - some power saving modes (for example, "Ultra Mode" on Xiaomi) may turn off background processes responsible for the dark theme. Add the application System UI to the optimization exceptions.

    • 🖼️ In some applications, text becomes invisible:

      This is a consequence of the forced dark mode (Override force-dark). Disable it in Settings for developers or add the problematic application to exceptions.

    • 📱 The dark theme does not apply to all menus:

      On some firmware (for example, ColorOS on Oppo/Realme) the dark theme does not affect the system dialogues. The solution is to update the software or use the ADBcommand to force it on:

      adb shell cmd uimode night yes
    • 🔋 Quick battery drain in dark mode:

      Paradoxically, but on some devices (for example, with LCD screens) dark theme may increase power consumption due to additional graphics processing. In this case, it is better to use Night light instead of a full dark theme.

    If none of the methods helped, try resetting the screen settings to standard: Settings → System → Reset settings → Reset display settings. This will return all display settings to factory settings, but will not affect personal data.

    💡

    Before resetting your screen settings, take screenshots of your current brightness settings, color profile, and dark theme schedule to quickly restore them after the reset.

    7. Alternative methods: custom firmware and launchers

    If your smartphone does not support a dark theme at the software level, radical methods remain - installation custom firmware or use alternative launcher. Let's consider both options:

    Custom firmware (requires unlocking the bootloader)

    Firmware like LineageOS, Pixel Experience or Havoc-OS offer advanced dark theme settings, including:

    • 🎨 Selecting accent colors for dark mode.
    • 🔄 Automatic switching based on light sensor.
    • 📱 Support dark theme for Quick Settings i Notification Panel.

    Cons: installation requires unlocking the bootloader, which can lead to loss of warranty and potential security issues.

    Launchers with dark theme support

    A safer way is to install an alternative launcher. Best options:

    • 🏆 Nova Launcher (paid version supports dark theme for icons and menus).
    • 🌙 Lawnchair (free, open source and built-in dark theme).
    • 🎭 Action Launcher (allows you to customize dark mode for individual interface elements).

    Launchers do not change the dark theme at the system level, but can significantly improve the appearance of the main screen and application menu.

    For maximum effect, combine the launcher with dark wallpapers i icons. There are icon packs with support for dark mode, for example, Google Play There are icon packs with dark mode support, for example, Dark Pixel Icons or Moonshine Icon Pack.

    8. Dark mode and health: myths and reality

    Many users turn on dark mode, believing that it reduces eye strain and improves sleep. However, not everything is so simple. Let's take a look at what science says:

    • 👁️ Reducing eye fatigue:

      Studies show that dark mode actually reduces Digital eye strain (Computer Vision Syndrome) when using a smartphone for a long time in the dark. However, during the daytime, a light theme may even be preferable - it contrasts better with the surrounding light.

    • 💤 Effect on sleep:

      Dark mode reduces the amount Blue lightthat suppresses melatonin production (sleep hormone). But for the real effect, it is better to combine it with the mode Night light (it filters the blue spectrum even in a light theme).

    • 🔋 Battery saving:

      On smartphones With AMOLED screens (for example, Samsung Galaxy S23 or Google Pixel 7) a dark theme can extend battery life by 10-30%, since black pixels are not backlit. On LCD screens (for example, on iPhone SE 2020 or Xiaomi Redmi 9) savings are minimal.

    Interesting fact: in 2022, researchers from University of Toronto found that dark mode with gray background (rather than pure black) is less straining on the eyes than the classic light theme, but does not reduce contrast as much as the full AMOLED Black.

    ⚠️ Attention: If you use dark mode due to vision problems, pay attention to specialized applications like f.lux or Twilight. They not only darken the screen, but also adjust the color temperature depending on the time of day.

    FAQ: Frequently asked questions about the dark theme on Android

    Is it possible to enable the dark theme on Android 7.0 without root?

    Yes, but with limitations. You can use:

    • Mode Night light (reduces blue color, but does not make the interface black).
    • Applications like Dark Mode for Android (requires connection via ADB, but does not need root).
    • Dark launchers and wallpapers for visual effect.

    A full dark theme without root is only possible on some firmware (for example, MIUI 12+ on older devices Xiaomi).

    Why in some Dark theme does not work in applications?

    It depends on the application developer. If the application does not support dynamic color scheme (DayNight in Android, it will ignore the system settings. Solutions:

    • Update the application to the latest version.
    • Check the settings inside the application (sometimes the dark theme is hidden in Settings → Appearance).
    • Use Override force-dark in Settings for developers (but this may break the layout).
    How to make system dialogs and menus dark?

    On most smartphones, system dialogs (for example, confirmation windows or notifications) follow the dark theme automatically. If this does not happen:

    1. Check whether the dark theme is enabled in Settings → Applications → Accessibility → Color inversion (not to be confused with a full dark theme!).
    2. On some firmware (ColorOS, FunTouch OS) system menus do not support dark theme. The solution is to install custom firmware.
    3. For Google Pixel and Android One run the command via ADB: 
      adb shell settings put secure ui_night_mode 2
    Dark theme drains the battery faster. Why?

    This is possible in two cases:

    • You LCD screenwhere the dark theme does not save energy, but on the contrary, requires additional graphics processing.
    • Enabled Override force-darkwhich forces the system to constantly redraw the application interface.

    Solution: disable forced dark mode and use the standard dark theme only on AMOLED screens.

    Is it possible to configure different themes for different applications?

    Yes, but not on all devices. Options:

    • On Samsung One UI: Settings → Display → Dark theme → Advanced → Application exceptions.
    • On MIUI: use Second Spaceto create separate profile with a different theme.
    • Universal method: application Tasker with a plugin AutoInput to automatically switch themes depending on the open application.
