Switching your smartphone display to black and white mode is not just an aesthetic experiment, but a powerful tool for digital detoxification and saving battery power. The bright, rich colors of the interface are specially designed by marketers and psychologists to stimulate the production of dopamine, forcing us to endlessly scroll through our social media feeds. When you remove the color, content appeal drops sharply, and the phone turns from an entertainment center into a utilitarian tool, which helps reduce screen time.
The process of activating the "Grayscale" mode on devices running Android may vary depending on the shell manufacturer and operating system version. In some cases, this feature is available in standard accessibility settings, in others it requires the use of hidden developer menus or third-party applications. Understanding how to make a colorless screen on Androidgives you complete control over the visual perception of the device and allows you to adapt it to your needs without obtaining root access.
Standard settings for accessibility and digital well-being
Modern versions of the operating system, starting from Android 9 Pie and higher, implement time management functions directly into the system core. For most users, the path to activating monochrome mode is through the menu Digital well-being and parental controls. This section was created specifically to combat digital addiction and offers flexible visual settings.
Within this menu, you can often find the “Sleep Mode” or “Rest Time” function, which automatically switches the screen to black and white mode at specified hours. However, many users do not know that in some shells, for example in One UI ot Samsung or ColorOS ot Oppo, you can enable this mode permanently. You need to go to the settings, find the accessibility section and look for items related to improving visibility or color correction.
⚠️ Attention: The settings menu interface may differ on smartphones of different brands. If you do not find the “Grayscale” item in the specified location, try using the settings search by entering the query “color” or “monochrome.”
Activation through standard settings is the most secure method, since it does not require intervention in system files. Once enabled, you will notice that all icons, photos and videos are displayed in grayscale. This may seem unusual in the first minutes, but it is this discomfort that helps the brain stop perceiving the smartphone as a source of entertainment.
Using the developer menu to globally change color
If the standard settings of your device do not provide the ability to permanently enable black and white mode, you can use the hidden menu for developers. This method is universal for most devices based on clean Android and custom firmware. Activating the developer menu requires performing a certain sequence of actions in the “About phone” section.
First, you need to go to Settings → About phone and find the “Build number” item. By clicking on it 7 times in a row, you activate developer mode. After this, a new section will appear in the main settings menu For developers. Inside this section you should find the option “Simulate anomaly” or “Simulate space with color vision deficiencies”.
- 🔘 Select the option "Monochrome mode" or "Full deuteranomaly" to achieve the effect of full discoloration.
- 🔘 Make sure the switch is active and check the changes on the main screen.
- 🔘 If necessary, reset the settings by selecting "Disabled" in the same menu.
Using color vision anomaly simulation is a technical trick that forces the system to render the entire interface in one channel. This solution works at the GPU level, so it applies to all applications without exception.
If you plan to frequently switch between color and black and white mode, add the Developer Mode tile to the Quick Settings panel for instant access.
Third-party applications for filtering the color spectrum
When system settings are limited by the manufacturer; applications from the store come to the rescue. There are many utilities that apply a translucent filter over the entire interface, effectively removing color saturation. Applications such as Google Play. There are many utilities that apply a translucent filter over the entire interface, effectively removing color saturation. Applications like Grayscale Mode or Drearywork without the need to obtain superuser rights.
The principle of operation of such apps is based on creating a special layer on top of all windows. After installing the application, you will need to grant permission to display on top of other windows. This is a critically important stage, since without this right the filter will not be able to influence the system interface and third-party apps.
| Application name | Type of work | Resource consumption | Presence of advertising |
|---|---|---|---|
| Grayscale Mode | System filter | Low | Available in the free version |
| Dreary | Layer overlay | Medium | Absent |
| Night Shift | Temperature correction | Minimal | Partially |
The main disadvantage of using third-party filters is the increased consumption of RAM and battery power, since the filtering process occurs in real time. In addition, some games or applications with anti-aliasing protection may not work correctly when the filter is active. However, for ordinary tasks of surfing the Internet, this method remains one of the simplest.
Why may games not work with a filter?
Many online games use anti-cheat systems that block applications that draw on top of the game window. This is considered a potential vulnerability, so when you start the game, the filter may be automatically disabled or cause the application to crash.
ADB commands for advanced users
For those who prefer full control over the system and do not want to install unnecessary applications, the ideal solution would be to use debugging software USB and console ADB (Android Debug Bridge). This method allows you to change the system color setting directly, without using a GUI or background services. You will need a computer with drivers and platform tools installed.
Connect your smartphone to the computer via a USB cable and make sure that USB debugging is enabled on the device. Open a command prompt or terminal on your computer and enter a command to test the connection. If the device is detected correctly, you can proceed to enter a command that changes the global color simulation parameter.
adb shell settings put secure accessibility_display_daltonizer 1
adb shell settings put secure accessibility_display_daltonizer_enabled 1
The first command sets the simulation type (where 1 corresponds to monochrome mode), and the second activates it. To get the colors back, you need to change the value to 0 or remove the parameter. This method is the most “clean” from the system point of view, since it does not create additional processes in the background.
⚠️ Attention: Using ADB commands requires caution. Entering incorrect commands may cause the interface to become unstable. Always double-check the syntax before pressing the Enter key.
☑️ Preparing to work with ADB
The influence of monochrome mode on the battery and OLED screens
There is a widespread belief that black and white mode saves significantly battery charge, especially on screens like AMOLED and OLED. Indeed, on such displays, each pixel is individually illuminated, and displaying black requires minimal power consumption, since the pixels are simply turned off. However, switching to grayscale mode does not mean that all pixels will turn black.
In grayscale mode, pixels display different shades of gray, from deep black to bright white. White color on OLED screens consumes the maximum amount of energy, since all three subpixels (red, green, blue) are used at full power. Therefore, if your interface contains a lot of white background, there will be little or no battery savings.
However, indirect savings do occur. When the screen becomes less attractive, the user spends less time in flashy applications, such as Instagram or TikTokwhere video content predominates. Reducing active screen time is the main factor in extending device battery life throughout the day.
Black and white mode itself does not turn off the pixel backlight completely, so you shouldn’t expect a miraculous increase in battery life on a single charge if you continue to actively use your smartphone.
Psychological aspects and digital hygiene
The main purpose of switching the screen to a colorless mode is to change user behavior patterns. Research shows that bright red notifications and colorful icons act as triggers that make you want to check your phone immediately. By removing color, we deprive the brain of these visual anchors, making interaction with the device more conscious and less impulsive.
Many users note that after turning on the monochrome mode, they are less likely to unlock the phone automatically. The smartphone becomes boring, and the desire to scroll through the news feed just disappears. This allows you to focus on the tasks that really matter and reduces the stress associated with a constant flow of information.
However, it is worth considering that for some activities, such as viewing photos, navigating maps or working with graphics, the lack of color can be a significant inconvenience. In such situations, it is recommended to use automatic scripts that turn on black and white mode only at certain times of the day or when launching specific applications.
Is it possible to make only a specific application black and white?
This cannot be done using standard Android tools; the mode is applied to the entire system globally. However, some third-party filter applications allow you to create profiles that are activated only when you launch selected apps, although this may work unstable on new versions of the OS.
Does the grayscale mode affect the quality of the camera's shooting?
No, the display setting only affects the display of the image on the screen of your smartphone. Photos and videos taken by the camera are saved in full color and will be displayed normally on other devices or after turning off the mode.
Why did the option to enable monochrome mode disappear after updating Android?
Shell manufacturers often change the location of settings or remove certain functions to suit the new design. In this case, it is recommended to check the developer menu or use third-party applications from Google Play that emulate this feature.
Will Reading Mode work in black and white?
Yes, Reading Mode (usually making the background yellow or warm) may conflict with grayscale filters. It is better to choose one thing: either a warm color temperature to protect the eyes in the evening, or complete bleaching to reduce dopamine dependence.
