In an age where smartphones are a pivotal part of our daily lives, issues like a black and white display on your Samsung S21 can be frustrating and perplexing. Imagine scrolling through your favorite apps, taking stunning photos, or watching videos, only to be greeted by a monochromatic screen. In this article, we will explore the reasons behind this occurrence, potential solutions, and tips for ensuring your device’s display remains vibrant and colorful.
Understanding the Samsung S21 Display
The Samsung S21 is known for its stunning Dynamic AMOLED 2X display, offering rich colors and vivid imagery. However, encountering a black and white screen can compromise your experience. Before we dive into troubleshooting, it’s crucial to understand how the display works and what could lead to this issue.
The Basics of AMOLED Technology
AMOLED (Active Matrix Organic Light Emitting Diode) is a display technology that enhances color accuracy and contrast. Each pixel emits its light, allowing for deeper blacks and brighter colors. This technology is a significant contributing factor to the S21’s superior display quality.

- Select Screen Mode and ensure you’re in the Vivid mode.
Switching between different modes can often restore the colorful experience your device is designed to provide.
Accessibility Features
Your Samsung S21 is equipped with various accessibility features aimed at helping users with visual impairments. Sometimes, these features can unintentionally change your display settings, resulting in a black and white screen.

What causes my Samsung S21 to display in black and white?
The black and white display on your Samsung S21 can be attributed to various settings or features that might have been unintentionally activated. One common cause is the “Grayscale” mode, which is designed to help users reduce phone distractions by limiting color use. When this mode is enabled, the entire interface and visuals will only show in shades of gray.
Another reason could be a setting related to accessibility features that may have been turned on. Samsung devices often include options that cater to visual impairments, which could also cause the device to display content only in black and white. Checking your accessibility settings is a good place to start when troubleshooting this issue.
How can I check if Grayscale mode is enabled on my Samsung S21?
To determine if Grayscale mode is active, you can navigate to the “Settings” app on your Samsung S21. Scroll down to find “Accessibility,” then select “Visibility enhancements.” Here, you will find an option for Grayscale. If it is toggled on, simply switch it off to restore your device’s color display.
If you don’t see the Grayscale option under Visibility enhancements, you can also check the “Digital Wellbeing” section in your Settings to confirm whether any modes or settings that limit colors are turned on. Disabling any such settings will generally resolve the black and white display.
Is there a way to disable Grayscale mode quickly?
Yes, there is a quick way to disable Grayscale mode on your Samsung S21. You can do this through the Quick Settings panel. To access it, swipe down from the top of your screen to reveal the Quick Settings menu. Look for an option labeled “Grayscale” or “Color Inversion” and tap on it. If it is activated, this action will turn it off, allowing your device to revert to displaying colors.
In the case that you cannot find these settings in the Quick Settings panel, you may need to add the Grayscale toggle. To do this, tap on the three-dot menu in the top-right corner of the Quick Settings panel, select “Edit buttons,” and drag the Grayscale icon into your Quick Settings for easier access in the future.
Could a software glitch cause my Samsung S21 to show black and white?
Yes, a software glitch can potentially result in your Samsung S21 showing a black and white display. This can occur after a recent software update or installation of a new app that might have altered display settings. Software bugs can lead to unexpected changes in how the device operates, including its color display.
If you suspect a software glitch is the culprit, restarting your device is often a simple but effective solution. A reboot can clear temporary issues and reset the system. If the problem persists, it may be necessary to check for any pending system or app updates, as these can sometimes fix bugs related to display issues.
What should I do if none of the settings are causing the black and white display?
If you’ve checked all relevant settings and the black and white display persists, you may want to consider performing a cache partition wipe. This process removes temporary files that might be causing inconsistencies in how your device performs. To do this, power off your Samsung S21, then press and hold the Volume Up and Power buttons simultaneously until you see the Samsung logo. From the Recovery menu, navigate to “Wipe cache partition” and confirm your selection.
If the issue still continues after this step, a factory reset might be necessary. Keep in mind that this will erase all data from your device, so be sure to back up any important files before proceeding. After doing a factory reset, the device should return to its original settings, which should typically resolve any persistent display issues.
Can hardware issues lead to a black and white screen on my Samsung S21?
While hardware issues are less common compared to software settings causing a black and white display, they can occur. For instance, physical damage to the screen or internal components may result in color distortion or a grayscale effect. If your device has experienced any drops or liquid exposure, it could lead to such hardware-related problems.
In cases where you suspect a hardware issue, it’s advisable to have your device inspected by a professional technician or visit a Samsung service center. They can properly diagnose the problem and determine if repairs or replacements are needed. Ignoring potential hardware issues may lead to further damage over time.
Could third-party apps cause my Samsung S21 to display in black and white?
Yes, certain third-party applications can inadvertently change your device’s display settings, causing it to show in black and white. Some apps designed for visual modifications or screen filters can affect how colors are rendered. Additionally, certain apps that are not optimized for your device may malfunction, leading to a range of display issues, including grayscale screens.
If you suspect that a third-party app is behind the color issue, try booting your device in Safe Mode. This mode disables all third-party applications and can help you identify if one of them is the source of the problem. If the screen displays colors normally in Safe Mode, it indicates that a third-party app requires a closer look or may need to be uninstalled.
