Galaxy S21/22/23 Screen change From Pure Black to Greyish/Ashy Tones

Keep in mind, not every fix requires professional help. So, be ready to roll up your sleeves and get into the heart of your Galaxy device. Let’s bring back the deep, pure black that you crave.

Why Does the Galaxy S21/22/23 Screen Change from Pure Black to Greyish Tones?

1. OLED Screen Technology:

The Galaxy S21/22/23 models feature Organic Light Emitting Diode (OLED) screen technology. While this technology offers excellent image quality and deep blacks, it sometimes inadvertently turns black tones to ashy or greyish hues due to its operational characteristics.

2. Software Glitches:

The Galaxy series runs on intricate software. In certain cases, software glitches can alter colour representation on the screen. These glitches can stem from an unstable update or a faulty app installation, causing the screen to display ashy or greyish tones instead of pure black.

3. Third-Party Apps:

Certain third-party apps could interfere with the device’s display settings. An app with poorly optimised graphics or colour coding might lead to inconsistencies in colour representation on the screen.

4. Display Settings:

Incorrect display settings can also cause the screen colour to shift. Sometimes, inadvertently altering a setting can lead to an ashy appearance instead of a pure black tone.

5. Screen Degradation:

Over time, the OLED screen may naturally degrade, causing a shift in the colour representation. This is a common issue in older devices, where the display gradually loses its ability to portray pure black, resulting in greyish or ashy tones.

How to Fix Galaxy S 21/22/23 Screen change From Pure Black to Greyish/Ashy Tones?

Fix 1: Adjust Screen Calibration

  • Step 1: Access Display Settings: Firstly, unlock your Galaxy device. Once on the home screen, navigate to the settings menu. In the settings menu, find and select ‘Display’.
  • Step 2: Choose Screen Mode: Within the ‘Display’ section, find the option named ‘Screen Mode’. This option allows you to adjust your display’s colour balance and temperature. Tap on ‘Screen Mode’.
  • Step 3: Select Your Preferred Mode: Here, you’ll see several options. ‘Vivid’ will give you brighter, more saturated colours, while ‘Natural’ will provide a more realistic colour representation. ‘AMOLED cinema’ offers a vibrant colour experience, and ‘AMOLED photo’ will give you more natural colours. Choose the one that suits your preference.
  • Step 4: Adjust White Balance: In the same ‘Screen Mode’ menu, you can adjust the ‘White Balance’ if you’re not satisfied with the colour temperature. Here, you can manually adjust the levels of ‘Red’, ‘Green’, and ‘Blue’ to achieve the desired effect.
  • Step 5: Confirm and Exit: After making these adjustments, confirm your choices. The changes should take effect immediately. Navigate away from the settings menu, and you should notice a difference in your display’s colour representation.

Remember, adjusting screen calibration is a trial and error process. Don’t hesitate to return to these settings and tweak them until you achieve the desired display colour. This process should help return your display from a greyish/ashy tone back to a rich, deep black.

Fix 2: Perform Software Updates

  • Step 1: Connect to Wi-Fi: For this procedure, it’s best to connect your device to a Wi-Fi network. Software updates can use up a significant amount of data, so make sure you’re connected to a reliable network.

  • Step 3: Check for Updates: Inside the ‘Software update’ menu, select ‘Download and install’. Your device will check Samsung’s servers for any new updates. If there’s an update available, it will show up on this screen.
  • Step 4: Download and Install Updates: If an update is available, select ‘Download’. After the download is complete, the option to install the update will appear. Select ‘Install’ to begin the update process. Remember, your device may need to restart during this process.
  • Step 5: Confirm Installation and Restart: After the update is installed, your device will restart. Post the reboot, your Galaxy S21/22/23 should be running the latest software. This update may include fixes for screen colour representation, potentially resolving the greyish or ashy tone issue.

  • Step 4: Observe for Changes: Now, monitor your device’s screen over the next few hours or days. Look to see if the pure black colour has returned or if the greyish/ashy tones persist.
  • Step 5: Repeat if Necessary: If the problem remains, repeat the process with other recent applications. Continue this process until the issue is resolved.

By keeping a watchful eye on the applications you install, you can ensure the integrity of your device’s display settings. Always remember to install trusted applications to avoid such issues.

Fix 4: Conducting a Factory Reset

  • Step 1: Backup your Data: Before conducting a factory reset, ensure you’ve backed up all your important data. This includes photos, videos, documents, and other files. Use Samsung Cloud, Google Drive, or any other preferred backup service.
  • Step 2: Access the Reset Menu: On your device, navigate to the ‘Settings’ menu. Scroll down and select ‘General management’. From there, find and select ‘Reset’.
  • Step 3: Select Factory Data Reset: In the ‘Reset’ menu, you’ll see several options. Select ‘Factory data reset’. This option will erase everything on your device and restore it to factory settings.
  • Step 4: Confirm the Factory Reset: After selecting ‘Factory data reset’, your device will display a warning, letting you know that all data will be erased. If you’ve backed up your data and are ready to proceed, select ‘Reset’ and then ‘Delete All’.
  • Step 5: Restart and Set Up Your Device: Your device will now restart. After the reset, you’ll need to set up your device as if it were new. Follow the on-screen instructions to get started.

A factory reset is a more drastic measure, but it can often fix persistent issues, such as the screen changing from pure black to greyish or ashy tones. However, remember to always backup your data before proceeding with this step.
