Nowadays, smartphones have evolved into an essential aspect of our daily routine. They help us talk to people, keep us entertained, and we can even use them for work. However, with all this usage comes wear and tear, and screen issues can happen.

These issues can range from minor scratches to significant damage that affects your phone's functionality. To save users time and money, Samsung has developed secret codes for screen checks.

So, if you own a Samsung smartphone and are experiencing screen-related issues, worry not! In this article, we will explore these codes to diagnose screen-related problems using the Samsung screen test code.

Part 1. Understanding Samsung Screen Test Codes

Samsung display test codes are hidden codes that allow users to check their phone functionality. These codes are easy to access and can be used to perform various tests to identify smartphone issues, including the screen.

Using these codes can be very helpful because they can help us in several ways. For example, they allow us to detect problems early on, which can prevent them from becoming more severe and costly to fix.

Additionally, they can help us save time and money on repairs. We can use these codes to check if our phone's screen is working properly before anything happens.

Here is a list of Samsung screen test codes:

  • *#0*#- This code allows you to test various components of your phone, including the screen. You can check for dead pixels, color accuracy, and touch sensitivity.
  • *#*#0*#*#* - This is the Samsung LCD test code. You can use it to test the functionality of your device's display (LCD).
  • *#2663#- This is the Samsung touchscreen test code. It gives you access to the Touchscreen Firmware Update menu, which can help fix touchscreen issues.

Try using these codes to ensure that your phone's screen is functioning correctly. With the list of secret codes provided, you can now perform screen checks and keep your phones functioning optimally.

Part 3. Common Issues Detected by Samsung Screen Test Codes

Samsung screen check codes can detect a wide range of screen issues. The most common ones include dead pixels, color accuracy, touch sensitivity, and screen burn-in. If you are unsure about them, we have simplified the information here:

  1. Dead pixels

Dead pixels are areas of the screen that do not display any image. This issue can be caused by physical damage to the screen or a manufacturing defect. To test for dead pixels, use the #0# code and select the "Red," "Green," and "Blue" options. If you notice any black spots, your screen may have dead pixels.

  1. Color accuracy

Color accuracy is another issue that can affect your screen's quality. It can be caused by calibration issues or hardware problems. To test for color accuracy, use the same code and select the "Display" option. From there, you can compare the colors displayed on your screen to the reference colors and adjust the calibration if necessary.

  1. Touch sensitivity

Touch sensitivity issues can cause your screen to be unresponsive or register false touches. When dialing the code, select the "Touch" option and test the touch accuracy and sensitivity by drawing lines and shapes on the screen.

  1. Screen burn-in

Screen burn-in occurs when an image remains on the screen for an extended period. It causes a ghost image to appear even after the image has been removed. To test for screen burn-in, the code will let you select from the "Red," "Green," and "Blue" options. From there, you can check for any ghost images that may be present.
