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.

2. 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.

3. 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.

4. 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.

Interpreting the screen check code for Samsung is essential for taking appropriate action. However, remember that not all screen issues can be fixed through these codes. If you notice any persistent issues, it's always best to contact your phone manufacturer or a repair technician for assistance.
