As we all know, there are some common problems on smartphone screens such as screen bleeding, burn-in, dead pixels, and ghost touch.
To avoid getting a device with such screen defects, you should recognize the symptoms from the beginning of buying a phone by looking carefully at the entire screen surface. Usually this problem will be easy to find if using a wallpaper with one color.
If there are dead pixels on the screen, you will see small black or white dots in certain areas. Well, to make it easier for you to find screen damage, Samsung equips its smartphones with a Diagnostic feature to test the screen for dead pixels or other problems.
Using the Screen Check Code
First, we will teach you how to test the Samsung A34 touchscreen using a code. Here are the steps.
- Tap the Phone icon on the Samsung home screen.
- Then enter the code *#*#88#*#*.
- Next will be taken to the Item Test menu.
- On this hardware testing page there are various options.
- Select Touchpanel Edge to check the condition of the touchscreen.
- After that, a red line will appear on your phone screen.
- Place your finger on the red line, then move your finger following the line pattern.
- If you pass the test, a check mark will appear on Touchpanel.
Using Samsung Members
For the second method, we will use a built-in app called Samsung Members. You can test the health of your screen through this app. Here’s how to test it.
- Open your Samsung A34, then run the Samsung Members app.
- Then tap the Support tab.
- In the Diagnostics section, tap View Tests.
- Several hardware testing options will be displayed, select Touch Screen.
- After that, the screen will be filled with a checkered pattern.
- Tap all the squares until they turn blue to run the test.
If all the boxes can change color to blue, the screen is still normal.
LCD Test

- Open the Phone app on the Samsung A34 phone.
- Then dial *#*#88#*#*.
- After that it will enter the Item Test page.
- Select LCM to test the condition of the LCD.
- After that, the screen will be entirely red.
- You should test each area for black dots or white dots and also whether there are certain areas where the color is slightly different. So, make sure the colors displayed on the screen are even and there are no spots.
- If so, tap the screen and then switch to another color and so on.
- If during the test you don’t find any problems as we mentioned earlier, when the notification appears “Is LCM test pass?” select Pass.
We recommend regularly checking the screen at least once every 3 months so that you can quickly find out the appearance of screen damage such as dead pixels or burn.
