The LCD or touchscreen is one of the most crucial components in a smartphone. If it starts to malfunction, daily activities such as typing, gaming, or watching videos will be disrupted. That’s why it’s important for Vivo users to know how to check their LCD condition to detect issues early.
1. Using Secret Codes
Vivo provides secret codes that can be used to test the hardware. Open the dialer app and enter *558# to access the “Factory Test” menu. Select “Engineering Test” and run the “Handwriting Test” or “Touchscreen Test.” If the screen responds well, the LCD is still in good condition. Another option is *#800#, which offers more comprehensive tests including color checks and touchscreen response.
2. Using Screen Testing Apps
Besides secret codes, users can also take advantage of apps available on the Google Play Store. Apps like Multi Touch Test or Touchscreen Calibration help examine screen sensitivity. These tools can show whether there are unresponsive areas or early signs of damage.
3. Performing a Visual Check
A simple step is to inspect the screen physically. Remove any screen protector or tempered glass, then view the LCD under bright light. Damages may appear as faint lines, dark spots, stains, or small cracks along the edges. Even minor issues like these can worsen over time if ignored.
4. Tips for Checking LCD
For better accuracy, display a full white or full black background while testing. Avoid rushing the process, as the system needs time to register each touch input. If you find any damage, it’s best to replace the screen with high-quality components.
Regularly checking your Vivo LCD will help maintain optimal smartphone performance and prevent more serious damage.
