Is your LG V20 experiencing touch screen unresponsiveness? Don’t panic just yet! Before considering a screen replacement, there are a few troubleshooting steps you can take to resolve the issue. In this comprehensive guide, we will walk you through the process of fixing touch screen unresponsiveness on the LG V20. From testing your device to potential solutions, we’ve got you covered.Common Causes of Touch Screen Unresponsiveness

Software Glitches: Sometimes, the touch screen may become unresponsive due to software bugs or conflicts. These issues can arise from outdated software, incompatible apps, or corrupted system files.

  1. Physical Damage: Drops or impacts can cause damage to the touch screen, resulting in unresponsiveness. Cracks or fractures on the display can disrupt the touch functionality.
  2. Water Damage: Exposure to moisture or water can affect the touch screen’s capacitive sensors, causing them to malfunction or become unresponsive.
  3. Hardware Issues: Faulty hardware components, such as a damaged digitizer or loose connections, can lead to touch screen problems. These issues often require professional repairs or component replacements.

Testing Your LG V20

Using the Service Menu

  1. Turn on your LG V20 and access the home screen.
  2. Open the Phone app and enter the code *#0*#.
  3. The Service Menu will appear, displaying various test tiles in the shape of an “X.”
  4. Try touching each tile with your finger. If your touch registers accurately on all tiles, the touch screen is functioning correctly.
