If you are a Galaxy S20 user and have encountered the green and white screen issue, don’t worry. This problem is common with a lot of Galaxy S20 devices.

This is actually caused by a hardware component, which is the display cable (also known as the flex cable/ribbon cable). This cable is responsible for transmitting data from the phone’s processor to the display. If it gets loose or breaks, it can result in a green or white screen.

In this guide, we will walk you through 03 Fixes that you can apply to resolve this problem. Keep reading to find out how.

Note: Solutions in this guide will work on any Samsung Galaxy S20 model (S20, S20 Plus, S20 Fe, and S20 Ultra models.)

Editor’s note: We created these instructions using a Samsung Galaxy S20 running Android 12. Depending on your device’s software version, some steps and menu positions may look slightly different.

Fix 01: Gently Press the Bottom of the Screen

As we said before, the issue with the green or white screen on your Samsung S20 is due to a loose connection in the display cable. 

By gently pressing the bottom of the screen, we are trying to reseat the display connection of the Galaxy S20. Here is how you should do that:

Note: This is a temporary solution and might not work for all devices.

  1. Turn off your Samsung S20. It’s always a good idea to turn off your device before trying any physical manipulations.

Fix 02: Check For Any Visible Physical or Water Damages

Physical damage can cause the display cable to become loose or even break, while water damage can short-circuit the components responsible for the display. 

Did you drop your phone recently? Or did it get wet in the rain, or was it accidentally dropped in water? If so, these could be the reasons why your Galaxy S20 is displaying a green or white screen.

Therefore, inspecting your Galaxy S20 for these damages will help you identify what has caused the issue. 

To check for water damage, you can inspect the LDI (Liquid Damage Indicator) on your device

Here’s how:

  1. Eject the SIM card tray from your Samsung Galaxy S20.
  2. Look into the SIM card slot. You should see a small sticker.
  3. If the sticker is white or has visible x’s, your device has not been exposed to water. However, if the sticker is pink or red, it indicates that your device has been in contact with water.

If you identify the device has been exposed to water, it’s best to take it to a Samsung service center for repair. Please note that Water damage is not typically covered under warranty. So you may have to pay for the repair.

Fix 03: Take the Device to a Repair Center

If the green/white screen issue on your Galaxy S20 continues even after applying the above fixes, you should take your device to a Samsung repair center.

This is because attempting to replace them on your own could cause further damage to your device. 

You can find the nearest Samsung repair centre by following this link: Samsung Service Centre Locator.

Before you take your device for repair, check if it’s still under warranty. If it is, the repair could be done for free or at a reduced cost (conditions may apply).
