How To Fix Samsung Galaxy Note 9 Screen Is Completely Green

Problem: Hi there, I have an issue regarding my Samsung Galaxy Note 9. It started last month when the screen flickered then turned to green completely. I did a hard reset since I couldn’t see anything on my screen but still, it didn’t fix the issue. I went to the Samsung Service Center but was immediately told that because there’s a crack (which I already had a few months back), I’ll be needing to pay a huge amount to fix it. I want to know if there’s anything else I can do to fix the problem before paying for repair.

Solution: From the way you described the problem it already looks like this is caused by a faulty hardware component. There are however some troubleshooting steps that you can perform to eliminate any software related glitches that could be causing this issue.

Perform a soft reset

Restarting the phone will refresh the software and will usually fix minor phone glitches.

  • Press and hold the volume down button and don’t release it.
  • Now press and hold the Power key while holding down the volume down button.
  • Keep both keys held down together for 10 seconds or more.

Once the phone boots up check if the issue still occurs.

Start the phone in Safe Mode

There are instances when third party apps can cause display related issues. To check if an app you downloaded is causing the problem you will have to start the phone in Safe Mode as only the pre-installed apps are allowed to run in this mode.

  • Turn the device off.
  • Press and hold the Power key past the model name screen appearing on the screen.
  • When SAMSUNG appears on the screen, release the Power key.
  • Immediately after releasing the Power key, press and hold the Volume down key.
  • Continue to hold the Volume down key until the device finishes restarting.
  • When Safe mode appears in the bottom left corner of the screen, release the Volume down key.

In case the display works in this mode then it is most likely caused by an app you installed. Find out what app this is and uninstall it.

Wipe the cache partition of the phone

Your phone will usually store cached data in a designated storage area. This cached data allows the device to work smoothly as it allows for the easy retrieval of the most commonly used phone data. Sometimes though this data can be corrupted which can cause issues with the phone. To eliminate this possibility you will need to wipe the cache partition of the phone.

  • Turn off the phone.
  • Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  • When the Android logo displays, release all three keys.
  • An ‘Installing system update’ message will show for 30 – 60 seconds before the Android system recovery menu options appear.
  • Press the Volume down key several times to highlight wipe cache partition.
  • Press Power key to select.
  • Press the Volume down key to highlight yes, them and press the Power key to select.
  • When the wipe cache partition is complete, Reboot system now is highlighted.
  • Press the Power key to restart the device.

Perform a factory reset

One last troubleshooting step that you should do is  factory reset. This will revert your phone back to its original factory condition. Take note that this step will delete your phone data.

  • Turn off the phone.
  • Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  • When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  • Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  • Press Power button to select.
  • Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  • Press Power button to select and start the master reset.
  • When the master reset is complete, ‘Reboot system now’ is highlighted.
  • Press the Power key to restart the device.

If the issue still persists at this point then this is definitely a hardware related problem most likely caused by a faulty display assembly. If this is the case then a display replacement is the only solution right now. You should bring this phone to a service center so as to get to know the exact amount you will have to play to have this fixed.
