How To Fix Samsung Galaxy S9+ Screen Is Black But Phone Is Working

Problem: I have a Samsung Galaxy S9+.  I was listening to music with my Spotify app.  About 30 minutes later, I am still listening to my music and see blinking lights because messages were coming in, but the screen was black.  I pressed the power button, bixby, volume, they were all working but I couldn’t see anything. I knew they were working because of the phone’s vibrations.  The lights still blink in blue, green and purple (based on notices i have set up). I have tried connecting it to a wall charger, forced restart and recovery mode reboot.  Nothing works and my phone is still receiving messages and calls. Is there anything else I can do before resorting to a factory reset?

Solution: The black screen that you are experiencing with your phone is usually called the Black Screen of Death. This i s an issue where the screen of the phone does not display anything and the phone may or may not be working. To fix this issue you should follow the troubleshooting steps listed below.

Charge the phone

Make sure that the battery of the phone has sufficient charge. Connect the phone to its wall charger for at least 20 minutes. You should see the charging indicator LED light up.

Do a soft reset

Once the battery of the phone has sufficient charge the next step is to perform a soft reset. This is usually performed when the phone is unresponsive or frozen.

  • Press and hold the Power+Volume down buttons until the device powers off (approx. 10 seconds).
  • The Maintenance Boot Mode screen should appear.
  • From the Maintenance Boot Mode screen, select Normal Boot.

Check if you can start the phone in Safe Mode

Sometimes certain apps you downloaded can cause issues on the phone. To check if an app you downloaded is causing the problem you should start the phone in Safe Mode. When the phone operates in this mode only the pre-installed apps are allowed to run. In case the issue does not occur in this mode then it could be caused by an app you downloaded. Find out what app this is and uninstall it.

Do a factory reset in recovery mode

One last troubleshooting step that you can do is a factory reset from the recovery mode. Take note that this will erase your phone data.

  • Turn off the device.
  • 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.

In case the above steps fails to fix the problem then this could already be caused by a faulty hardware component, possibly the display. The best thing to do right now is to bring the phone to a service center and have it checked.
