How To Fix Samsung Galaxy A9 Black Screen of Death BSoD

Problem: Hello, I bought the Samsung galaxy A9 5 days ago, the phone is in very good condition, it has no scratches. Now the screen is going black every day , the phone is working but the screen is not responding to the touch and stay black. The screen returns when I’m doing a hard reset. I don’t think it is good to make that many hard resets to the phone.  This problem repeats every day, I took the phone to the lab but they didn’t fix it. Any idea what can cause the problem and how I can fix it? Best regards.

Solution: Before performing any troubleshooting steps on this device you should first make sure that the phone is running on the latest software version. If an update is available then I suggest that you download and install it.

If this is a new phone then chances are it is still under warranty and you can have it replaced with another unit. However, before bringing the phone back to the store you should perform the troubleshooting steps listed below as this could just be caused by a minor software glitch.

Perform a soft reset

A soft reset is usually done when the phone is unresponsive as this procedure will refresh the phone software. to do this just hold the power button and the volume-down button for around 10 seconds. Let go of the buttons once you feel the device vibrate and see the Samsung Galaxy A9 logo on the screen. Your phone will then reboot, and hopefully, start working properly once again.

Start the phone in Safe Mode

There are instances when an app you downloaded can cause this particular problem. The best way to check if an app is causing the problem is to start the phone in Safe Mode since only the pre-installed apps are allowed to run in this mode.

  • Turn the phone Off
  • Press and hold “Power”
  • At the “Samsung” logo, release “Power” and immediately press and hold “Volume down”
  • After the phone finishes rebooting, release the keys. A “Safe Mode” watermark should be visible in the lower area of the home screen

If the screen does not turn black and becomes unresponsive in this mode then you should find out what app is causing the problem and uninstall it.

Wipe the cache partition of the phone

The phone will usually store cached data of apps in a special partition on the internal storage. This cached data allows the phone to open apps quickly however there are instances when the saved data can become corrupted which can cause issues on the device. To eliminate this factor you will need to wipe the cache partition of the phone.

  • Turn the phone Off if necessary
  • Press and hold “Power” “Volume down” and “Home”/”Bixby” at the same time
  • At the Android screen, release the buttons and wait for access to Android Recovery
  • Press “Volume down” to navigate the menu to highlight “Wipe cache partition”
  • Press “Power” to select the highlight
  • Finally, highlight “Reboot system now” and press “Power”

Perform a factory reset

One last troubleshooting step that you should consider doing is a factory reset. This reverts your phone to its original factory condition. Make sure to backup your phone data before doing this step as it will be deleted in the process.

  • 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 above steps fails to fix the problem then the problem is most likely caused by a faulty hardware component. Since this is a newly bought phone I recommend that you bring this back to the store where you bought it from and have it replaced.
