How To Fix Samsung Galaxy A9 Screen Not Turning On After Drop
Problem: The screen had went black when i dropped it a few weeks ago. It had turned on randomly, after leaving it alone on the charger overnight until the middle of the day. Then was working properly until now; I dropped it a couple times on the face of the screen. Now it is not working again. The screen is black and the lighted buttons on the side of the the home button is working. I can hear the volume buttons working and the sound of me taking a screenshot but nothing else. I don’t know what else to do, because i had tried other methods for example charging it overnight, rebooting the Android, holding the power key button and volume down buttons with the home button but nothing has gotten the screen to turn on.
Solution: It’s very likely that the drop might have damaged the display assembly of the phone which is why the device is still working but you are not able to see anything on the screen. While this already means that you will need to bring the phone to a service center there are still a couple of troubleshooting steps that you can do to eliminate the other factors that can be causing this problem.
Perform a soft reset
A soft reset is usually done when the phone is unresponsive and can also be done when the screen is black as this procedure will refresh the phone software. To perform this step 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 cases when an app you downloaded can cause this particular problem. The best way to check if a third party app is the culprit 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 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 works in this mode then you should find out what app is causing the problem and uninstall it.
Wipe the cache partition of the phone
Your phone will usually store cached data of apps in a special partition in its internal storage. This cached data allows the device to open apps quickly making for a faster Android experience however there are instances when the saved data can become corrupted which can cause issues. 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”
Once this is done check if the issue still occurs.
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 this is most likely caused by a damaged display assembly. I recommend that you bring this to a service center and have it repaired.
