How to troubleshoot your Galaxy A5 suffering from the black screen of death

Problem: Hi guys. I have a problem with my Galaxy A5, it won’t turn on anymore but there’s this blue light flashing at the top of the display. I’m not quite sure if the phone is really on or off but it just won’t respond when I try to power it on. It started yesterday I think because I noticed that it was very slow when I use facebook and an hour later when I took it out of my pocket, the screen won’t power on. It stayed like this since then. What can I do about it? Thanks in advance.

Troubleshooting: There is only so much we can do about a phone that won’t respond or power on but as a user, you have to do something to try to bring the phone back to life because if the problem happened without apparent reason, it’s more likely a minor one. Doing some troubleshooting procedures might save you from the hassle of going to the shop and explaining to the tech what happened to your device.

I drafted a few steps you can try below. Try to go through each of those steps as one of them may be able to solve this problem.

Step 1: Do the Forced Reboot procedure

In the event wherein the system crashes, the phone may become unresponsive. In fact, it’s one of the most common reasons why the black screen of death occurs in the first place. When the system crashes, the device may no longer respond when you press the Power key nor will it detect electric current when you connect it to a charger. Fortunately though, a system crash can be fixed by doing the battery pull procedure but in this case wherein the phone doesn’t have a user-removable battery, you can do the forced reboot procedure which does the simulated battery disconnect; just press and hold the Volume Down and the Power keys together for 10 seconds.

Assuming the problem is caused by a crash, then the phone may reboot without any issues and that might be the end of the problem and you may not have to go through all the steps below. So, do this step first and then proceed if the problem remains.

Step 2: Attempt to charge the phone

After doing the first step and your phone is still not responding, it’s possible that its battery already got depleted. Naturally in this case, there’s no way your phone can power on since there’s not enough power to bring it back to life. So, plug the charger to the wall outlet and then connect your phone to it using the original USB cable. If the battery got totally drained, it may take a few minutes for the phone to display the charging icon on the screen or light up the LED at the top of the screen. Regardless whether you see those charging signs or not, allow the phone to charge for 10 minutes and then attempt to power it on normally. If it still won’t respond, then do the forced reboot procedure once again while the phone is still plugged in.

Should this step fail to fix the problem, then you have to move on to the next step as the problem is not as minor as it seems.

Step 3: Try to run the phone in safe mode

After doing the first two steps and the phone still has the black screen of death with blinking blue LED, then it’s time to try to run it in safe mode. All third-party elements will be temporarily disabled in this mode so if the problem is caused by one of them, the phone may successfully start. However, booting your phone in this mode doesn’t actually fix the problem but, at least, you can already rest assured the phone’s hardware is totally fine and that the problem might just be with one of the apps you installed. Here’s how you start your phone up in safe mode:

  1. Turn the device off.
  2. Press and hold the Power key past the screen with the device name.
  3. When ‘SAMSUNG’ appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see ‘Safe Mode’.

Assuming that you’ve successfully started your phone up in safe mode, then it’s obvious one or some of the apps you installed is causing the problem. But since we don’t know for sure which of them is the culprit, try updating those apps that need to be updated…

  1. From any Home screen, tap the Apps icon.
  2. Tap Play Store.
  3. Tap the Menu key and then tap My Apps. To keep your apps automatically updated, tap the Menu key, tap Settings, and then tap Auto-update apps to select the check box.
  4. Choose one of the following options:
    • Tap Update [xx] to update all applications with updates available.
    • Tap an individual application and then tap Update to update a single application.

However, if you suspect an app or two, then I suggest you reset those apps by clearing their caches and data and if that won’t work, try uninstalling them…

How to clear app caches and data on Galaxy A5

  1. From any Home screen, tap the Apps icon.
  2. Tap Settings.
  3. Tap Applications.
  4. Tap Application manager.
  5. Tap the desired application in the default list or tap MORE > Show system apps to display pre-installed apps.
  6. Tap Storage.
  7. Tap Clear data and then tap OK.
  8. Tap Clear cache.

How to uninstall applications from the Galaxy A5

  1. From any Home screen, tap the Apps icon.
  2. Tap Settings.
  3. Tap Applications.
  4. Tap Application manager.
  5. Tap the desired application
  6. Tap Uninstall.
  7. Tap Uninstall again to confirm.

On the other hand, if the phone won’t start in safe mode, then you should try the next step.

Step 4: Try to boot the phone up in Recovery mode

This is your last resort. If the phone won’t boot up in this mode, then it’s time to bring it to a shop and let a tech check it out. However, if you can successfully bring the phone to start in this mode, then there’s a big chance you can get it fixed as you can do a couple of very important procedure that would fix possible firmware-related issues. First you need to try wiping the cache partition so that all corrupt caches will be replaced with new ones. If that won’t work, then you can reset your phone from this mode as well.

How to start Galaxy A5 in Recovery mode and wipe cache partition

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  3. When the device logo screen displays, release only the Power key
  4. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times key to highlight ‘wipe cache partition.’
  6. Press the Power key to select.
  7. Press the Volume down key to highlight ‘yes’ and press the Power key to select.
  8. When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
  9. Press the Power key to restart the device.

How to start Galaxy A5 in recovery mode and do the master reset

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  3. When the device logo screen displays, release only the Power key
  4. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times key to highlight ‘wipe data / factory reset.’
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.

Please note that when you reset your phone, all your files and data saved in the phone’s internal memory will be lost and while you may be hesitant to do this procedure, you actually don’t have much of a choice now but it’s your call if you want to do it or not.
