How to troubleshoot Galaxy J5 with black screen of death

Problem: Hi. I just found your website while trying to find a solution to the problem I have with my Galaxy J5. I hope you will help me with my problem because I’m already so worried about this phone as it won’t turn on. I mean the screen is black and the phone won’t turn on when I press the power key. But there’s blue light that keeps blinking as if I have messages I haven’t read. Is my phone still powered on? Why is it that it won’t respond? Help me please. Thanks.

Troubleshooting: You know what, we can only do so much about a phone that won’t respond so there are a few steps in this troubleshooting guide and we’re hoping that one of them could fix this issue. Here’s what you need to do:

Step 1: Remove the battery from your phone

I understand you can see there’s blinking blue light at the top of the screen and the phone might actually still be powered up but the operating system isn’t responding. If you’ve used old computers, it’s basically the same as when the computer hangs and you’re stuck on a screen because it doesn’t respond anymore. What we usually do is unplug the power cord and then plug it back in and turn the computer on.

Since we’re dealing with a phone here, we only have to remove the battery to cut it off from its power source and then we’ll try to start your phone up again. But there’s a little more steps…

  1. Remove the back cover of your phone.
  2. Pull the battery out.
  3. Press and hold the Power key for a minute to drain stored electricity in some components.
  4. Place the battery back in and secure it with the  back cover.
  5. Turn the phone on.

If your phone actually turned on after this, then problem solved. Otherwise, try the next step.

Step 2: Charge your phone for 5 minutes

Let’s just rule out the possibility that the phone won’t turn on due to drained battery. So, connect it to its charger that’s plugged into the wall outlet that works. Leave it charging for 5 minutes regardless whether it responds immediately when you connect it or not. Be mindful, however, of its temperature. If you notice the phone heats up while charging, remove the charger immediately and at this point, don’t continue your troubleshooting. Instead, bring the phone to the shop and let the tech handle the problem for you. It seems like it’s a hardware-related problem.

However, if the phone doesn’t heat up, leave it charging for a few minutes and then attempt to turn it on. If still no, the next step might help.

Step 3: Attempt to start your phone up in Safe mode

This step is used to rule out the possibility that the problem is caused by one or some of the third-party apps you installed. You have to boot your phone in safe mode to temporarily disable all third-party elements so that you can isolate the problem immediately.

  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’.

If you’ve successfully brought your phone up to start in safe mode, then problem solved. At least you can now rest assured the problem isn’t with the hardware. Usually we suggest finding the apps that are causing the problem but that would take forever to finish especially if you already have hundreds of apps in your phone. So, I suggest you just backup your files and data and then reset your phone to fix this problem.

  1. From the Home screen, tap the Apps icon.
  2. Tap Settings.
  3. Tap Backup and reset.
  4. If desired, tap Back up my data to move the slider to ON or OFF.
  5. If desired, tap Restore to move the slider to ON or OFF.
  6. Tap Factory data reset.
  7. Tap Reset device.
  8. If you have screen lock turned on, enter your PIN or password.
  9. Tap Continue.
  10. Tap Delete all.

Step 4: Attempt to start your phone up in Recovery mode

You only have to do this procedure if your phone didn’t boot up in safe mode. When it comes to firmware issues, your phone has a fail-safe that will allow users to actually still do some general troubleshooting procedures. That fail-safe is the Recovery Mode and even if your phone has a serious firmware problem for as long as the the firmware wasn’t tampered or modified, there’s still a chance  you can boot it up in this mode. And if successful, you can try wiping the cache partition and doing the reset.
