How to troubleshoot your Galaxy A7 that no longer powers on

Aside from other possibilities, there are two that often cause this kind of problem; either it’s hardware problem or an issue with the firmware. But then of course, we don’t know why your phone won’t turn on anymore that’s why we need to troubleshoot. Try to read the problem sent by one of our readers below as it describes how this issue occurred…

Problem: Hello. First of all, thank you for fixing my problem a couple of months ago. I was using the Galaxy S6 back then when I encountered the problem and you guys provided me with a solution that actually worked. Thanks for that. Now I need another advice from you since I just got a Galaxy A7 in May and now it seems like it won’t turn on anymore. I mean the screen is black and the phone won’t respond no matter what I do. I already tried charging it thinking it might just be a problem caused low battery but it didn’t charge either. I’m a bit worried about it since the phone is barely a couple of months old and I’ve taken care of it ever since I bought it. Can you guys help me out. Thanks.

Troubleshooting: The purpose of this troubleshooting guide is for us to know if this problem is minor and if we can fix it on our own. There are times when the problem is beyond our league and we have to seek assistance from a technician who can do further tests without voiding the warranty.

Before we begin, please remember that the problem with your phone is that it no longer powers on. So, if we can make it turn on, then problem solved. The thing is, there’s only so much we can do about a phone that won’t power up. So, we can only attempt to do some things just to see if the phone responds. With all that being said, here’s what I suggest you do:

Step 1: Do the soft reset on your Galaxy A7

The first thing I want you to do is Forced Reboot, which is also known as soft reset. It is the same as the battery pull procedure we often do to phones with removable battery but since your A7 has a non-removable battery, then you have to do this.

Press and hold the Volume Down and the Power keys together for 10 seconds and your phone may reboot normally. That is if the problem is caused by a glitch in the system that caused the phone to crash and if the phone still has enough battery left.

If this problem started without apparent reason, this might be the only thing you need to do to bring your phone back to life. However, if the it still won’t respond after this, then move on to the next step.

Step 2: Connect it to the charger and do the soft reset again

Plug your charger to the wall outlet that you know works and then connect your phone. I understand you said you already tried charging your phone but it won’t respond but please do this. Once plugged in, press and hold the Volume Down and Power keys together for 10 seconds to see if the phone responds this time.

The reason why we have to do this is that there’s a possibility that the system crashed and that the battery was all drained. In this case, the phone won’t respond no matter how many times you press the Power key. It won’t also respond even if soft reset is done simply because there’s no battery left to power up all its components as well as load the firmware.

So, we give your phone a stable power source and even if it doesn’t respond to the charger, you have to do the soft reset procedure again to see if it turns on this time. If the phone still won’t respond after this, then leave it plugged in for 10 minutes but from time to time, check if it’s heating up because it does, then there’s a problem with the hardware and you need to unplug the phone from the charger and immediately bring it to the tech.

Step 3: Attempt to boot it up in Safe mode

You only have to continue troubleshooting if your phone doesn’t heat if charged. After leaving it plugged in for at least ten minutes, you have to try to bring it back to life by attempting to boot it up in a different environment.

By booting your phone up in safe mode, you’re actually disabling all third-party apps. There’s always a possibility that the problem is caused by one of the app you installed on your phone. It might have been crashing a lot and caused some conflicts in the system that also resulted to a system crash.

Here are the steps on how to start your phone up in safe mode:

  1. Press and hold the Power key past the model name screen.
  2. When “SAMSUNG” appears on the screen, release the Power key.
  3. Immediately after releasing the Power key, press and hold the Volume down key.
  4. Continue to hold the Volume down key until the device finishes restarting.
  5. Safe mode will display in the bottom left corner of the screen.
  6. Release the Volume down key when you see Safe Mode.
  7. Uninstall apps that are causing a problem.

Assuming the phone started up in safe mode, then we’re halfway to fixing the problem. We just need to find the apps that might be causing the problem and if you already have a suspect, the first thing you should do is try to update all apps in your phone. Then reset the apps you suspect one by one and if the problem still won’t boot up in normal mode, you have to uninstall them. At this point though, the problem is reduced from “won’t turn on” to “won’t boot up.”

How to update apps on your Galaxy A7

  1. From the Home screen, tap the Apps tray.
  2. Tap Play Store.
  3. Tap the Menu key and then tap My Apps. To keep your apps automatically updated, tap the Menu > Settings 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.

How to clear apps caches and data on your Galaxy A7

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

How to uninstall applications from your Galaxy A7

  1. From the Home screen, tap the Apps tray.
  2. Tap Settings > Apps.
  3. Tap the desired application in the default list or tap 3 dots icon > Show system apps to display pre-installed apps.
  4. Tap the desired application.
  5. Tap Uninstall.
  6. Tap Uninstall again to confirm.

However, if the phone doesn’t boot up in safe mode, then you have to move on to the next step.

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

Your phone has a fail-safe that if the firmware fails to load all necessary files and services and gets stuck during boot up, you will still be able to run it in Android system recovery environment wherein the usual Android interface won’t be loaded. This environment is what we often call Recovery mode. The moment your phone boots up in this mode, you can already reset assured that the hardware is fine and that the problem is actually just in the system. In this mode, you can do a couple of things: first, you have to wipe the cache partition and if that won’t work, you have to do the Master reset.

How to wipe Galaxy A7 cache partition

Wiping the cache partition actually means you’re deleting all system caches created by the firmware. Once deleted, the phone will rebuild them when it boots up. If one of those files caused the problem, then this is the only thing you need to do. Here are the steps on how to boot up in recovery mode and wipe cache partition:

  1. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  2. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds, then ‘No command’ before showing the Android system recovery menu options).
  3. Press the Volume down key several times to highlight “wipe cache partition”.
  4. Press Power button to select.
  5. Press the Volume down key to highlight “yes” and press the Power key to select.
  6. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  7. Press the Power key to restart the device.

If the phone failed to start in recovery mode or if wiping the cache partition wasn’t enough to make it work normally again, then you have to reset it.

How to Master Reset your Galaxy A7

You have to do this if your phone can successfully boot up in recovery mode but the problem wasn’t fixed by wiping the cache partition. It’s very effective in addressing almost all system related issues but there’s a catch: you will lose all your personal files and data. At this point though, you have no other choice…

  1. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  2. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds, then ‘No command’ before showing the Android system recovery menu options).
  3. Press the Volume down key several times to highlight “wipe data / factory reset.
  4. Press Power button to select.
  5. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  6. Press Power button to select and start the master reset.
  7. When the master reset is complete, “Reboot system now” is highlighted.
  8. Press the Power key to restart the device.

If the problem still persists after this, then you have no other option but to bring your phone to the shop and let the tech fix it for you.
