Troubleshooting Galaxy J7 that won’t charge

We have to troubleshoot your device to know what the problem why it’s not charging anymore. The course of our troubleshooting would be to rule out one possibility after another until we can arrive at a conclusion and pinpoint what the cause is. By that time, we would already know what to do to fix the problem. Here’s what you need to do…

Step 1: Perform the battery pull procedure to rule out the possibility of a glitch

Glitches happen all the time and when they do, various things could happen. We’ve seen not charging issues before caused by a glitch and while it can easily be fixed by a reboot, there’s one thing I want you to try that’s more effective than the normal restart. It’s often called the “battery pull” procedure and here’s how you do it:

  1. While the phone is powered on, remove the back cover.
  2. Pull the battery out of the phone to ‘power shock’ it.
  3. Now press and hold the Power key for a minute while the battery is out.
  4. Replace the battery and secure it with the back cover.
  5. Turn the phone back on and attempt to charge the phone.

If the problem still happens after this, then move on to the next step.

Step 2: Attempt to charge the phone while in safe mode

It’s possible that one or some of the apps in your device is causing the problem, although we don’t know for sure which one it is. We have to isolate the problem by booting it up in safe mode so that, at least, we would know if the cause is a third-party app or pre-installed one. Here’s how you boot your phone 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’.

Once the phone has booted successfully in safe mode, attempt to charge it up if it responds. If it does not, then try the next step.

Step 3: Attempt to charge the phone while turned off

Now, let’s try to see if the phone would charge if nothing is running in the background. So, turn your phone off and connect the charger. It should still display the charging symbol on the screen as well as light up the LED indicator at the top of the display. These signs are would tell you if there’s something wrong with the hardware or not. So, if the phone doesn’t charge even if it’s powered off, we need to look at the possibility that the charger or the cable is damaged.

Step 4: Physically check the charger and the USB cable

Just by looking at the charger and into its USB port, you can tell right away if there’s a problem or not. If the port is corroded by anything, then that might be the reason why the phone cannot charge because the cable couldn’t make proper contact with the receptors. You may try cleaning it out or blasting compressed air into it to get rid of lint or debris. If everything looks normal, then proceed with the checking of the cable.

Just look at both ends to spot something that’s not normal like bent pins, rust, corrosion or anything that also hinders it from conducting electricity. If both ends look normal, then run your fingers from one end of the cable to the other to feel some lumps, which could be a sign of breakage inside the insulation.

Another way to check if the cable is good is by connecting the phone to a computer. If it gets detected, then the cable is just fine. Try to see if the device charges when connected to a computer. The machine may not give out the amperage to charge the battery at the same pace as when it’s charging using its original charger but, at least, it will give you an idea if the phone charges or not.

Step 5: Check the charging port on your Galaxy J7

Assuming nothing is wrong with the charger and cable, at least, physically, then it’s time you checked the phone’s charging port for lint, debris, corrosion and bent pins. For lint and debris, you can try fishing them out or you may also try blasting compressed air to get rid of them. As to the corrosion, you need to clean it out with an alcohol or anything that dries out after a few seconds. If it happens a pin or two is bent, try to straighten it out using a pair of tweezers but be very careful not to damage them.

On the other hand, if the charging port doesn’t show any signs of abnormality, then move on to the next step.

Step 6: Try to delete the system cache as some of them may have been corrupted

This is a long shot but I personally know cases wherein the phone doesn’t charge after an update. It’s a sign that some of the system caches may have been corrupted including the cache for the service that handles charging. While we don’t have access to such caches, we can actually delete them to force the phone to create new ones that are completely compatible with the new system. Don’t worry, none of your files and data will be lost and here’s how you delete those caches:

  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.

If the phone still won’t charge after wiping the cache partition, then you have no other choice but to reset your phone.

Step 7: Prior to sending the phone in for repair, do the reset and see if that makes a difference

It appears as though the problem is due to a hardware issue, although we can’t pinpoint which is which. So, you need help from a technician who can do further tests to know what the problem is all about. However, before you send the phone in for repair, I advise you to do the reset to rule out the possibility that the problem has something to do with some system files or data and at the same time you can clear off all your personal information. Also, make sure you backup your files and data as they will be deleted. But before the reset, make sure you disable anti-theft so you can avoid being locked out, here’s how…

  1. From the Home screen, tap the Apps icon.
  2. Tap Settings.
  3. Tap Accounts.
  4. Tap Google.
  5. Tap your Google ID email address. If you have multiple accounts setup, you will need to repeat these steps for each account.
  6. Tap More.
  7. Tap Remove account.

And this is how you reset your Galaxy J7…

  1. Back up data on the internal memory. If you have signed into a Google account on the device, you have activated Anti-theft and will need your Google credentials to finish the Master reset.
  2. Turn off the device.
  3. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  4. When the device logo screen displays, release only the Power key
  5. 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).
  6. Press the Volume down key several times key to highlight ‘wipe data / factory reset.’
  7. Press Power button to select.
  8. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  9. Press Power button to select and start the master reset.
  10. When the master reset is complete, ‘Reboot system now’ is highlighted.
  11. Press the Power key to restart the device.

Alternatively, you can also do the reset via settings menu…

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