Troubleshooting Galaxy J7 that’s not charging

If you would consider all possibilities why your phone isn’t charging, you would have a lot of things to do before you could even determine the culprit. So, in this troubleshooting, we will be taking into consideration the most common causes.

Remember, the not charging issue can range from minor apps issues to more complex firmware and hardware problems. Let’s try to rule out possibilities that can easily and safely be ruled out, so follow the steps below:

Step 1: Verify it’s not just a system crash issue

The firmware of your phone plays a great role in the charging process as it is the one responsible in allowing electricity to flow through the circuits until the battery’s full. If the firmware crashes or frozen, there won’t be anything to aid in the charging process. Therefore, you need to make sure, first of all, that the system is working perfectly fine. That being said, you need to open the back cover and pull the battery out. While the battery isn’t inserted, press and hold the Power key for a minute to drain stored electricity in some electronic components. After that, replace the battery and secure it with the back cover and then try turn the phone on and charge or immediately plug it in. If the phone charges, then problem solved, otherwise, try the next step.

Step 2: Plug in the phone to a computer or laptop

This is one way to rule out the possibility that the problem is with the charger or power adapter. If your phone responds when connected to a computer, then you need to inspect your charger for lints or debris in the port. If you can find something that might prevent proper contacts of connectors, try to fish it out with a pair of tweezers or you may give it a blast of compressed air.

On the other hand, if your J7 won’t respond when connected to a computer, then try following the next step.

Step 3: Check the USB cable or try a different one

You need to do this step in case your phone won’t respond when connected to a computer or laptop because maybe the reason why it won’t be detected is because there’s a problem with the cable. So, first off, physically inspect the cable for any breakage or lumps. Run through your fingers from one end to another to find out if you can feel something unusual. Also check both ends for debris or lint that may have prevented proper contact with the phone’s connector.

If possible, try a different USB cable. If it can get detected using a different cable, then it’s obviously an issue with the cable. You may buy a different cable or the entire charging unit.

Step 4: Check your phone’s charging port

After you’ve checked both the charger and the cable and your device still refuses to charge, then it’s time you checked on your phone’s charging port. Look for debris, lint and bent or misaligned pins. As to the debris or lint, you can easily remove them using a brush or something with pointed end. If it’s corrosion preventing proper contacts, a blast of compressed air will do the job. However, when it comes to bend pins, try to straighten them using a pair of tweezers but just be very careful not to damage them instead.
Moreover, if you can’t find anything unusual, then the problem might be with your phone’s battery or the internal circuits or just an issue with the firmware.
If your device still has enough battery left, you may try to do the master reset:

  1. Power off your Galaxy J7. Press and hold the Power key, tap Power off and then touch POWER OFF to confirm.
  2. Press and hold the Volume Up button and then press and hold the Home key. While holding both, press and hold the Power key.
  3. When the Android logo appears on the screen, release all three keys. It may take a minute before the Android recovery screen appears.
  4. While on Android recovery screen, use the Volume Down key to highlight options, in this case, highlight the option ‘wipe data/factory reset.’
  5. Press the Power key to choose the highlighted option.
  6. Press the Volume Down key until ‘Yes — delete all user data’ option is highlighted.
  7. Press the Power key to confirm the reset.
  8. Once the reset is complete, press the Power key to choose ‘Reboot system now.’
  9. The phone will restart a little longer than usual and the reset is finished.

If the problem persists after the reset, then I suggest you do the last step.

Step 5: Send the phone in for checkup and/or repair

You’ve done what you’re supposed to do. You’ve already tried troubleshooting your device but to no avail. It’s time to seek assistance from somebody who have enough or expert know-how when it comes to smartphones. So, you may go to the store where you bought it, send it back to your provider or send it to Samsung for repair depending on what’s more convenient for you. There are just problems we can’t fix on our own and it looks like the one you have is one of them.
