J7 Does Not Turn On

Problem: My samsung J7 phone died and does not want to turn on. I charged it, took out the battery and placed it back in, still it did not want to charge. I placed in a new battery and charged it  for and hour, still nothing. Please help

Solution: What you will want to do to fix this problem is to remove the battery and microSD card ( if your phone has one installed). Press and hold the power button for at least a minute. This will discharge the phone circuit and clear out the RAM of your phone. Once this is done reinsert the battery then check if your phone turns on . If it still doesn’t then proceed with the following steps listed below.

  • Clean the charging port of your phone making sure that any dirt or debris is removed.
  • Charge your phone for at least 20 minutes.
  • If you do not see any charging indicator then try using a different charging cord and wall charger.

In case the above steps fails to work then you should bring your phone to a service center and have it checked.

Solution: It’s possible that this problem is caused by a software glitch. To check if this is the case then you should perform the following troubleshooting steps listed below. Immediately check if the problem still occurs after performing a step and if it does you should proceed to the next step.

  • Try to check if an app you installed is causing this problem by starting your phone in Safe Mode. If the issue does not occur in this mode then it could be caused by an app you downloaded. Find out what app this is and uninstall it.
  • Try wiping the cache partition of your phone from the recovery mode.
  • Backup your phone data then do a factory reset.

If the above steps fails to fix the problem then you will need to bring the phone to a service center and have it checked as this could already be caused by a faulty hardware component.

The critical part is that once the phone was off, it will not booting up unless i plugged the charger (after i plugged it show charging from its last battery level eg. 60%or else)

Solution: What you will want to do first in this case is to check if a software glitch is causing the problem by starting the phone in Safe Mode. Does the issue occur in this mode? If it doesn’t then the problem could be caused by an app you downloaded. Find out what app this is and uninstall it. In case the problem still occurs in Safe Mode you should proceed with doing a factory reset. Make sure to backup your phone data before doing the reset.

If the software troubleshooting fails then try replacing the battery of the phone as this might be faulty already.

J7 Screen Is Black After Drop

Problem: i have a j7 and it falled down on floor few days ago , and  after that its wont turn on display but it’s working i receive messages and call but still display is black.

Solution: It’s very likely that the problem is caused by a damaged display. The connection between the display and the motherboard could be loose or the display itself is already damaged. The best thing that you can do right now is to bring the phone to a service center and have it checked.

J7 Stopped Receiving Emails

Problem: We have (2) J7 phones, that have stopped receiving incoming emails, but our pcs are receiving our emails. The sync is active on both phones. We have 2 other gmail accounts that are continuing to sync correctly.

Solution:  Is your phone connected to a good Internet connection? Try connecting your phone to a different Wi-Fi network then check if the issue still occurs. If it does then I recommend that you delete the email account from your phone then set it up again.
