How to troubleshoot your Galaxy J7 with “Phone has stopped” error

Problem: Hey droid guy. I have 2 samsung devices right now and one of them is having some kind of problem. The phone i’m having problems with is the Samsung Galaxy J7 which is about 4 months old whereas my old Galaxy S5 is still doing pretty well since I bought it more than 2 years ago. the problem is that there’s an error that keeps showing up that says “Unfortunately, Phone has stopped” and it shows up every time I try to make a call. Can you please help me with it?

Troubleshooting: As the error message implies, the problem is most likely within the Phone or Dialer app you are using on your device. Usually, it’s a software bug which can be resolve by working on the affected application that is the Phone app on your Galaxy J7. Some users who have encountered similar error message on their Samsung Galaxy J7 found out that a third-party app is the trigger. This is most likely the case if the error message started to show after installing a third-party application on your phone. If you did so, then you can try to uninstall the suspected app and then see what happens afterwards. Or you can also run your device into Safe Mode. All third-party apps will be temporarily disabled when your device is in safe mode so it will be easier for you to determine whether or not a third-party app is the culprit. If the error does not show up while in safe mode, then definitely a third-party app is causing it. Removing the faulty app will be a potential solution in that case. However, if you’re still prompted with the same error message while in safe mode, then you have to consider other options.

There are some other workarounds you can try to fix the error on your end. Feel free to refer to the following solutions.

  • Release the Volume down key.

 

Now try to observe your device for a few minutes and see if the error prompt still shows up while in safe mode. Again if the error doesn’t show, it means that a third party apps is inflicting it. Try to recall which app you have installed recently and try to disable or remove the suspected app. Otherwise, try other suggested workarounds.
