Fix Samsung Galaxy S6 Edge Plus error “Unfortunately, Contacts has stopped” [Troubleshooting Guide]

The error message “Unfortunately, Contacts has stopped” on the #Samsung Galaxy S6 Edge Plus (#S6EdgePlus) is referring to the pre-installed app called Contacts, which doesn’t just handle your contact list and all their relevant information but also call logs. In other words, it works side-by-side with the Phone app or the dialer like the Gallery to the Camera app.


There are two ways you can tell an app crashes; first, when the error like the one I cited in this post shows up the moment you open the app and; second, when the app closes immediately without showing any errors. The former is what we’re dealing with here and I will walk you through in troubleshooting your phone should you encounter the same error with your phone.

Before anything else, if you have other problems with your phone, make sure you visit the troubleshooting page we carved out for the Galaxy S6 Edge+ as we’ve already solved a lot of problems with this device since its release. Simply find issues that are similar to yours and use the solutions we suggested.

Troubleshooting “Unfortunately, Contacts has stopped” error

An app crash can be just a simple app issue especially if it started to occur without apparent reason or cause. However, if significant events occurred, like firmware updates,  prior to the problem, you might be looking at a possible firmware problem. That being said, it is imperative you try to troubleshoot this problem as you might be able to fix it on your own without any help from a technician. Now, here are the things you can do to try to fix this error…

Step 1: Reboot your phone

When troubleshooting app-related issues, always begin with a reboot. Apps crash all the time especially if there are a bunch of them running in the background, sharing the same resources. There are times when some apps give in to others that use more memory or have higher permissions.

A reboot will close apps that shouldn’t be running during startup and refreshes the device’s memory. It can potentially fix the problem provided the issue is as simple as that.

Step 2: Boot your device in safe mode and see if the error still shows up

This will rule out the possibility that one or some of your downloaded apps is playing a role in causing this problem. In doing this, you’re actually putting your device in diagnostic state wherein only pre-installed apps and services are running so if the problem is caused by one of the downloaded apps, then the error shouldn’t occur.

Here’s how you start your phone up in safe mode…

  1. Press and hold the Volume Down and Power keys for 20 to 30 seconds.
  2. Once you see the Samsung logo, release the Power key immediately but continue pressing the Volume Down key.
  3. Your phone should continue booting up and you will be prompted to unlock your phone as usual.
  4. You will know if the phone successfully booted in safe mode if the text “Safe mode” is displayed at the lower-left corner of the screen.

Now that your device is in safe mode, try to do the things that may trigger the error. If it doesn’t pop up, then you need to find the app or apps that causes the problem and disable or uninstall it. Begin your search from recently installed ones. However, if the problem still occurs, then it is safe assume that the problem is with the Contacts app itself or possibly with the firmware.

Step 3: Clear the cache and data of the Contacts app

Clearing the cache and data will definitely reset the app to its factory defaults and if it’s a simple app issue, this procedure will fix it. However, before following the steps below, try to backup your contacts if you can as there is a possibility they’ll be deleted.

  1. From any Home screen, tap Apps.
  2. Tap Settings.
  3. Scroll to ‘APPLICATIONS,’ then tap Application manager.
  4. Swipe right to the ALL screen.
  5. Scroll to and tap Contacts.
  6. Tap Clear cache.
  7. Tap Clear data button, then OK.

Some users reported of the same error that popped up when they tried to make a phone calls. In this case, you need to try the procedure above and if that doesn’t work, try clearing the cache of the phone app. Simply follow the same steps but choose Dialer instead of Contacts.

Step 4: Wipe off the cache partition

This procedure should be done prior to doing a reset as it basically gets rid of system caches that are corrupt or are not compatible with the system. Thus, this procedure is effective if you recently updated your phone and are experiencing app crashes or phone freezes. Aside from its effectiveness, you can also do this without compromising the safety of your data and files. You don’t need to backup anything if you’re only planning to do this but it’s still wise to backup everything before troubleshooting.

Here’s how you delete the system cache…

  1. Turn off the device.
  2. Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power key.
  3. When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
  4. When the Android System Recovery screen appears, release the Volume Up and Home keys.
  5. Press the Volume Down key to highlight ‘wipe cache partition.’
  6. Press the Power key to select.
  7. When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
  8. Press the Power key to restart the device.

Step 5: If all else fails, reset your device

App issues like this will be fixed by a reset, however, you have to go through the hassles of backing up your data and files and depending on how much data you saved on your phone, it may take an hour to transfer them over. Aside from that, it will take the same amount of time to retrieve them back to your phone. But since you’ve reached this far, you don’t have much of a choice now.

  1. Turn off your Samsung Galaxy S6 Edge.
  2. Press and hold the Volume Up, Home and Power keys together.
  3. When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
  4. Wait until the Android Recovery Screen appears after about 30 seconds.
  5. Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
  6. Press the Vol Down button again until the option ‘Yes — delete all user data’ is highlighted and then press the Power key to select it.
  7. After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.

After the reset, don’t download anything yet but try to observe if the problem still occurs. If not, try to download apps you frequently use but continue observing your device.
