Samsung Galaxy S6 keeps showing “Unfortunately, Contacts has stopped” error after an update [Troubleshooting Guide]

The #Samsung Galaxy #S6  is one of the most powerful smartphones in the market today and while its maker made sure everything works inside it, it’s still not free from problems and errors. That is why you may encounter hiccups from time to time and the error message we’re tackling here is just one of those.

The error message “Unfortunately, Contacts has stopped” is basically notifying the user that the app named Contacts has crashed or stopped working for some reason. It’s the app that’s responsible in managing your contacts list and it works hand-in-hand with the phone app. Based on the reports we received from our readers before, more often, this error may pop up when a number from the contacts list is dialed, although there were also cases wherein the error shows up regardless if the call is incoming or outgoing.

Troubleshooting Galaxy S6 that shows “Unfortunately, Contacts has stopped”

The purpose of this troubleshooting guide is for us to know more about the problem, know what triggered it and lastly, learn what to do to fix it. But please note that this error message can be triggered by other factors that’s why this troubleshooting guide will walk you through in safely ruling out one possibility after another since we don’t know what happened to the phone and why it keeps showing up this error. But before we jump right into our troubleshooting, here’s one of the problems we received from our readers…

Problem: Hi guys. My device is a Galaxy S6 which has been with me for more than a year now. First off, I’m not really a techie person and I use my phone for texts, calls, facebook, instagram and twitter. No games, just music and videos. Recently, it seems like its performance suddenly dropped that it now takes a couple more seconds to open apps it used to launch in a second or two before and then an error “Unfortunately, Contacts has stopped” started appearing without obvious reason. I am not sure why my device is doing this but if you guys know how to fix it, please help me… thanks in advance.

Troubleshooting: While the error is one of the most commonly reported issues since the Galaxy S5, it’s difficult to determine what triggers it since there are a bunch of apps that use Contacts app and its services. However, the troubleshooting procedure below is tailored to rule out possibilities one after another until you can pinpoint exactly what the problem with your phone is. Now, let’s begin our troubleshooting…

Step 1: Isolate the problem to know if third-party apps have something to do with it

In dealing with this kind of problem, it is imperative that you know if one or some of your third-party applications is causing the problem. These apps can be uninstalled without adverse effects on your phone’s performance so if they’re causing trouble rather than helping you, they must be uninstalled immediately. Boot your phone up in Safe mode by following these steps:

  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.

Once you’re in this mode, try to trigger the error again by either opening the Contacts app directly or by doing the things you were doing when it popped up. If the problem is fixed, that is if the error won’t show up, then it’s confirmed that your third-party apps have something to do with the issue. Then next problem is to identify which app is causing the problem.

Step 2: Clear the cache and data of  apps triggering the error

Assuming the phone rang and when you tap the answer button the error popped up, disconnecting the call. In this case, the trigger is the Phone app and while the error specifically mentioned the Contacts app being the one that crashed, you should go after the phone app first and reset it by clearing its cache and data. You may need to reset more than one app if there are others you suspect of causing this problem.

  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 taps the suspected.
  6. Tap Clear cache.
  7. Tap Clear data button, then OK.

You may also have to reboot your phone in safe mode several times while troubleshooting to test if the apps you uninstalled are the ones causing the problem.

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

After you’ve uninstalled suspected apps and the problem still persists even in safe mode, then it’s now time to assume that the problem is with the app. I’m not sure if you can still backup your contacts list but try to sync your phone with your cloud account so your contacts may also be copied or backed up. After which, try to reset the Contacts app by following these steps:

  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.

You may lose all your contacts when you do this but that’s the reason why you have to create a backup.

Step 4: Delete the system caches so they’d be replaced

The system caches are temporary files created by the firmware so that apps and other functions may work smoothly the next time you use them. Sometimes these caches get corrupted and when the system continues to use them, your device may encounter performance-related issues such as lags, freezes, random reboots and shutdowns or even app crashes. We don’t know for sure if this is the case with your device but we need to rule out this possibility by wiping the cache partition and this is how you do it…

  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.

Once the phone has successfully rebooted, try to trigger the error to know if it still pops up. If so, then you have no other choice but to do the next step.

Step 5: Perform Master Reset to bring the device back to factory defaults

The error message “Unfortunately, Contacts has stopped” is a minor problem, really, but there are times when minor issues cannot be fixed by simple troubleshooting. A reset, however, may be able to fix it but this procedure always comes at the end because of the hassle in backing up your files and data. But since you reached this point, there’s no point in turning back so backup your files and then follow these steps:

  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.

I hope that the problem gets fixed at this stage.

Step 6: Contact technician

This is your last resort and if the error bugs you that much that you can use important functions of your phone because of it, then you need to have a technician take a look at the problem. The firmware may need to be re-installed or re-flashed so the phone may work normally again.

One Reply to “Samsung Galaxy S6 keeps showing “Unfortunately, Contacts has stopped” error after an update [Troubleshooting Guide]”

  1. Hi. I have a Samsung Galaxy S6 (dual sim) and my problem is I keep getting the error message: weather daemon has stopped or, contacts has stopped, media has stopped, and many other app. error messages. I’ve tried clearing catche, disabling the apps and at times resetting to factory settings but the problem comes back. When I finish resetting the phone and connect on wifi, my phone updates a firmware and it’s never a successful update and the data is sent for analysis. I’ve tried to stop the updates thinking maybe that’s what causing the apps to stop working but the phome when connected to wifi it updates automatically. Eventually the error messages pops up, three or four days after and continue like that until I cannot use the phone.
    Please help..
