How to troubleshoot Galaxy S8 with “Contacts has stopped error”

This error basically tells us the phone is suffering from an app-related problem. It might be limited to just a crashing problem or it could be due to a serious firmware issue since Contacts is a built-in app. Usually, errors like this are not really that serious and they can easily be fixed by doing some procedures that have great impact on the app that’s crashing or to the firmware itself. That being said, here’s what you need to do about this…

Step 1: Reset Contacts

By reset I mean clear its cache and data. This will bring the app back to its factory settings while deleting all possible corrupt cache and data files. If this error is a minor app problem, then this should be the only thing you should do. But prior to this, make sure you sync the phone with your Google account and sync your contacts so that they will be backed up as there’s a chance you may lose all your contacts when you follow the steps below:

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap Settings > Apps.
  3. Tap Contacts.
  4. Tap Storage.
  5. Tap Clear cache.
  6. Tap Clear data and then tap OK.

After this, try to open the Contacts app to trigger the error and if it doesn’t show up, try making a phone call to any number in your contacts list or compose a text message and choose a contact from your list. Depending on which app triggers the problem, clear its cache and data as well by following the steps above. If, however, the problem still occurs after this, then move on to the next step.

Step 2: Observe your phone while it’s in Safe mode

All we need to know if this error shows up when all third-party apps are temporarily disabled as there is a possibility that one of them is causing the problem. We’ve already seen cases wherein third-party applications caused built-in ones to crash. Don’t worry, booting the phone in safe mode is safe and none of your files and data will be deleted.

  1. Turn the device off.
  2. Press and hold the Power key past the model name screen.
  3. When “SAMSUNG” appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see Safe Mode.

If the error still shows up in this mode, then it’s clear that your third-party apps have nothing to do with it, otherwise, you have to find those that trigger the error and do something about it.

Assuming the error still shows up in this mode and you don’t have a clue as to which of your apps is causing it, then you should try to see if there are apps that need to be updated and then update them.

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap Play Store.
  3. Tap the Menu key and then tap My Apps. To keep your apps automatically updated, tap the Menu > Settings then tap Auto-update apps to select the check box.
  4. Choose one of the following options:
    • Tap Update [xx] to update all applications with updates available.
    • Tap an individual application and then tap Update to update a single application.

If, however,  you are already suspecting an app or two, then you must clear the caches and data of those apps or even uninstall them to see if the problem gets fixed.

How to clear app cache and data on Galaxy S8

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap Settings > Apps.
  3. Tap the desired application in the default list or tap 3 dots icon > Show system apps to display pre-installed apps.
  4. Tap Storage.
  5. Tap Clear data and then tap OK.
  6. Tap Clear cache.

How to uninstall applications from your Galaxy S8

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap Settings > Apps.
  3. Tap the desired application in the default list or tap 3 dots icon > Show system apps to display pre-installed apps.
  4. Tap the desired application.
  5. Tap Uninstall.
  6. Tap Uninstall again to confirm.

Step 3: Wipe the cache partition to delete possible corrupt caches

App crashes can also be caused by some corrupt cache files, which are created by the system to make phone’s performance smoother. When some of them get corrupted but the system continues to use them, performance issues may occur which include apps crashes. You can’t delete system caches one by one so you have to delete them all at once so that the system can create new ones. You can only do so by booting your phone up in Recovery mode and wiping the cache partition and this is how you do it:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight “wipe cache partition.”
  5. Press the Power key to select.
  6. Press the Volume down key to highlight “yes” and 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.

After this and the error continues to shows, then the next step will probably fix the problem.

Step 4: Backup your files and reset your phone

The reset will surely fix errors like this assuming you didn’t modify the firmware like root it or tried to install a custom ROM. However, when you reset your phone, all your files and data will be deleted that’s why you need to make a backup especially those that are saved in your phone’s internal storage.

Prior to the reset, however, make sure you take note of your Google ID and password so that you won’t be locked out of your device. Or better yet, disable the Factory Reset Protection in your phone by following these steps:

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap Settings > Cloud and accounts.
  3. Tap Accounts.
  4. Tap Google.
  5. Tap on your Google ID email address if multiple accounts are setup. If you have multiple accounts setup, you will need to repeat these steps for each account.
  6. Tap 3 dot icon.
  7. Tap Remove account.
  8. Tap REMOVE ACCOUNT.

After this, follow the steps below to reset your device…

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight “wipe data / factory reset.
  5. Press Power button to select.
  6. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  7. Press Power button to select and start the master reset.
  8. When the master reset is complete, “Reboot system now” is highlighted.
  9. Press the Power key to restart the device.
