Android OS since the very beginning has been about branching and spreading out to as many users as possible. Unlike the closed-circuit iOS, the extended number of Android OEM manufacturers such as Samsung, Huawei, Sony, and many others have helped the mobile operating system spread out to billions of users across the world. However, the very nature of Android OS that makes it so accessible also creates a bunch of errors too.

How to Fix the android.process.acore has stopped Error

For instance, the android.process.acore has stopped error keeps popping up on certain devices, bugging users when accessing the People app. The People app or Contacts app is built into the system, which makes it impossible to ignore or avoid using. The good news is that there is not just one, but multiple ways that can be used to counter this.


Since not every Android device from different OEM brand is designed the same way, one solution that works on one device might not work on the other. This is why we’ve sieved through the support forums to understand the issue behind the android.process.acore has stopped error. So here are the best ways to fix it for good.

Solution No. 1: Reboot your Android

The most basic solution when it comes to fixing any issue pestering a tech device is a simple reboot. While this may seem too easy of a fix for an error that just won’t go away, you’d be surprised by how often turning a device off and then on again is the only fix you need. Whether it is a broken service or just a background app that is conflicting with the system, a simple reboot can fix it all.

auto restart on Samsung Galaxy

  1. Press and hold down the Power button on your Android until the boot pop-up window is displayed on the screen.
  2. Depending on your device, select the Restart or Reboot button and wait while the process completes.
  3. Once your device reboots, check to see if the Google app that was giving back the error has been resolved.

Solution No. 2: Clear the Cache of the Contacts app

Based on the experience of users who have been trying to look to fix the android.process.acore has stopped error, the issue is tied to the Contacts app. Since the Contacts app is a system app, you can’t uninstall and reinstall as you would a third-party app. The easiest solution here is to clear the cache of the Contacts or People app on the device.

  1. Head over to the Settings app on your Android using the app-drawer or the gear icon in the notification window.
  2. Scroll down to find the Apps menu in the Settings. The menu may be named Application Manager on certain devices.
  3. With the entire list of apps on your phone in front of you, scroll down to find Contacts or People app.
  4. Press the Clear Cache button and confirm your action.
  5. Head back to the home screen and reboot your device to make the changes you’ve just made set in.

Clearing the cache of the Contacts app will not affect the contacts saved on your device. It will remove temporary files and any other broken elements that may be related to the android.process.acore has stopped error.

Solution No. 3: Facebook could be the culprit

The largest social media network has been accused of a lot of things lately and rightfully so. It seems that causing the “android.process.acore has stopped” error is included among Facebook’s mischiefs too. Based on the reports from users, it seems that the error is far more frequent when the Facebook app is disabled.


In case you have the Facebook social media app disabled on your Android device, you need to enable it:

  1. Head over to the Settings app on your Android using the app-drawer or the gear icon in the notification window.
  2. Scroll down to find the Apps menu in the Settings. The menu may be named Application Manager on certain devices.
  3. With the entire list of apps on your phone in front of you, scroll down to find the Facebook app.
  4. Make sure that the Facebook app is enabled.

The issue is allegedly linked to the Facebook contacts syncing API which creates a conflict with the system Contacts app. Once you have the Facebook app enabled again, the issue should no longer bother you.

Solution No. 4: Clear the Cache of the Contacts Storage app

Simply clearing the cache of the Contacts or the People app does not do the trick for some users. However, the issue has also been encountered by Android TV users who have no contacts stored on the system. In such cases, the Contacts Storage API of the Contacts app could be the problem.

While you can clear the cache of the Contacts Storage app as well, this could delete your contacts. This is the reason we highly recommend


  1. Head over to the Settings app on your Android using the app-drawer or the gear icon in the notification window.
  2. Scroll down to find the Apps menu in the Settings. The menu may be named Application Manager on certain devices.
  3. Tap on the three-dot menu in the top-right corner and select Show system apps.
  4. With the entire list of apps on your phone in front of you, scroll down to find Contacts Storage app.
  5. Press the Clear Cache button and confirm your action.
  6. Head back to the home screen and reboot your device to make the changes you’ve just made set in.

Solution No. 5: Wipe the Device Cache

This specific error has been linked to contacts and the Facebook app in general. However, there might be other players in the mix behind the android.process.acore has stopped error. If clearing the cache of these specific apps does not fix the issue, you can try clearing the device cache. The next step of action is accessing the Recovery menu and using the “Wipe Device Cache” function.

  1. Press and hold the Power button to turn off your Android device.
  2. Once the device is turned off, simultaneously hold the Power button and Volume Up button until the screen boots up.
  3. This will launch the stock recovery mode on Android give you the ability to wipe device cache.
  4. Using the Volume buttons for navigation, move down to select Wipe device cache and wait for the device to reset.
  5. Once the device cache has been wiped clean, restart your Android device.

This option will not delete the apps on your device, but it will clean the temporary files and stored settings. With any broken or corrupt files out with the device cache cleaned, the android.process.acore has stopped error should be fixed.


Solution No. 6: Replace the Contacts app

If all other solutions fail to help you get rid of this annoying error, it’s time for the nuclear option. Thanks to the Google Play Store and the millions of apps it offers, you can even replace the system Contacts app and grab a worthy alternative that gets the job done. For this specific guide, we tested Drupe Contacts & Caller ID app, but you can grab any preferred third-party app.

Note: Before you proceed to disable the system Contacts app, make sure that you export your contacts and create a backup.

  1. Head over to the Settings app on your Android using the app-drawer or the gear icon in the notification window.
  2. Scroll down to find the Apps menu in the Settings. The menu may be named Application Manager on certain devices.
  3. With the entire list of apps on your phone in front of you, scroll down to find Contacts or People app.
  1. Press the Disable button and confirm your action to disable the system Contacts app.
  2. Now go ahead and install your preferred third-party contacts app and import the contacts you had previously backed up.

Solution No. 7: Factory Reset

In rare circumstances where you still can’t get rid of the annoying error that pops up, there’s only one solution. You will need to factory reset your Android entirely in the hopes that the issues will be fixed. A clean slate should get rid of whatever issue is plaguing your Android device and causing the error message.

  1. Turn off the device, and then press and hold the Volume Up and Power button simultaneously.
  2. Release the Power button when the device logo appears, but continue to hold the Volume Up button.
  3. On the Android recovery screen, use the Volume Down button to navigate down to wipe cache partition and press the Power button to select it.
  4. Use the Volume Down button to select Yes — delete all user data, and then press the Power button to confirm.
  5. Wait for the reset to finish and press the Power button when prompted with the message to Reboot system now.
