And chances are that you will be able to fix it without seeking anyone’s assistance. Let’s take a look at the reasons why the Android Process Acore Has Stopped error occurs and how you can fix it.

All versions of the Android OS have a built-in Contacts app that enables you to store and manage your contacts. The Android Process Acore Has Stopped message usually appears when you try to launch the Contacts app and it denies you access to your contact list.

App compatibility issues are the most common reason why this error occurs, and it is usually associated with Facebook and Contacts apps. However, besides the apps that are running in the background, this problem can also be caused by an unsuccessful installation of a custom ROM, an incomplete system update, or a virus.

How to fix the Android Process Acore Has Stopped Error?

The solution to this problem depends on the Android phone model and the underlying issue that prompted the OS to display the message. So, you should try different methods until you find the one that does the trick for you.

Here are some of the most common fixes of the Android.Process.Acore Has Stopped error.

Restart Your Phone

Although it may seem unlikely that a simple restart will resolve an error that seems so serious, in most cases, performing a reboot is all it takes to make this problem go away. Press and hold the Power button on your phone until you see the Shutdown and Restart options, then tap on the Restart icon and wait for the OS to load.

Try to launch the Contacts app to see if the issue is resolved, and proceed to the next step if restarting the device didn’t have the desired effect.

Clear the Contact’s App Cache

Emptying the app’s cache will usually resolve problems it encounters, and for that reason, it is worth checking if the cache of the Contacts app is overloaded. To do this you have to open the device’s Settings app, locate the Apps menu, and then navigate to the Contacts app.

Find the Storage option within the Contacts app, and then tap on the Clear Cache button. You should keep in mind that the Contacts app is a system app and you cannot uninstall it so clearing its cache is the next best thing you can do in an effort to get rid of the Android.Process.Acore Has Stopped error.

Check if the Facebook App Is Disabled

The Facebook contacts syncing API can create a conflict with the system Contacts app if the Facebook app is disabled on your phone for whatever reason. If in fact, Facebook is the reason why you’re seeing the Android.Process.Acore Has Stopped message, you just have to make sure that the app is enabled.

Head over to the phone’s Settings, then open the Apps menu and check if Facebook is disabled. After enabling the app you should try accessing your contacts list to see if the problem was fixed.

Wipe Your Phone’s Cache

Wiping a device’s cache will delete all temporary files which can help you get rid of a virus you accidentally picked up while browsing the Internet. Although, this process isn’t difficult it can get a bit technical.

Step 1 – Use the Power button to switch off your phone, and then hold the Power and Volume Up buttons in order to gain access to the device’s Recovery Mode.

Step 2 – Navigate through the Recovery Mode menu using the Volume Up and Volume Down buttons and select the Wipe Cache Partition option. Your phone will start deleting all temporary files, and you should restart it once this process is completed.

Reset the Phone to Factory Settings

If the Android.Process.Acore Has Stopped message keeps showing up after you tried all of the above methods, then you should reset the device to factory settings. Before doing so you should backup all the data stored on your phone to avoid losing it.

When ready, go to the Settings app and open the System menu. Tap on the Advanced option, access the Reset features and choose the Erase All Data (Factory Settings) from the menu. You will be asked to insert the PIN code before the process begins, and the device will delete all data afterward.
