How to Fix android.process.acore Has Stopped Error on Android

One of the most common errors encountered on Android devices is the following " Unfortunately the process android.process.acore has stopped”. This error mostly occurs when you try to access the contacts or dialer app on your phone.

You can make this pop-up go away, but it will keep coming back. It's an annoying bug that can brick your phone. If you happen to encounter this bug, try the steps below to get rid of it.

1. Update the application

It is important to check the Play Store for any new updates, especially for Contacts, Phone , and other system apps on your device. Having the latest version of the app helps ensure that any bugs that may be present are fixed. This helps eliminate any instances of having an incompatible or glitchy version.

Once you have installed the latest versions of all the apps, restart your phone and check if the error goes away.

2. Clear cache and data on all contacts apps

Clearing the cache and storage on your contacts apps will help remove any corrupted files that may be causing the error. By clearing the data for Contacts, Contacts storage , and Google Contacts sync , the apps will be reset, eliminating any related errors or cache data issues.

The Contacts app cache contains files that help it run more efficiently. Cache files are created for ease of use and to provide a better user experience in terms of speed. Clearing the cache will not put your data at risk, but the app may run slower for a while.

On the other hand, clearing the cache will remove all the files, but re-syncing with your Google account or restoring a backup will bring them back.

Facebook is also notorious for causing this error during sync, so you should turn off contact sync on Facebook and Facebook Messenger .
