How to Fix “android.process.acore has stopped” Error?

The “android.process.acore has stopped” error pops up because of a bug in the core Android process. This bug is usually linked to contacts, call logs, dialers, or any other messaging application. The good news is it is not a hardware issue, and some software issues can be fixed with DIY methods. 

In this blog, I will discuss why the “android.process.acore has stopped” error appears on your device and what fixes you must implement to resolve the core android process error. Let’s learn about this issue in detail. 

Why is my device displaying the “android.process.acore has stopped” error?

The android.process.acore error is a common error faced by many Android users. Initial research suggests that devices that come without stock Android are more prone to such errors. 

Indeed, the issue has been mostly reported on Xiaomi, Oppo, ZTE, and other budget smartphones that run on modified or custom ROMs with inconsistent updates. Android devices with custom skins may have bugs due to pre-installed bloatware and apps.

So, the error is more likely to appear on non-stock Android. Let’s first understand the common cause behind this issue: 

1. App compatibility issues – The error may occur due to an incompatibility problem while sharing or syncing data between the contacts app and any other application needing contacts permissions or trying to Sync contacts.
2. Corrupt data – The most common cause of this error is corrupted cache data in your contacts app. Android OS uses cache files to store temporary data, and if any of these cache files become outdated, it can lead to data corruption and issues with core Android processes. 
3. System updates – Incomplete updates or pending app and operating system updates can also cause this error. If you have a custom Android, you can face this glitch after updating to a new version, which can introduce bugs. 
4. Storage Issues – Your Android device can also face this glitch due to low storage space.
5. App-related issues – Sometimes, even apps installed on your device can crash the Android acore process. This could be related to outdated app data, problems with OS version compatibility, or data synchronization issues between the OS and the application.
6. Malware or virus – Yes, malware or virus can also be a potential cause for this error. Try running an antivirus scan on your Android device to prevent malware infection. 

Methods to Fix the “android.process.acore has stopped” error?

There is more than one method to fix this error. You may resolve this issue even with the most basic troubleshooting, such as restarting your device or clearing the app cache. But if not, the last and final fix would be to try a factory reset. This has its complications, but don’t worry—I will answer all the questions you have.

Method 1: Restart device to fix android process acore error

Restarting your Android device is one of the most basic troubleshooting methods you can apply to fix it. It helps clear any temporary glitches that may be causing this error. Restart your device, wait for some time, and see if the problem is resolved or still popping up. As said earlier, if you are lucky, you may be able to fix it with the help of an easy and quick restart, but if not, you may need to switch to other solutions.

Method 2: Remove and re-add Google accounts to fix android process acore error

I am a bit skeptical about this particular solution, but giving it a try will not do any harm. Data synchronization trouble, one of the main causes of this error, can also pop up due to problems with your Google accounts. You can refresh your account’s login information by removing and re-adding your account. 

Note: The methods may vary depending on the device manufacturer. 

• Head to your device’s settings and look for the Accounts section.
• Now go to Manage Accounts, and you will find your Google Account login details.
• All your account details will be listed here. 
• Click on the Google accounts that are logged in your device and then hit Remove Account. 
• Your selected account will be removed from the device. 
• Do this for all the Google accounts you want to remove. 

Once you remove your Google account, restart your device and clear the junk files. This will ensure your account is correctly removed from the device. 

• Now, to Add an account, scroll down, and click on the Add Account option. 
• Click on the Google logo from the list showing all types of accounts. 
• Now add your Google account login details, and you are done. 

Method 3: Update apps to fix android process acore error

Outdated software or pending app updates can be a potential cause of this issue. Hence, try to update your device apps, especially those more likely to be associated with this error. First, try updating all your social media messaging apps such as WhatsApp, call monitoring, spam blockers, and contacts apps. See if the problem is resolved or if you need to try any other method. 

Also, check for OS updates and if required, update your device to the latest Android security patch and version.

Method 4: Reset app preferences to fix android process acore error

When you see the message “android.process.acore has stopped” on your Android device, it indicates an issue in any app that helps manage contacts on Android device.

• Look for “Apps” or “Applications” from the menu.
• Now click on the three dots in the top-right corner to open the menu.

The above steps may vary depending on your Android device.

Method 5: Clear contacts app cache data to fix android process acore error

• Go to Settings > Apps > Contacts.
• Now tap on Contacts and look for the Clear Cache option. 
• Select Clear Cache to delete the temporary files.
• Once you clear the cache, restart your device. 

Once your device is on, check for the issue. If the android.process.acore has stopped, the error still appears, and you can try the next method.

Method 6: Clear system cache partition to fix android process acore error

If removing the contacts app cache data was of no help to you, you can try removing the system cache partition on your Android device. This can help fix the “android.process.acore has stopped” error because it will remove all the temporary system files which may be causing issues. Clearing the system app cache will not delete your important data or personal files. This can also help you optimize your device performance with faster app load time. 

• Boot your device in recovery mode by simultaneously pressing the volume up and power button until you see the recovery menu. 
• Use the volume up and down buttons to navigate to Wipe Cache Partition.
• Now press the power button to select this option.
• Once this is complete, restart your device by pressing the power button. 

Now check for the issue. If your Android device is displaying the “android.process.acore has stopped” error, you can try this last method which will fix this error.
