Most of the time, this problem is caused by damaged or corrupted data in the Contacts Storage app, often after removing Facebook or other apps that sync your contacts. Other reasons for this error can include faulty software, permission issues, or problems with sync settings after an update or after you change your apps manually.
1. Clear the Cache and Data for all Contacts Apps
Corrupted contact data is often the main reason for the acore error. Clearing the cache and data for all apps related to Contacts removes any bad sync files or incorrect settings. This lets the system create new contact storage, which can stop the crashing issue.
2. Turn off Sync for Facebook, then Delete and Restore all Contacts
Facebook’s contact sync can sometimes mess up the Contacts Storage database on certain Android devices. Turning off sync stops this from happening again, and deleting then restoring your contacts refreshes the whole database—getting rid of the damaged entries that are causing your contacts app to crash.
3. Reset the Device to Factory Settings
Wiping everything and starting fresh can fix problems that simple solutions can’t solve. A factory reset puts all settings and apps back to how they were when you first got your device. This often gets rid of anything causing the android.process.acore service to crash.
4. Uninstall Edge Browser
