How to Fix the “android.process.acore” Problem on an Android Device

Edit: Some people have reported in the comments that this solution DOES DELETE YOUR CONTACTS. Use at your own risk!

The problem:
Your Android device (tablet, phone, Android TV) gives you the following message.

“The process android.process.acore has stopped working.”

The solution:
Settings –> Applications –> Manage Applications –> All (button on the top that lets you see all applications) –> scroll down to “Contacts Storage” –> Click on “Clear Data”.

This worked on my Android TV and I have seen reports of it working on other Android devices.

I do not have any contacts stored on my Android TV, so this solution did not cause any problems with my device. If you are using a contacts list on your device, I cannot say whether this will cause problems with your list of contacts. If you think it might, please look for another solution. (If anyone is brave enough to try it anyway, please let me know!)

    Brilliant. I had just installed the CM ROM as well as the google apps, when this error message came up. I looked at and read a whole bunch of sites, but you were the only one to explain how to solve the problem on my Nexus 7.

    Thank you very much.

  16. don

    The screen has the message in a window that is on top of the main screen with a “force close” button. Can’t get to anything because of this. I have tried reset; unplug battery; remove microsd. What now?

    The solution is simple…uninstall Hotmail and any other app from Microsoft.

  18. kashif Saeed

    Only Deleting the data of Contact/-Storage Service and so on .. didnt fix the problem for me. (Android 2.3.7)

    But Uninstalling all Microsoft apps (including Skype) worked for me.

    I guess if that doesnt help its worth a try to uninstall all applications that use your Contacts or sync with them.
