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!)

    Its all about CALENDAR STORAGE
    If u disabled that app go and enable that app
    IF it doesnt work check this solution
    ->settings -> app manager -> click on right down button of ur phone (menu) -> reset all app perference
    Send ur feed back
    Remember androi.acore.process is all about CALENDAR STORAGE

  45. Fidel says:

    I’m using a Lenovo P700i and I’m having the same problem but doing the all these solutions doesn’t work for me, I’ve had it factory wiped multiple times and it doesn’t really work. So do I have to send it to the service center?

  46. Eky says:
