Help for Android.process.acore Has Stopped Unexpectedly

Updated on January 27, 2016

The Bug Android.process.acore

The first thing you need to know is that the problem is fixable, and you probably will not have to go out and buy a new phone although it might feel like that right now.

When this happened to my phone, all I could think about was how angry I was that it was not working and how much I did not need the added expense of buying a new phone. I understand, and I speak here from experience.

The primary cause of this bug with android.process.acore is a malfunction of the contacts syncing. It is heavily linked to the Facebook app and Facebook Messenger app that continuously syncs your contacts.

First Line of Defense

The first thing to do is to uninstall Facebook, which may be an option for you if you do not use it very often. If you use Facebook often, you may need to take more drastic measures like resetting your phone completely.

Uninstall Facebook and then go into your apps, selecting all apps not just downloaded ones. Look for the following two apps:

  • Contacts
  • Contacts Storage

Once you find these, click them and select "clear data". Do both and then restart your phone.

For me, the first time I had this problem, this method worked. The second time I had the problem, I had to take more drastic action.

Caution: If you reinstall Facebook, you will likely have the same problem again. In the event that you want to risk it, make sure that continuous upload sync of contacts is disabled.

Drastic Action

I always hate to do this, but sometimes you just have to break down and reset the phone. If you are like me and have a billion apps downloaded, this can be a real chore to start from scratch again. If you only have a few downloaded apps, this is really no big deal.

The benefit of resetting your phone is that you can reinstall Facebook, making sure of course that continuous upload sync of contacts is turned off of course.

So go ahead and give it a try, reset your phone to factory defaults. Sometimes it is a little fun to get to reinvent your phone again. You will be surprised how fast and smooth your phone will run after being reset.

Clean Up Contacts

Another way to try to fix the problem from happening again in the future is to clean up your contacts from Gmail in a web interface. You can find the interface here.

Go into contacts and look for weird notation in the "notes" column. When syncing with Facebook, some contacts pick up "note" junk that can be several lines long, include web addresses, foreign characters, etc.

So try cleaning up your contacts so that when your phone syncs the new data it is free of the junk.
