Annoying contacts FC I cope with a problem which more android users have to deal with. The well known android.process.acore fc or something similar. The constantly appearing fc notifications would be caused by your crashing contact list. However i cannot find a solution for this anywhere while many users have this problem. It is really annoying when you have to open whatsapp 3 times because the whole system freezes.. Isn't there a way to hide those notifications? I'm really getting sick of it.. Any help would be appreciated, if there's already a similar post, i would be thankful if you could refer me to it. Thans in advance!

I've installed Android 4.1.2, Galaxy S Advance

Edit: I've tried the options they give in force close wiki
but reboot and reset obviously wouldn't help, and deleting contacts isn't the solution.
When i really can't use those fc's at a moment i just temporalily freeze my contactlist but it is such a hassle to do everytime. i also tried to avoid the fc, but logcat is turned off and it doesn't help.
Do you have your contacts backed up?

Try uninstalling Facebook if that is installed. If this does not fix your problem then try the following.

Settings>Applications>System Applications>Contacts Sync Adapter and press Clear Data, this error usually goes away. If this doesn't work, try clearing the data on Settings>Applications>System Applications>Contacts or Settings>Applications>System Applications>Contacts Storage.
