android.process.acore force-closing due to contacts list crashing

I've installed Android 4.1.2 on the Samsung Galaxy S Advance. I cope with a problem that more Android users have to deal with. The well-known android.process.acore force-closing (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. I've tried the options they give in [force-close tag-wiki](https://android.stackexchange.com/tags/force-close/info) , but rebooting and resetting obviously wouldn't help, and deleting contacts isn't the solution. When I really can't use those FCs at the moment, I just temporarily freeze my contact list, but it is such a hassle to do every time. I also tried to avoid the FC, but logcat is turned off and it doesn't help. Isn't there a way to hide those notifications?
