Same problem here, occurred at about the same date early sep 2013 with the same phone.... Galaxy S4, T Mobile, Android 4.2.2. The android.process.acore goes ape**** and block all apps that use the contact list: I can no longer text, phone or email, for a couple of hours. After that, everything goes back to normal for half a day like nothing ever happened. Then all hell break lose again. I called T-Mobile, Samsung and Google.
T-Mobile has the same fix for any conceivable problem: reinstall the entire system OR change the phone. How subtle!
Samsung won't deal with any client problem whatsoever.
Google was the best - hands down. They spent time with me trying to figure the problem out. Ultimately, they recommended rooting the phone - which is not great because I use wifi calling, which requires a bit of tmobile code. Frankly, I would love to get rid of TMobile's bloatware, but they have a way to control their clients with wifi calling.
Still working on getting this pb resolved.
