I started getting that error that android.process.acore stopped and it keeps popping up. Now any app that hooks into my contacts is unusable such as the dialer and hangouts. So I can't make calls or text. I tried emptying out the contacts and contacts storage but this didn't do anything, so I'm thinking it has to do with another app that is using my contacts but I can't tell which one. The only changes I made to my apps was updating my apps which is done automatically in the background. The ones that were recently updated were Airbnb, Android System WebView, Expedia, Google Play Movies, IMDb, Kitty in the Box, LinkedIn Job Search, Mint, MyTSA, ooVoo, Pandora, Pinterest, Pizza Hut, Snapchat, Swarm, Tapatalk, Target, Tumblr, Twitter, UPS Mobile, Venmo, and Yahoo Weather. I could really use some help with this. I'm running out of ideas and this is really worrying me.
