iPhone "Phone App" unusable after iOS update - iPhone 6
After upgrading my phone's iOS to 9.1 I am now unable to use my phone app.
I press the app to make a call, it opens, freezes, then crashes.
Things I have tried:
1. Turn On and Off - Nothing
2. Hard Reset - Nothing
What works:
1. Factory Reset - If i clean wipe my phone, then the app is usable again BUT when I sync back my data from iCloud, the same problem occurs.
Has anyone solved this problem without having to reset and not use iCloud?
iPhone 6, iOS 9.1
