Cannot take recent calls after upgrading to iOS 9
I've upgraded to iOS 9 last week and I found that my call functions are not working properly.
*Call history is not displaying
* Not Displaying missed calls
*Dial Pad is not active
*Cannot access favorites.
Basically I cannot access Call function window.( I don't know the correct term for that. Sorry ) If i need to get a call, i need to search it form the phone book and find the number. If it's a number i didn't save, i cannot take it.
After restarting, i can access it once. after that, it will appear blank and inactive.
PS. i've restore the phone twice and check. but it's same.
iPhone 4S, iOS 9
