I am experiencing the same problem with my new IPhone 6s 64GB. Got the latest version of IOS. Sometimes when I try to access contact, it's getting stuck. That means I simply can't acces contacts in any way. This problem is only for the options under the phone icon.(contacts, phone logs, call history, keypad to call or voice mail).
* Phone icon gets stuck , but i could get a call through 3D though shortcut menu to my favorites. when i also try to access new contacts it also getting stuck. Also when stuck, my only option to search contacts is through spotlight & get a call through their.
* Also when stuck I could not access phone option under settings.
* Sometimes calls will not receive.
I have attached some files to see how my phone option is appearing when this happened.
ONLY TEMPORARY OPTION TO SOLVE THE ISSUE IS TO RESTART. BUT SOMETIMES IT WON'T HELP. I HAVE TO RESTART TWO TIME. IT SEEMS LIKE NOT THIS IS HAPPENING REPEATEDLY NOW.
Can anyone help me with this issue. Is Apple know about this ?
