Keypad isn't working
Hello,
I am using iPhone 5s | iOS 9.1 and I can't write numbers in the keypad.
When I try to open Settings -> Phone it takes very long time to open it and on the end it close only.
When I want to call someone, I go to the phonebook and choose the contact person.
I powered off many times the phone, but without success.
Do you have any ideas, how I can fix the problem?
