My new iPhone 5 (IOS 7) has a weird problem where it doesn't play any vibration patterns that I set or choose from the list. The only thing it does when I get a call is vibrate constantly with no breaks. Even if I set a pattern, it just plays back a long vibration. The vibration is also a little louder than on other phones. Is there an issue with the vibration motor, or could it be the software (highly unlikely, in my opinion). I've restored, restarted even updated the software and did everything that I possibly can without jailbreaking and it hasn't fixed it. What can I do about this? Get the vibrator replaced?
