alert on call wont work

[natureloves]

I have the Samsung galaxy s4 and when I'm on the phone I don't get a vibration for my message when I received it.basically I don't get no vibration for anything when I'm on call. I check the call setting and the alert on call have a check. So why my phone doesn't vibrate?

Go into system settings > sounds. Check to make sure the "vibrate when ringing" option is enabled. Let us know if you have further questions.
