Vibrate not working at all with iOS7

I updated to iOS7 the day it came out and thought all was going fine but only now, I'm realizing that the vibrate feature hasn't worked once since.

 

Prevoiusly, I just thought that it doesn't vibrate when my phone is plugged in (when I'd receive text messages) but it just dawned on me that it hasn't vibrated at all since. When I switch from Normal mode to Silent mode, no vibration. When I go to settings and try out the different Vibrate modes, I feel nothing. My phone doesn't vibrate when I plug it into my laptop as well. I'm wondering something happened between when I upgraded to iOS7?

 

Is there any way to troubleshoot this problem?

 

I just reset my iPhone today (all content and settings) and restored it to a recent backup but still the same issue.

 

Do you think I should just take it to an Apple Specialist at the Apple Store?

p.s. the iPhone is less than a year old
