iPhone 5 can't hear any sound
I Have an iPhone 5 and I just noticed that I can't hear any sound coming from it. Not when I get calls or type or swipe to open and close. I went on my sound settings and I put the volume up and I can hear the test volume and everything seems to be on , but when I type I can't hear the click sounds or hear my phone ring only vibrate. Can someone help me with this I am new to this. Thanks
iPhone 5, iOS 7.0.2
