When I call someone they can barely hear me?

I have an iPhone 3S and when I call someone or they call me, it sounds like I'm whispering to them and they can BARELY hear i have to yell into my phone so they can tell what I'm saying. I didn't drop my phone or anything it just happened, can anyone help?

I recommend you contact apple, it sounds like your internal mic is damaged
do this by going to apple.com and click some sort of contact tab, find a
phone number and enquire

  • Will it show up as a missed call if i call someone by accident for half a ring? So I accidentally called my ex on his iphone, but I quickly realized my mistake and hung up after a half ring. Like you know how when you're calling someone it rings, I hung up after the first riiiing. My question is, will it show up on his phone as a missed call? I tested it out on 2 friends. One iphone 5 and iphone 4. They both told me they didn't get a call. Am I in the clear?

  • Why can't I hear anything when I call someone? (iPhone 3GS)? I still have an iPhone 3GS and recently I have found that whenever I make a call or receive a call, I can't hear the person on the other end, but they can hear me. It doesn't work when it's on speaker or headphones either. But whenever I listen to music or sound from an app I'm hear it fine. I have tried a hard resets and I don't know what to do. How can I fix this?
