Does anyone have a echo or hollow sound when talking on their iphone 5

I do. Any fix?

me too, I thought it was my case but it doesnt seem like it now. Any fix?

This happened to me also it happened when my gf called me and had me on speaker phone.. She has an iPhone 4 and it was like a hollow tone and could barely hear her also made my head feel hollow and felt light headed and got a headache right after!!! Every time I get a phone call I'm tripping that it will happen again... Lol

I brought a new iphone a few days ago and have the same problem,

Is there any way to fix the problem?

your phone is haunted 0.0

I heard it again and figured it out.. Its the mic on the back by the camera lens! If u start to hear that hollow noise just put ur finger on the mic and that hollow noise goes away.. Its annoying but it helps stop the hollow tone thing or what ever you want to call it
