I got a LifeProof case from Best Buy a few days ago. Everything seemed fine at first, but I seem to be having two issues now. I was wondering if anyone else is experiencing these issues: 1) When I am talking on the phone, I occasionally get a high-pitched noise (like microphone feedback). I never got it before, so I'm wondering if the case is causing it somehow 2) I can't get the headphone adapter to screw in all the way I will probably contact LifeProof or exchange it to Best Buy due to the headphone adapter issue anyway. But I am wondering if the feedback issue is widespread.
