Hi everyone! First time poster, long time reader here. Just got my lifeproof case yesterday! I was very excited when it arrived, went through all the steps and videos to test and install the new case on my iPhone 4. Worked flawlessly as far as keeping the water and dirt out! My one issue, and it is a major one, is absolutely nobody can hear me when I place calls! They say it sounds as though I am in an echoing tunnel. I am wondering if those of you who have received your cases already have had this issue? I want to be sure it isn't operator error when I installed my case. I have already emailed lifeproof support, but haven't heard anything back as of yet. Any input you may have, would be greatly appreciated!
