Was wondering if anyone realized that all the Folio cases are defective. When the Folio flap is flipped back during a phone call, the bottom magnet causes the microphone to become distorted. You can test this for yourself when making a video and flipping the case back and forth. Apple said their engineers are notified of this issue, but no plans have come out on a fix yet. I first realized this after about a week of numerous complaints that my phone calls sound very muffled and distorted.
