Was finally able to fine a case for my Lumia 920 last week at my local AT&T store, the Speck candy shell case. Every time I had the case on and was on a phone call, literally every single person I spoke with said they couldn't hear me. I initially thought it might be the phone itself, and was dreading taking it back. Then today when I was on a call (again with the person I'm speaking with complaining about not being able to hear me), it hit me that this problem started ever since I had the Speck case on. I told the person that I would call them right back, hung up and took off the case, called back and the now my voice was crystal clear and very audible on the other end. Anywho, just thought I would share this with the board in case anyone is in the market for a case for their 920. My Speck case will be going back to the store tomorrow.
