I've had this on 2 Bionics now (replaced my first one with a new one), and had this issue on both. Without warning, my phone's sound (speaker and earpiece) will become severely distorted. The best way to explain it is that it sounds like Nintendo (the 8-bit console). I researched this issue, and found that other people have confirmed this issue. It doesn't happen frequently, but it does happen. This just happened to me before and during a phone call. I was dialing a phone number, and all of a sudden the number tones became heavily distorted. When the call went through, it sounded as if the lady on the line was underwater. I could hardly understand her. Other times, it happens when I'm watching a video or listening to music on the speaker. The sound just gets extremely distorted and goes away after awhile. Anyone else experience this issue?
