Buzzing Solution.....maybe
Ok, so I have gathered that the buzzing sound is caused by the noise cancelation with the iPhone 5. The LP case uses sound vibration towards the back of the device. Since the mic on the back of the phone, between the camera and the flash, it picks up the sound of your voice and the voice of the person you are talking to, then has to determine what to block out. People with hearing aids also experience the buzzing sound, and Apple is using a similar technology.
For people that don't use a LP, enjoy your noise cancelation. For those of us with a LP case, unfortunately I think the new technology only causes issues (the buzzing in your ear ------this is NOT a solution for any muffled sound problems.)
Scotch tape over the mic. I cut two thin strips with tiny scissors, layered them, then covered the mic. You can't see the tape once the case is on. I did this today......so maybe I shouldn't be posting about it until I can further test it, however so far so good. I made two phone calls and haven't heard a buzz yet.
Now for the newton rings (aka rainbow effect, aka oil slick, aka huge pain in LP Fré owner's butts). I have tried the compressed air trick, no luck. You'll have to excuse me if I refuse to put baby powder on my $450 phone that my $80 case is protecting. I mean, I'm already using scotch tape.
I'm thinking of using either a smudge free or anti-glare Zagg cover. I've read all the other solutions, this is the only one that I think I can get to work. Thoughts?
