Bad sound quality

Mar 25, 2013
Since some time now I have a very annoying whine in my video's that I caputure with the M2. Didn't had that in the beginning, but now in every video I take with the phone.

I made a testvid:
you can hear it the first 5 seconds, but most in most footage its there the whole time.

Also, when I call someone, there is a fair amount of static noise. The other person hears me fine.

holy sh**, this is the same as what happens in my phone, ever since QS99 stock ROM -> 3.2.xx

Note sure about after I went to V5 due to never testing any mp3.

Maybe a batch of lousy MI-2 hardwares.
