    Hi,

    I'm experiencing an annoyng problem during in calls.
    It seems that when i "move" the top receiving part of the phone and "scratch" it over my ear this activate the upper microphone and send very high noise over the called device.
    I found that It happens due to rubber phone cover that propagates the noise over the top mic. It does not happens when the cover (Spigen) is off, so the cover may be the problem, but:

    I was wondering why the upper mic "activates" (i'm not in freehand mode) and if there is a way to disable it.

    Thanks
    Maxx
