FYI: the top mic is used when recording video. Z Force cases cover it

[Clocks]

Everyone knows a Z Force case used on the Z Play will cover the headphone jack. But it also covers the top mic which (along with the mic on the rear/bottom of the phone) is used for audio when recording video.

I believe it's also used for noise cancelation during phone calls but I haven't been able to confirm that.

Good info, thanks!
