My iphone 5 is on ios 6.0 and it is muting the microphone randomly when I'm talking on speakerphone... Is this a ios 6 problem?
Thanks guys... I think it's a bug in 6.0 -- it mutes out the speakerphone function mid call.
Don't recall that happening in iOS 6 with a few different devices (like an iPhone 4 and 5).
