IPhone 4 and the stupid mute button

I have a iPhone 4 and I've had it for a while and I love it. I just have 1 issue - I have a boyfriend and I have a mute button.,. We talk on the phone constantly and I think it irritates him and me at that! Is there something I can do to prevent my face from hitting it or something dang… One thing I do refuse to do though is restore my phone AIN'T NOBODY GOT TIME FOR THAT!

When you get the call put the iPhone in standby and there's no way you'll hit that mute button.

It shouldnt do that.once your face cover you phone when youre talking on the phone, it's a black screen. Just don't put your whole face on the phone…
