I think this might be stupid but can I suppose incoming call will stop music like iPhone? I missed several calls because of assuming it will play the ringtone when calls ring
Music stops, but if you're receiving a text message, it actually will mute the call for you and play the entire notification sound over your call. A great feature! I guess MS didn't think people were going to use their WP8 devices as phones.
I have the Lumia 920. When I have headphones in, music playback does not stop for incoming calls or text messages. It does vibrate, but no sound. This is a bummer. If I'm walking down the street or have my phone on my desk at work, it's hard to feel the vibrate. Like jaqueh said, I guess they didn't think people would want to use these things as phones!!
