I recently switched from an HTC WP7 to a Lumia 520. I noticed that when I hold the phone away from my ear and make a call, the phone does not vibrate when the call is connected. On my old phone it used to vibrate so I can hold the phone casually until it's actually connected. What I don't remember is whether this was a WP7 feature, or whether this was an HTC addon to WP7. I haven't found anything in settings that would relate to such behaviour on the Lumia 520. Question is: is call-connected vibration expected behaviour on WP8 (i.e. is my Lumia 520 not doing something it should) or do you guys not have it either?
