No, well Its weird. The volume control (in the left side of the Iphone) has to buttons, one to turn volume up, and one to turn it down. I cant turn volume up. And even dough the volume in the settings is turned up 100 percent, when (during a call) I can press the turn down. When I do that, I am able to see that the volume is 40% down, and I can decrease it. But not increase it.
