Hey. I have bought the new Passport and I am very happy I did it. Though, I encounter a problem I never had with my previous Q10 and Z30: while on the call, the physical keys for volume are not functioning, even though I see on the screen volume going up or down. In reality it does nothing and the real volume is very very loud.
I must add that when I listen music or watch a video, the volme keys work perfectly.
