Huhhh? Favourite thing about the Z2, its probabbbbllllyyy because it is dam sexy! (and of course everything else, but yea. Sexy). Dbrand is awesome, I just bought from them and there's so many options and choices...I like that.
My favourite thing is the laser forcus because I like taking quick photos and I think is pretty cool to have a laser on a phone (even though you can't really see it because it's too weak)
